Diet and nutrition can play a significant role in the chances of developing breast cancer, especially if you have a family history of the disease.
Foods that may help to prevent or lessen the risks
Use healthy fats: Monounsaturated fats found in a high quality, extra virgin olive oil, and polyunsaturated omega-3 fats from freshly ground flaxseed and oily fish such as wild Alaskan salmon and sardines may help reduce your risk of developing breast cancer.
Include whole soy products in your diet. Soy foods contain many cancer-protective substances, including isoflavones. Try to eat one to two servings of whole soy-based foods a day, such as organic edamame, tofu or tempeh.
Eat more fruits and vegetables! Especially cruciferous vegetables such as broccoli, bok choy and cauliflower, which contain many different cancer-protective phytonutrients.
Foods that may help increase your risk
Eating too much fat. Keep your dietary fat content moderate – below 25 percent of your daily calories is ideal.
Consuming polyunsaturated omega-6 fats (including many vegetable oils), and hydrogenated oils (margarines and vegetable shortenings) can all increase cancer risks. Minimize consumption of all.
Drinking alcohol. Even in modest amounts, alcohol consumption is associated with an increased risk of breast cancer.
A daily intake of conventionally raised meat, poultry, eggs and dairy products. These may contain hormone residues that influence estrogen metabolism. Replace with organic, hormone-free versions.
