Chronic inflammation and cancer
Dr. John Campbell・2 minutes read
Cancer development is a complex process involving mutations, chronic inflammation, viral infections, and immune system responses, with factors like obesity, hormonal aspects, and lifestyle choices influencing cancer risks. Understanding the interplay between these various factors is crucial in comprehending cancer development and progression, highlighting the importance of immune system modulation, chronic inflammation suppression, and healthy lifestyle choices in reducing cancer risks.
Insights
- Chronic inflammation is a significant precursor to over 90% of cancers, affecting the immune system's ability to detect and eliminate mutations, highlighting the crucial role of inflammation in cancer development.
- Boosting T-cell response and reducing chronic inflammation can significantly lower cancer risk, with promising treatments like Mycobacterium vaccae showing potential in modulating the immune system to combat cancer.

Viral Infections and Cancer Development: Insights
- Professor Angus da Professor is a well-known oncologist and fellow of various medical colleges in the UK and Australia.
- Cancer is a disorder of cell growth and differentiation where cells escape their programming, leading to uncontrolled growth.
- Cancer development is a regulated process involving mutations that delay cell death, allowing for further mutations to occur.
- Viruses, particularly retroviruses, can cause cancer by facilitating mutations in cells, leading to malignancies.
- Hepatitis B and C viruses are linked to liver cancer, with chronic inflammation and angiogenesis playing crucial roles in cancer development.
- Human papillomavirus is associated with various cancers, including mouth, throat, and esophageal cancers, due to chronic inflammation in mucosal tissues.
- Epstein-Barr virus and herpes viruses like HHV6 are also implicated in driving lymphomas and sarcomas by evading the immune system.
- Cancer development is influenced by chronic immune suppression and angiogenesis in the tumor microenvironment.
- The balance between immune suppression and angiogenesis is debated among scientists, with some emphasizing the role of angiogenesis in enabling cancer growth.
- Understanding the interplay between immune suppression, angiogenesis, and viral infections is crucial in comprehending cancer development and progression.

Chronic Inflammation: Cancer Risk and Treatment Options
- Chronic immune suppression and chronic angiogenesis are caused by chronic inflammation, which viruses exploit.
- Lung cancer often follows decades of chronic bronchitis, showcasing chronic inflammation's role in cancer development.
- Colorectal cancer is 50 times more common in patients with ulcerative colitis, a chronic inflammatory condition.
- Polyps, if left to grow, can mutate into cancer, especially in individuals with a familial predisposition.
- Polyps are classified as inflammatory lesions and can turn malignant if not removed promptly.
- Chronic inflammation is a significant precursor to over 90% of cancers, affecting the immune system's ability to detect and eliminate mutations.
- Chronic inflammation suppresses T-cells, allowing mutations to survive and progress into cancer over decades.
- Boosting T-cell response and reducing chronic inflammation can significantly lower cancer risk.
- Mycobacterium vaccae (M. vaccae) boosts T-cell response and suppresses chronic inflammation, showing promise in cancer treatment.
- Long-term follow-up studies suggest that early immune system modulation, like with BCG vaccine, may reduce the incidence of heart disease and cancer later in life.

"Viral DNA and RNA: Cancer Risks and Treatments"
- BCG vaccines can cause lymph nodes and lower TB levels, easily treatable with a short course of reformation.
- Herpes and Hepatitis B viruses are DNA viruses associated with cancer in humans.
- Retroviruses are RNA viruses that code into DNA, making them dangerous.
- Messenger RNA viruses are risky due to their ability to reprogram DNA, posing a danger.
- Reverse transcriptase is essential for RNA to DNA conversion, crucial in treating HIV.
- Endogenous retroviruses in human cells can be activated by other viruses, potentially leading to diseases like multiple sclerosis.
- Chronic inflammation can lead to cancer development by disrupting cellular balance.
- Aspirin, an anti-inflammatory, can reduce the risk of colon cancer and heart attacks.
- Obesity is linked to chronic inflammation, increasing the risk of various cancers due to increased cell numbers and inflammatory factors.
- Bigger individuals, genetically predisposed or obese, have a higher likelihood of developing cancer due to increased cell numbers and random mutations.

"Health Factors Influencing Cancer Risks"
- Sailors adapted to long voyages without food by storing extra capacity, leading to obesity-related issues interfering with metabolic pathways.
- Obesity is linked to common vascular diseases like diabetes and various cancers such as lung, bowel, prostate, breast, pancreas, esophagus, liver, and bladder.
- Hormonal aspects play a role in breast and prostate cancers, influenced by chronic inflammation and immune status.
- Physical activity, particularly in mice studies, shows a significant reduction in tumor development with regular exercise.
- Sun exposure and ultraviolet radiation induce chronic inflammation, affecting skin health and potentially leading to melanoma.
- Vitamin D deficiency is associated with chronic inflammation, autoimmune diseases, and low levels are linked to various cancers.
- Radiation exposure, like x-rays, can damage genetic material, leading to cancer, with dose and time being critical factors.
- Iatrogenic causes of cancer, like medical treatments and immunosuppression post-transplants, increase cancer risks.
- A healthy diet, high in fiber and essential nutrients like iodine, is crucial for maintaining a healthy immune system and preventing cancer.
- Moderate alcohol consumption, particularly red wine with its anti-inflammatory properties, can be beneficial, but excess alcohol intake leads to chronic inflammation and increased cancer risks.

Health Risks of Smoking, Asbestos, and Pollution
- Richard Doll conducted surveys showing smoking caused lung cancer, despite industry resistance.
- Asbestos exposure can lead to mesothelioma after at least 40 years, causing chronic inflammation.
- Treatment with IMM, a mycobacteria vaccine, and vitamin D has shown positive results in mesothelioma patients.
- Randomized trials' credibility has been questioned, impacting medical research outcomes.
- Air pollution, particularly microparticulates like diesel fumes, poses health risks, emphasizing the need for cleaner technologies.
