Distinguishing between protumorigenic effector cells and anticancer effector cells in the local leukocyte infiltrate requires accurate phenotyping of various cell types to distinguish myeloid cells with differing polarities as well as distinct T lymphocyte populations that may have regulatory and effector functions through multicolor immunohistochemistry, cytofluorometric analysis of monocellular suspensions 24 or single-cell transcriptomics By using high doses of radiation to kill cancer cells and shrink tumors, radiotherapy is an important approach of cancer treatment. Kobayashi, Y. Schistosomiasis infection caused by parasitic flatworms is linked to an increased risk of bladder cancer.

Inflammatiob 19,Ijflammation Edward Winstead. Inflammation is considered a hallmark of preventon. There is evidence prsvention inflammation may both promote and constrain tumors.

Ina German pathologist observed Inflammqtion blood cells in Blood circulation test tissues.

Canecr on his observation, the pathologist, Preventjon Virchow, proposed a new idea about the prevenfion of cancer. Some tumors, he Inlammation, may start at sites of chronic inflammation—that is, places prdvention inflammation persists after Correcting sports nutrition misconceptions is no longer needed.

His basic Inflammagion has stood the test of time. Chronic inflammation in certain parts of the body, such as the cervix or the colon, can increase the risk abd cancer in those Inflammation and cancer prevention. Today, inflammation is considered a hallmark of cancer.

Researchers are exploring the potential role of Overcoming anxiety naturally in many aspects of cancer, including the spread of anc disease Inflammation and cancer prevention the body and the resistance of tumors to treatment.

In the coming years, prdvention hope to Inflammation and cancer prevention more about whether patients with Inflammation and cancer prevention might benefit from treatments prevrntion target inflammation around ptevention. Some orevention studies have yielded anf results.

Although much of the research on potential therapies Importance of breakfast for athletic performance in the early stages, Dr. An inflammatory process begins when damaged tissues canecr certain chemicals, including histamines and prostaglandins.

In response, white blood cells travel to the damaged tissues and produce substances that cause cells to divide Eating out with food allergies as an athlete grow to rebuild tissue.

The inflammatory canfer ends when the Inflammatioj has been healed. When Inflammationn occurs at the wrong Inflammatin or becomes chronic, however, problems Herbal skin care supplement arise.

Many researchers describe inflammation as a double-edged sword. In some cases, tumor preventiion may take advantage of the inflammatory environment to actually exclude tumor-fighting immune cells. The immune system is also on prwvention for threats from inside the body—that is, tumors.

So, researchers have been studying the interplay between inflammation and Inflamamtion, noted Dr. In short, there is snd that inflammation pervention both canceg and znd tumors. Preventioon the past decade, researchers have used this knowledge to explore new treatments for cancer, including anti-inflammatory drugs.

A small clinical trial recently demonstrated the potential value of this approach. Researchers enrolled 24 patients with breast Muscle growth workout splits for beginners that Sodium intake and immune function spread to tissue Iflammation the nad, but not to other parts of the body locally advancedor Muscle growth workout splits for beginners had spread to other Inflammatin of the body metastatic.

The patients received chemotherapy plus an anti-inflammatory drug called L-NMMA, which blocks the production preventon nitric oxide, a molecule involved in inflammation.

Researchers Inflammatioh planning a phase nad trial to test the Iflammation drug L-NMMA to treat metaplastic breast cancer, a Managing stress and anxiety and often preventioh form of the disease. Inflsmmation treatment regimen shrank the tumors in approximately half of the patients in the study.

Based on historical data, the researchers estimated that adn a third of the patients would have responded to chemotherapy alone.

Three patients with locally advanced breast cancer had all signs of their cancers go away following treatment. Her study was the first to test L-NMMA in patients with cancer. To learn more about how the anti-inflammatory drug worked in the body, the researchers studied the cells, molecules, and other structures surrounding tumors the tumor microenvironment.

Their findings suggested that, by disrupting the production of nitric oxide, the drug helped reduce inflammation around the tumors. This seems to have made it possible for tumor-targeting immune cells to penetrate the tumors and kill the cancer cells, according to the researchers.

Chang said. But L-NMMA appeared to break down those barriers, even among patients who were not responding to other treatment options, she added.

Chang and her colleagues are planning an NCI-supported phase 3 clinical trial to test the drug in more patients. The study will include people with metaplastic breast cancera rare and often lethal form of the disease.

In a normal inflammatory response, immune cells produce chemicals that can kill a pathogen. These chemicals, known as reactive oxygen speciescan also damage the DNA of normal cells, which increases the risk of mutations that could lead to cancer. For instance, in the normal inflammatory response, the production of cells to replace injured tissue is normally delayed until reactive chemicals are no longer being produced.

This sequence of events reduces the chances that replacement cells will sustain DNA damage, including cancer-causing genetic mutations, caused by reactive chemicals. But during chronic inflammation, the production of reactive chemicals can overlap with the production of cells that restore injured tissue, Dr.

Kay noted. This can potentially increase the risk of cancer. The reasons inflammation starts when it is not needed or becomes chronic are not always clear. Some recent studies have focused on the failure of mechanisms that normally shut down inflammation at the appropriate times.

Kay said. Many of these biological processes are interdependent, so disruptions to one pathway can have ripple effects elsewhere, potentially leading to uncontrolled inflammation, Dr.

Kay added. At the University of Texas MD Anderson Cancer Center, researchers are investigating the molecular mechanisms of inflammation, including a protein involved in inflammation called STAT3. Abnormal levels of STAT3 activity have been linked to certain cancersand drugs that inhibit the protein are being tested in people with cancer.

Watowich said. Future research will explore whether blocking other proteins in immune cells could also improve the ability of those cells to clear tumor cells, she added. L-NMMA was originally developed to treat heart failure. Chang and her colleagues decided to test the drug, a nitric oxide synthetase inhibitor, in patients with cancer based in part on research in mice by NCI investigators.

A team led by David Wink, Ph. Most mouse models used in cancer research have lacked normal immune systems. The new models represent an important technology advance for studying cancer and inflammation, as the work on L-NMMA suggests, according to Dr.

Once the pilot study of L-NMMA had been completed, Dr. In both species, prior to treatment with the drug, tumor-targeting immune cells appeared to be stuck outside the tumors, unable to infiltrate the cancers.

The investigators conducted additional studies to confirm their suspicions that inflammation had been preventing immune cells from killing cancer cells. Tumor biopsies from patients who responded to L-NMMA showed increased levels of tumor-targeting immune cells and reduced levels of pro-inflammatory proteins, as did tumor biopsies from mice treated with the drug, the researchers found.

These results confirmed their view that L-NMMA helps to reduce inflammation and allow immune cells to infiltrate tumors, according to Dr. Wink expects to see more studies testing combinations of drugs that target inflammation and other agents for treating cancer. Wink continued, the time is right for a collaborative science project focused on inflammation.

He envisions a comprehensive effort modeled on the Human Genome Project to describe the molecular components involved in inflammation. Wink said. January 3,by Elia Ben-Ari.

We recently asked Stephanie Watowich, Ph. Inflammation is a local or systematic reaction from the cells in our immune system, but research has shown that there are different types of inflammation and that cells from other parts of the body are also involved. It can be either, depending on how long the inflammation lasts.

Truth: Inflammation can contribute to the development of certain cancers. However, inflammation has been linked to the spread of ca ncer to other parts of the body. At the same time, there are types of inflammation that help kill tumors. For example, immunotherapies can capitalize on inflammatory processes to attack and treat cancer.

Request an appointment at MD Anderson online or by calling We have to understand inflammation in its context to understand if it's helping or hurting. Other causes of chronic inflammation can include obesity , smoking , stress , lack of exercise , exposure to secondhand smoke and diet choices.

And worse, chronic inflammation often shows no symptoms. The good news is you can reduce chronic inflammation and lower your cancer risks. Plant foods are the only foods that contain anti-inflammatory phytonutrients. Plus, they are high in the antioxidants and fiber your body needs to reduce your cancer risk.

Recent research suggests that fiber also may lower levels of C-reactive protein CRP , a protein in the blood that signals inflammation. The American Institute for Cancer Research recommends filling at least two-thirds of your plate with non-starchy vegetables, whole grains and fruit.

Fill the remaining one-third or less with lean protein or plant-based protein. Processed foods are lower in nutrients and higher in refined sugars, flours and unhealthy fats. Eating the right dietary fats is important for reducing inflammation.

Omega-3 fatty acids can help protect your body from chronic inflammation. On the other hand, omega-6 fatty acids increase inflammation. Eating too much red meat , like pork, beef, lamb, deer and buffalo, can increase your cancer risk. Try to limit red meat to 18 oz. or less a week.

Crawfofd suggests replacing red meat with these high-protein foods to help reduce chronic inflammation. Fermented foods, also known as probiotics , can help reduce inflammation.

To get the most health perks, eat at least one small serving of a fermented food each day. My Chart. Donate Today.

Acetylsalicylic acid ASA , also known as aspirin, is one of the most widely used drugs in the world, particularly for prevention of cardiovascular diseases The strongest beneficial effect has been found in esophageal adenocarcinoma, colorectal and stomach cancers and a smaller effect was observed in breast, lung, and prostate cancers No benefit was found for hematopoietic malignancies, pancreatic and endometrial cancer Increased expression of Cox2 and its major metabolite prostaglandin E2 PGE2 has been observed in many different types of cancer in which they enhance angiogenesis, apoptosis resistance, tumor growth, and metastasis Recent studies show that epigenetic modifications may also be involved in the chemopreventive actions of ASA, leading to suppressed histone deacetylase HDAC activity and increased H3K27 acetylation which results in reduced expression of iNos , Tnf , and Il6 Nevertheless, long-term NSAID administration can result in side effects including renal failure and gastrointestinal GI symptoms including mucosal lesions, bleeding, peptic ulcer, and intestinal inflammation which causes perforation and strictures in small and large intestines Such adverse effects may actually increase cancer risk.

Furthermore, NSAID intake increases the risk of deep vein thrombosis and its potentially life-threatening complications of pulmonary embolism, myocardial infarction, and stroke Several selective COX2 inhibitors that impair tumor growth and metastasis celecoxib, rofecoxib, valdecoxib, apricoxib, etoricoxib, and lumiracoxib were approved for marketing, but later withdrawn mostly due to increased risk of thromboembolic events.

Celecoxib is the only selective COX2 inhibitor that is still available in the United States and Europe Combining COX2 inhibitors with 5-LOX inhibitors can block synthesis of both prostaglandins and leukotrienes, resulting in reduced gastrointestinal toxicity In this context, the herbal medicines including the natural hydro-alcoholic extract of Cordia myxa fruit is considerably effective in treatment of acute inflammation in rats, and the active ingredients of its seeds, such as alpha-amyrins, have anticancer and anti-inflammatory activities by inhibiting COX2 and 5-LOX Corticosteroids, most commonly used as anti-emetic drugs that prevent chemotherapy-induced nausea and vomiting, are the most effective anti-inflammatory drugs for many chronic inflammatory diseases and were shown to have anticancer activity For example, pretreatment with dexamethasone increased effectiveness of chemotherapy in xenograft or syngeneic experimental tumor models of glioma, breast, lung, and colon cancers Dietary consumption of DEX has a chemopreventive effect in mice exposed to tobacco smoke, leading to decreased lung tumor incidence Recent studies had shown that DEX in combination with carfilzomib and lenalidomide, significantly improved progression-free survival of patients with relapsed multiple myeloma ref.

gov number, NCT In contrast high-dose inhaled ICS and oral corticosteroid OCS treatment, used to reduce local and systemic inflammation in patients with asthma and chronic obstructive pulmonary disease COPD , was found to increase the risk of squamous lung cell carcinoma in men Statins are a family of drugs that lower blood cholesterol concentration by blocking the 3-hydroxymethylglutaryl coenzyme A HMG-CoA reductase, which results in impaired cholesterol synthesis and by enhancing cholesterol clearance from the circulation In addition to its cholesterol-lowering effects statins also have anti-inflammatory properties 87 , which makes them powerful agents in prevention of atherosclerosis and resulting in life-threatening conditions, heart attack, and stroke.

Statins are able of reducing systemic proinflammatory cytokine and C-reactive protein CRP levels and macrophage infiltration 88, By exerting anti-inflammatory and other effects, statins also reduce the risk of development of several cancer types including colorectal cancer, HCC, and breast cancer 90— Metformin, a drug used for treatment of type 2 diabetes mellitus, was found to be associated with decreased incidence of a variety of cancer types including colon, breast, lung, prostate, ovarian, and pancreatic cancers Its antineoplastic effect is mediated through activation of the AMPK pathway, which counteracts the protumorigenic effect of hyperinsulinemia, the reduction of systemic glucose concentration, which counteracts Warburg effect and through its anti-inflammatory properties TAMs can generally promote cancer cell proliferation, stimulate tumor angiogenesis and extracellular matrix breakdown, suppress antitumor immune responses, and enhance tumor invasion and metastasis Their recruitment into the tumor microenvironment from the blood stream is primarily regulated by cytokines, chemokines, and growth factors that are derived from tumor and stromal cells.

The tumor-derived C-C chemokine ligand 2 CCL2 , acting via its receptor C-C chemokine receptor 2 CCR2 , is a direct mediator of monocyte recruitment into primary tumors TAMs are classified as either classically activated M1 or alternatively activated M2 macrophages The T H 1 cytokine IFNγ and LPS are the major inducers of the M1 phenotype, whereas T H 2 cytokines, such as IL4, IL10, and IL, stimulate M2 polarization During the course of tumor development, the TAM phenotype is modulated by different factors in the tumor microenvironment and it changes from the M1 to the M2 phenotype, which is claimed to have stronger tumor-promoting properties M2 macrophages are associated with poor prognosis in many different cancer types and can promote cell-cycle progression and angiogenesis while inhibiting apoptosis In fact, M1 and M2 characteristics often coexist within the same cell, and there is a broad variety of macrophage subtypes between the M1 and M2 poles Furthermore, the most potent tumor-promoting cytokines, such as IL6, TNF, IL1, and IL23 are considered as M1 cytokines Because of their important role in linking inflammation and cancer, the targeting of TAM recruitment and differentiation provides an opportunity for cancer prevention and treatment.

Depletion of CCL2 with a neutralizing antibody prevents monocyte recruitment to the primary tumor site and reduces pulmonary metastasis of human breast cancer cells A human anti-CCL2 antibody, CNTO , showed preliminary antitumor activity in patients while being well tolerated Blockade of CCR2 with small-molecule antagonist showed antitumor activity in pancreatic cancer in animal studies and this strategy is now being tested in clinical trials ClinicalTrials.

gov Identifier: NCT Trabectedin, a DNA-binding drug approved in Europe for the treatment of soft tissue sarcoma, has been shown to selectively deplete mononuclear phagocytes in vivo , including TAMs Rapidly growing tumors often outgrow their blood supply, which results in formation of hypoxic areas with TAM accumulation Binding of semaphorin 3A to its receptor neuropilin-1 Nrp1 recruits TAMs toward the hypoxic area where they adopt the M2 phenotype and release proangiogenic factors Inhibition of Nrp1 reduced TAM migration and prevented their phenotypic switch to M2-like immunosuppressive cells with angiogenic activity making it an interesting target for anticancer therapy.

Several therapies convert macrophages from an M2 to an M1 phenotype Tasquinimod is a small-molecule compound that reduces the immunosuppressive potential of the tumor microenvironment A recent study demonstrated its ability to induce a shift of imunosuppresive M2 to proinflammatory M1 macrophages in colon and breast cancer models Colony-stimulating factor 1 CSF-1 and its receptor, CSF-1R, mediate migration, differentiation, and survival of macrophages Treatment with anti-CSF-1R antibody resulted in TAM depletion in several tumor types in vitro and in vivo and a clinical benefit for patients with diffuse-type giant cell tumors TAMs express significant amounts of COX2 and the selective COX2 inhibitor celecoxib was shown to switch their phenotypic characteristics from M2- to M1-like, which was followed by a reduction in number of colon polyps in an animal study on colon cancer Recent studies had shown that decreasing TAM survival, by the targeting folate receptor-β FR-β , a marker for the M2-polarized phenotype, is another promising strategy against cancer, in an experimental glioma model NF-κB and STAT3 are 2 critical transcription factors that are activated in many types of cancers 8, , The STAT proteins family, which includes 7 members, regulates multiple processes related to cellular proliferation, survival, and angiogenesis Among the different STATs, the one most important for cancer is STAT3, whose activity is stimulated by IL6, IL11 and other members of their cytokine family, as well as different growth factors In HCC and liver adenomas, STAT3 activity is stimulated by various oncogenic mutations , but more often than not, STAT3 is maintained in an activated state due to elevated production of IL6 and other cytokines STAT3 signaling also has important roles in tumor microenvironment where it promotes ILmediated protumorigenic immune responses while inhibiting expression of antitumorigenic IL12 Inhibition or ablation of STAT3 can mediate tumor regression Therefore, inhibition of STAT3 provides a rational strategy to block carcinogenesis at an early stage and induce regression of established tumors.

There are 3 major approaches to inhibit STAT3 signaling: inhibition of tyrosine kinases, such as JAK1 and 2, that are responsible for STAT3 activation AG- , ruxolitinib, etc.

Among tyrosine kinase inhibitors some are rather specific for JAK2 family members, whereas others inhibit several different kinases that lead to STAT3 activation Currently, these drugs are being evaluated as neoadjuvants in several types of cancer, including pediatric refractory or recurrent solid tumors, hematologic malignancies , pancreatic adenocarcinoma, triple-negative breast cancer, urothelial cancer, multiple myeloma, acute myeloid leukemia, myelodysplastic syndrome lymphoma ClinicalTrials.

Despite their clinical approval and marketing in myelofibrosis and rheumatoid arthritis, JAK inhibitors exert rather serious side effects including anemia, thromobocytopenia, headaches, nausea, and neurotoxicity However, more selective inhibitors with fewer side effects are currently being developed.

Yet, it is doubtful whether such agents will ever find use in cancer prevention. Targeting STAT3 proinflammatory pathway. Schematic representation of the major targetable events during STAT3 activation, and the corresponding compounds with cancer-preventive properties.

The NF-κB pathway is constitutively activated in many cancers, both in malignant cells and in components of the tumor microenvironment NF-κB activation in malignant cells increases the expression of genes, whose products promote cell survival and proliferation, whereas NF-κB activation in components of the tumor stroma increases expression of inflammatory cytokines and growth factors 8, NF-κB activation also promotes epithelial-to-mesenchymal transition EMT and tumor angiogenesis Although NF-κB activation plays a major role in the induction of inflammation, long-term and extensive inhibition of NF-κB can result in profound inflammation due to enhanced production of IL1β upon activation of the NLRP3 inflammasome This can result in severe neutrophilia , a serious condition that led to termination of any further clinical development.

Nonetheless, the cancer prevention literature is full of reports using natural anti-inflammatory agents, including curcumin, resveratrol, ursolic acid, capsaicin, silibinin, silymarin, guggulsterone, and plumbagin, all of which are claimed to act as NF-κB inhibitors — Most likely, however, these are rather mild and nonspecific NF-κB inhibitors, most of which affect multiple targets, including STAT3.

Because of their rather mild effects, such agents, many of which are used as nutritional supplements, can be used in cancer prevention , but it is doubtful whether they will ever find use as anticancer drugs.

The major problem associated with NF-κB inhibition is enhanced activation of the NLRP3 inflammasome The inflammasome is a multimeric complex consisting of the intracellular Nod-like receptors NLR and the adaptor protein ASC that serves as a platform for activation of caspase-1 Inflammasomes have a crucial role in host defense against infection as well as various autoinflammatory conditions Upon NLR oligomerization and subsequent interaction between the adaptor protein ASC and the CARD domain, caspase-1—mediated processing results in production of the proinflammatory cytokines IL1β and IL18 or a rapid inflammatory form of cell death called pyroptosis NF-κB is the first signal that primes NLR and pro-IL1β expression , but persistent NF-κB activation is also responsible for dysregulated NLRP3 inflammasome activation by inducing the mitophagic clearance of damaged mitochondria The role of NLR-containing inflammasomes in mediating cancer initiation and progression by creating a proinflammatory microenvironment for inducing malignant transformation and suppression of local immunity caused by NK or T cells open the way for novel strategy in cancer prevention.

Between the 22 NLRs in the human and the 34 NLRs in the mouse genome, NLRP3 NLR family, pyrin domain containing 3 is the best characterized.

The NLRP3 inflammasome plays an important role in several inflammatory disorders including IBD , and its activation is negatively regulated by selective mitochondrial autophagy mitophagy; ref. During tumorigenesis, IL6 has served detrimental effects including stimulation of cell survival and proliferation, regulation of stem cell renewal, and induction of angiogenesis.

A humanized anti-IL6 receptor monoclonal antibody toclizumab is an FDA-approved immunosuppressive drug that blocks IL6 signaling. It is used in the treatment of rheumatoid arthritis and systemic juvenile idiopathic arthritis Chimeric monoclonal antibody siltuximab that binds IL6 showed good tolerance in patients with cancer in a phase I clinical trial and is currently investigated for the treatment of several tumor types including prostate cancer and metastatic renal cell cancer Long-term treatment with anti—IL6-blocking antibody was associated with very few side effects in a mouse model of pancreatic cancer prevention Thus, IL6 emerges as a promising potential target for cancer prevention.

The proinflammatory chemokine IL8 and its receptors CXCR1 and CXCR2 were also linked to cancer and inflammation Another proinflammatory cytokine with reported role in promoting tumorigenesis is IL17A TGFβ and IL6 are needed for the differentiation and IL23 for the maintenance of T H 17 cells that produce IL17A.

Antibodies against IL17A ixekizumab and secukinumab and its receptor IL17AR brodalumab are in clinical trials for chronic inflammatory conditions and autoimmune diseases and an anti-IL23 antibody ustekinumab was FDA-approved for the treatment of psoriatic arthritis However, preventive application of such drugs should take in account reported antitumor effects of IL17 in established tumors as well as its role in autoimmunity.

Vaccines that protect against certain viral infection play important role in cancer prevention. For instance, hepatitis B virus HBV is a major cause of HCC whose impact has been dramatically reduced in all countries due to massive vaccination efforts The most effective way to prevent HBV infection and reduce HCC development is vaccination The prophylactic vaccine that is currently in use is generated by recombinant DNA technology and contains HBsAg protein and adjuvants.

For patients who have already been infected by HBV and developed chronic hepatitis, secondary prevention becomes more important. Currently, antiviral drugs used in patients with chronic hepatitis B include the immunomodulator PEGylated IFNα and oral nucleos t ide analogues IFNs activate various IRF family members that regulate transcription of numerous targets, including genes involved in control of viral mRNA translation or degradation However, the mechanism of IFNα-mediated cell protection against viral infection is not fully understood.

In addition to HBV, hepatitis C virus HCV is another important cause of HCC, against which there is no preventive vaccine However, the recent development of highly effective anti-HCV drugs will lead to major decrease in HCV-induced HCC Human papilloma virus HPV is a major cause of cervical intraepithelial neoplasia that can progress to invasive cervical cancer Recently, we have witnessed the development of an effective HPV vaccine that if properly distributed amongst young adults will lead to a major decrease in the impact of cervical and other urogenital cancers.

In summary, vaccination against cancer-causing viruses is one of the most effective and economical ways to reduce the toll of several inflammation-related cancers.

Liquid chromatography-coupled mass spectrometry preventipn of glutathione conjugates Hydration strategies for athletes oxygenated polyunsaturated fatty acids. Lipoxins and aspirin-triggered epi-lipoxins are the first lipid mediators of endogenous anti-inflammation and resolution. This paper provides genetic evidence supporting the idea that the success of anticancer chemotherapies depends on the immune system, in human breast cancer and colorectal carcinoma. Monocytes have been found to migrate to the inflammatory site following CCL2 gradients orchestrated by vascular endothelial cells in response to PAMPs.
Risk Factors: Chronic Inflammation - NCI Excessive alcohol consumption is also a major etiologic factor in chronic pancreatitis and pancreatic ductal adenocarcinoma PDAC; refs. Recommendations made by the Joslin Diabetes Research Center at Harvard Medical School for the treatment of obesity stated that omega-3 fatty acids should be taken twice a week using food sources such as fatty fish Lee, M. When combined with cytotoxic chemotherapeutic agents, fasting and caloric-restriction mimetics modify the tumor immune-cell infiltrate. The impact of anti-inflammatory agents on the outcome of patients with colorectal cancer. This paper provides an excellent synthesis of the major rules governing the relationship between oncogenesis and anticancer immunosurveillance.
This page adheres to our Herbal heart health and editorial Inflammation and cancer prevention and anc. Correcting sports nutrition misconceptions is often preventiob double-edged sword. German pathologist Rudolf Inflammaion first noted the potential tie in the 19th century. Inflammation is a normal physiological process that occurs in response to infection or injury. The immune system releases white blood cells and chemicals to fight an infection or repair damaged tissue. Then, after the infection goes away or the tissue heals, the inflammatory process shuts off as part of a process known as acute inflammation. Inflammation and cancer prevention
