How to prevent breast cancer?

Eat less fats

High-fat ( especially animal fats and trans fats) diet may increase the risk of breast cancer.  Studies found that excessive fat intake will produce more free radicals and stimulate cell division and deterioration.

High-fat diet will also produce chemical in the intestine. Intestinal bacteria will transform it into carcinogenic estrogen which is then stored in the fatty tissue of the breast and then develops into cancer.

Harvard University had conducted a survey on more than 120,000 women. It was found that the mortality rate for breast cancer patients would increase 70% if the patient is a high fat intaker before.

Not all fats are bad. A study in Canada found that daily use flaxseed oil can help reduce the risk of breast cancer.

Eat more fish

Although women should eat less animal fat, they can eat more fish, especially in deep water fish such as tuna, salmon, cod and sardines . That's why Eskimo women have low incidence of suffering from breast cancer as they eat a lot of deep-water fish.

Take high-fiber diet

Eat more vegetables can reduce the incidence of breast cancer. Increased consumption of high fiber foods helps stimulate gastrointestinal motility, increasing the rate of food through the intestines . In addition, vegetables, fruits, grains , seeds , nuts and beans contain phytochemicals such as polyphenols, which can protect cells and inhibit cancer cell growth.

Drink tea and soy milk

Green tea contains antioxidants and anti-cancer polyphenols while, according to the studies from the American Association for Cancer Research, soy milk can reduce the body producing hormones estrogen and progesterone. Excessive concentration of these would increase the risk of breast cancer.

Other causes of breast cancer include frequent contact with environmental toxins such as pesticides and cancer gene mutation.

BRCA1 and BRCA2 are human genes important in inhibiting cancer. Medical profession has found that BRCA1 and BRCA2 gene mutation will increase the risk of cancer. Women with BRCA1 gene mutation have 51-75% risk of breast cancer while 22-51 % of the chance suffering from ovarian cancer. For the BRCA2 gene mutation, the chances are 33-54 % and 4-18 % respectively.
