Healthy Weight Loss May Also Cut Your Cancer Risk

TUESDAY, May 1 (HealthDay News) -- Moderate weight loss reduces levels of inflammation that have been tied to certain cancers, at least in postmenopausal women, a new study suggests.

According to the findings, older women who lost at least 5 percent of their body weight through diet alone or diet plus exercise showed significant reductions in key inflammatory blood markers such as C-reactive protein and interleukin-6.

In addition to risk for heart disease, elevated levels of these markers have also been associated with increased risk for several cancers, including breast, colon, lung and endometrial cancer.

The findings appear May 1 in the journal Cancer Research.

"Our findings support weight loss through calorie reduction and increased exercise as a means for reducing inflammatory biomarkers and thereby potentially reducing cancer risk in overweight and obese postmenopausal women," said researchers led by Dr. Anne McTiernan, director of the Prevention Center at the Fred Hutchinson Cancer Research Center, in Seattle.

Aiming to lose 10 percent of their body weight, the women were either placed on a calorie-restricted diet, asked to participate in moderate-to vigorous-aerobic exercise for 45 minutes a day for five days a week, or told to do both.
