3. Eat more cabbage
A recent study conducted at the Harvard School of Public Health found that women who ate about four servings of vegetables a day minimized their chances of developing hormone receptor–negative breast cancer by 18 percent.
Other research presented at the American Association for Cancer Research Annual Meeting in April 2012 revealed that women with breast cancer who ate the highest amount of cruciferous vegetables per day had a 62 percent reduced risk of breast cancer mortality and a 35 percent reduced risk of recurrence.
"Cruciferous vegetables — such as cauliflower, cabbage, bok choy, turnip greens and broccoli — contain high amounts of isothiocyanates and indoles, phytochemicals that appear to have a protective effect against some types of cancer," says researcher Seungyoun Jung, Sc.D., of Brigham and Women's Hospital in Boston. "They also contain significant amounts of vitamin C, carotenoids and polyphenols, which have antioxidant properties."
4. Drink alcohol sparingly
That would be no more than one drink per day, according to the American Cancer Society guidelines on nutrition and physical activity for cancer prevention. One analysis of more than 40 studies found that just two drinks a day may raise your odds by 21 percent. If you already have the disease, one recent study showed that regular alcohol consumption (half a drink or more per day) increased recurrence in postmenopausal women by 19 percent.
"A possible reason is that alcohol consumption has been shown to elevate circulating estrogen levels in postmenopausal women," says lead author Marilyn Kwan, Ph.D., a research scientist at Kaiser Permanente Northern California in Oakland. "If you're a breast cancer survivor, talk to your doctor and consider limiting your intake to no more than a half drink per day or no more than three to four drinks per week," says Kwan.
5. Get up and go!
Walk. Garden. Vacuum. The latest research shows that any physical activity protects against breast cancer. And news that tops that: It's never too late to start. A new study finds that even women who didn't start exercising until after menopause showed diminished risk.
"This is particularly encouraging given the late age of onset for the disease," says study author Lauren McCullough, of the University of North Carolina. Women who exercised at any intensity for 10 to 19 hours per week reaped the greatest benefit; they had about a 30 percent reduced risk. That breaks down to about 90 minutes a day, which seems like a lot, until you realize that all activity counts.
"Just take note of how long it takes to perform the activities you're already doing every day, and build on that," McCullough says. "If you know you spend 15 minutes doing housework and another half hour in the garden, be sure to walk your dog for 45 minutes." Just don't use exercise as an excuse to gain weight. When researchers looked at the combined effects of physical activity, weight gain and body size, they found that active women who packed on pounds — particularly after menopause — had an increased risk of developing breast cancer. The bottom line: Weight gain can quash the beneficial effects of exercise, so keep your weight in check.
