Exercise prevents cancer

March 3, 2010 — Zenfix

Exercise in prevention and management of cancer.

OPINION STATEMENT: Regular and vigorous physical exercise has been scientifically established as providing strong preventative medicine against cancer with the potential to reduce incidence by 40%. The effect is strongest for breast and colorectal cancer; however, evidence is accumulating for the protective influence on prostate cancer, although predominantly for more advanced disease and in older men…

New Cancers in Cancer Survivors

February 25, 2010 — Zenfix

Subsequent malignant neoplasms in cancer survivors.

Although cancer survivors now comprise about 3.5% of the population, subsequent malignancies among this high-risk group account for about 16% (or 1 in 6) of all cancer incidence.

Garlic and cancer prevention

February 22, 2010 — Zenfix

Garlic intake and cancer risk: an analysis using the Food and Drug Administration’s evidence-based review system for the scientific evaluation of health claims.

A literature search found 19 human studies that were reviewed. Garlic in the diet did not reduce the risk of gastric, breast, lung, or endometrial cancer.
There is very limited evidence for a reduced risk of colon, prostate, esophageal, larynx, oral, ovary, or renal cell cancers.

Vitamin D and Cancer Prevention

February 19, 2010 — Zenfix

Vitamin D: Considerations in the Continued Development as an Agent for Cancer Prevention and Therapy.

Epidemiologic studies show that people with lower serum vitamin D levels have a higher risk of cancers. Will giving vitamin D supplements reduce the risk of cancer?

Cancer prevention with phytochemicals

February 19, 2010 — Zenfix

Dietary chemopreventive phytochemicals: too little or too much?

Some dietary phytochemicals seem to offer protection in an exposure-related manner and many molecular targets and signaling pathways affected by phytochemicals have been discovered.

Inactivity and Survivors of Childhood Cancer

February 16, 2010 — Zenfix

Predictors of inactive lifestyle among adult survivors of childhood cancer.

This study looked at the physical activity of 9301 adult survivors of childhood cancer and 2886 siblings. Adult survivors of childhood cancer survivors were less active than their siblings.

Green tea cancer prevention

February 7, 2010 — Zenfix

Green tea (Camellia sinensis) for the prevention of cancer

Green tea contains catechins which are powerful antioxidants that may prevent cancer. This Cochrane review looked at 51 studies that included:

  • cancer of the digestive tract,
  • breast cancer,
  • prostate cancer,
  • lung cancer,
  • ovarian cancer,
  • oral cancer.

Drinking 3 to 5 cups of green tea per day is safe and provides 250 mg of catechins per day.
The author concludes that there is insufficient evidence for green tea consumption preventing cancer.

Aspirin and NSAIDs for cancer prevention

February 4, 2010 — Zenfix

Aspirin and non-steroidal anti-inflammatory drugs for cancer prevention: an international consensus statement

Aspirin and non-steroidal anti-inflammatory drugs (NSAIDs) could prevent colorectal cancer and may probably prevent other cancers. Research is focusing on breast, prostate, lung, stomach, and oesophageal cancer.

Anti-inflammatory Effects of Fruit and Vegetables

January 29, 2010 — Zenfix

Anti-inflammatory Effects of Plant-based Foods and of their Constituents.

Epidemiological data suggest that dietary patterns strongly affect inflammatory processes. Primarily the intake of fruit and vegetables as well as of whole wheat is inversely associated with the risk of inflammation.

Diet and cancer chemoprevention

December 27, 2009 — Zenfix

Dietary factors and cancer chemoprevention: an overview of obesity-related malignancies.

“Currently, obesity-related malignancies, e.g., cancers of the breast, prostate and colon are the leading cancers in the industrialized societies.”

This review looks at cancer prevention studies in selected cancers associated with obesity:

  • Prostate cancer
  • Breast cancer
  • Endometrial cancer
  • Kidney cancer
  • Esophageal adenocarcinoma
  • Colon cancer

And on foods that have anti-obesity and anti-cancer effects:

  • Garlic
  • Fenugreek
  • Green tea
  • Soy
  • Bitter melon
  • Plant defense molecules
  • Fish

Impact of Nutrition and Exercise on Cancer Survival

December 18, 2009 — Zenfix

Impact of nutrition and exercise on cancer survival.

Observational data strongly indicate that obesity, weight gain, and physical inactivity are adverse prognostic factors, although data on diet or supplement use in relation to cancer survival are more limited and inconsistent.
