Vegetarians Have Lower Cancer Risk
A 12-year study that followed over 60,000 Britons, half of whom were vegetarian, suggests that vegetarians had a lower risk of developing cancer than meat-eaters. The results showed that overall, vegetarians were 12 per cent less likely to develop cancer than meat eaters, while fish eaters were 18 per cent less likely (however fish eaters was also a smaller sample and potentially a less reliable statistic).

Vitamin C as a Potential Anti-Cancer Agent: Progress and Controversies
Read the rest of this page »
Vitamin C is commonly known to be essential to human health. However, specifically as it relates to cancer treatment, the value of vitamin C is debated and often considered a topic of scientific controversy. Cancer researchers have investigated various ways of administering high-dose vitamin C, including both orally and intravenously. Researchers have also examined different forms of vitamin C—ascorbic acid (AA) and dehydroascorbic acid (DHA)—which may well be a comparison of apples and oranges.
Cancer Statistics, 2009. Breast Cancer rates down due to reduced risk of HRT?
Each year, the American Cancer Society estimates the number of new cancer cases and deaths expected in the United States in the current year and compiles the most recent data on cancer incidence, mortality, and survival based on incidence data from the National Cancer Institute, Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Centre for Health Statistics. Incidence and death rates are standardized by age to the 2000 United States standard million population.

What Are the Preferred Methods of Detecting Breast Cancer – A Review
The most devastating loss of life from breast cancer impacts women between the ages of 30 and 50. For women between the ages of 40 and 44, breast cancer is the leading cause of death, according to the American Cancer Society. Yet the November 10, 2003 issue of the AMA journal, American Medical News, reports little evidence documenting that mammography saves lives from breast cancer for premenopausal women, which are many of the women who fall into these age ranges.

Green Tea Reduces Risk Of Gastric Cancer In Women Drinking > 5 Cups Per Day
Background: Previous experimental studies have suggested many possible anti-cancer mechanisms for green tea, but epidemiologic evidence for the effect of green tea consumption on gastric cancer risk is conflicting.
Objective: To examine the association between green tea consumption and gastric cancer.

Impact Of Antioxidant Supplementation On Chemotherapeutic Toxicity: A Systematic Review Of The Evidence From Randomized Controlled Trials.
Much debate has focused on whether antioxidants interfere with the efficacy of cancer chemotherapy. The objective of this study is to systematically review the randomized, controlled clinical trial evidence evaluating the effects of concurrent use of antioxidants with chemotherapy on toxic side effects.

Antioxidants And Other Nutrients Do Not Interfere With Chemotherapy Or Radiation Therapy And Can Increase Kill And Increase Survival, Part 1.
PURPOSE: Some in the oncology community contend that patients undergoing chemotherapy and/or radiation therapy should not use food supplement antioxidants and other nutrients. Oncologists at an influential oncology institution contended that antioxidants interfere with radiation and some chemotherapies because those modalities kill by generating free radicals that are neutralized by antioxidants, and that folic acid interferes with methotrexate. This is despite the common use of amifostine and dexrazoxane, 2 prescription antioxidants, during chemotherapy and/or radiation therapy.

An Herbal Extract Inhibits the Development of Pancreatic Cancer
Comment: An herb recently found to kill pancreatic cancer cells also appears to inhibit development of pancreatic cancer as a result of its anti-inflammatory properties, according to researchers from the Kimmel Cancer Center at Jefferson. The data were presented at the AACR 100th Annual Meeting 2009 in Denver.

Evidence-based decision making on micronutrients and chronic disease: long-term randomised controlled trials are not enough
Comment: Of course, everyone would agree that all persons should be encouraged to eat a good diet, but we are far from achieving this goal, especially among the poor. In most cases, a simple way to improve micronutrient status is to take an MVM. However, even if one eats an ideal diet and takes an MVM, some vitamins can remain below recommended concentrations in some subgroups. For example, the efficiency of absorption of vitamin B-12 decreases with age, and supplements containing more than the Recommended Dietary Allowance are needed to correct the deficiency. The ability of the skin to use ultraviolet light to synthesise vitamin D3 also decreases with age and is inefficient in dark-skinned people. Because dietary sources of vitamin D3 are not plentiful, supplements are recommended for those groups.

Low micronutrient intake may accelerate the degenerative diseases of aging through allocation of scarce micronutrients by triage
Inadequate dietary intakes of vitamins and minerals are widespread, most likely due to excessive consumption of energy-rich, micronutrient-poor, refined food. Inadequate intakes may result in chronic metabolic disruption, including mitochondrial decay. Deficiencies in many micronutrients cause DNA damage, such as chromosome breaks, in cultured human cells or in vivo. Some of these deficiencies also cause mitochondrial decay with oxidant leakage and cellular aging and are associated with late onset diseases such as cancer. I propose DNA damage and late onset disease are consequences of a triage allocation response to micronutrient scarcity.
