Sit down to a colorful, crunch-tastic dinner. Studies show a 46 percent reduction in breast cancer among women who eat their veggies. Broccoli and its cruciferous cousins (such as brussel sprouts) — along with garlic, a great flavor-enhancer — fortify your defenses by removing carcinogens from your body.

Try veggie stir-fries, and check out restaurant salad bars. And if alcohol helps you relax, an occasional glass won't hurt. Just keep it to one drink per day; alcohol taxes the liver to reduce its efficacy in processing estrogen. Drinking with food mitigates liver exertion, so never imbibe on an empty stomach!
