Saturday July 30, 2011 (foodconsumer.org) ? Eating red meat may boost risk for breast cancer, a new study in the May 3, 2011 issue of Breast Cancer Research and Treatment suggests.

Z. Fu and colleagues from Vanderbilt Epidemiology Center conducted in Nashville Tennessee the study of 2,386 breast cancer cases and 1,703 healthy women as controls and found eating red meat was associated with increased risk for breast cancer.

Fu et al. found the association was particularly significant for well-done red meat. Women whose intake of well-done red meat was in the highest quartile were 50 percent more likely to be diagnosed with breast cancer, compared with those whose intake was in the lowest quartile.

The associations were stronger in postmenopausal women than premenopausal women.

Intake of mutagens formed during the cooking of red meat such as 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline and 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline was also correlated with elevated breast cancer risk in postmenopausal women.

Breast cancer is diagnosed in about 175,000 women in the United States each year and the disease and its complications kill about 5000 annually in the country.

Breast cancer is largely a preventable disease, some experts believe, and a healthy lifestyle including a healthy diet is considered important in preventing the disease.

Red meat has been linked with other types of cancer including pancreatic cancer, stomach cancer, lymphoma, lung cancer, prostate cancer, esophageal cancer, bladder cancer, colorectal cancer, ovarian cancer and endometrial cancer among other diseases.

Mutagens formed during the cooking are only one cause for the increase in the risk of breast cancer. Iron in hemoglobins of red meat has also linked with elevated cancer risk.

Red meat refers to mainly three types of meat, beef, pork and lamb.
