Stay lean
One of the most important ways to lower breast cancer risk is to avoid gaining weight. If you’re already overweight, trimming down before age 45 will lower the chance of developing breast cancer post menopause. Exercise can help to lower the levels of hormones which are related to breast cancer. Studies involving more than 100,000 women showed that those who exercised regularly were at less risk for breast cancer.

Moderation
Even though the correlation between diet and breast cancer prevention has been inconclusive, there has been a lot of hard evidence relating it to alcohol consumption. There has been much information about the positive benefits of moderate alcohol intake and heart disease- which kills far more women than breast cancer. However, if you are have other risk factors for breast cancer or a family history of it you may want to avoid it altogether.

Forget supplements
Soy foods are very common in eastern countries like China and Japan, and those countries also have some of the lowest breast cancer rates in the entire world. Soy foods like tofu have been shown to slightly lower risk for breast cancer, but soy supplements can have the exact opposite reaction. There are agents present in these supplements that can act like estrogen in the body, and cause cell changes that increase risk for cancer.

Fruits and Veggies
There hasn’t been much solid evidence linking diet to cancer risk, but there are facts that support the fact that maintaining a healthy weight (which can be achieved by eating a diet that is lower in calories) can. Studies from UC San Diego reveal that women who eat at least 5 servings of vegetables or fruits daily have cut their risk of breast cancer related death by half.

Fish oil
Omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid are known primarily for lowering harmful blood fats called triglycerides. They can also help to mildly lower blood pressure. A daily dose of 1 gram can help with blood pressure, but 2-4 grams is recommended for lowering triglycerides. If you are already taking a blood thinner, talk to your doctor before starting to take fish oil as it can increase bleeding risk in these situations.

CoQ10
Typically combined with niacin (vitamin B-3), CoQ10 can help to minimize side effects from cholesterol lowering statin drugs like muscle weakness. It can also help to enhance the energy production in cells, and inhibit blood clot formation. Typical dose is 50-100 milligrams daily.

Red yeast rice
Available in tablet, capsule, powder, and liquid forms, this is an extract of red yeast that is fermented onto rice. It has long been used by the Chinese, and it can mimic the same actions as statin drugs for lowering cholesterol. Average dose is 600 milligrams, twice a day, but can be enhanced with combined with naturally occurring plant sterols. These can be found in small amounts in fruits and vegetables, but also in supplement form. Add 400 milligrams of these for best benefits.

Lycopene
Found in tomatoes, watermelon, pink grapefruit, red bell peppers, and papaya, this phytochemical can be helpful in lowering blood pressure. Research has proven it can lower systolic (top) blood pressure by 10 points, and diastolic (bottom) blood pressure by up to 4 points. It is a potent antioxidant, and has even been thought to have cancer preventing properties, but they have not been proven. 10 milligrams daily is the average dose.
