The risk of breast cancer increases when your mother, aunt, grandmother or sister are affected by cancer before age 50. If one's mother or sister you have cancer, your risk is twice than the average. When both are affected, the risk you got five times from the average. Approximately 20-30 percent of women affected by breast cancer have close relatives who are also diagnosed with the disease. About 70 percent of the remainder is more difficult to determine its risk factors. Diet, weight, smoking, drugs, etc. can affect breast cancer risk.
Here are 7 ways to prevent breast cancer by reducing risk factors beyond genetic talent:
In an experiment, researchers asked 1550 women aged 40-85 years about their exercise habits. The women who actively exercise have half the risk of breast cancer is lower than those with less exercise. Walk 30 minutes, five times a week can reduce breast cancer risk by 18 percent according to another study involving 74 thousand women aged 50 to 79 years.
2. Maintaining body weight
American Cancer Society had conducted a study involving 62 thousand women. The researchers found that the more weight gain since she was 18 years old, the greater the risk of breast cancer in the menopause. Those who gained weight to 30 pounds increased the risk twofold. Excess weight appears to increase estrogen, which supports the formation of cancer.
3. avoiding fat
There is a link between high consumption of unsaturated fats plural chain (corn oil, sunflower, etc.) with breast cancer. Choose unsaturated fatty acids single chain, such as olive oil.
In Sweden have conducted research over six years to more than 61 thousand women aged 40 to 76 years. Those who consume 10 grams of single-chain unsaturated fat each day have a reduced risk of breast cancer up to 45 percent. Conversely, any consumption of 5 grams of unsaturated fat plural chain increases the risk of breast cancer to 69 percent. These data explain why breast cancer is rare in Spain, Greece and Italy, although 42 percent fat calories they get oil form. That's because they consume the single-chain unsaturated fats.
4. Consume lots of vegetables and fruits
Carotenoid pigments found in fruits and vegetables is believed to protect breast cancer. Researchers at New York University comparing 270 blood samples of women with breast cancer with 270 blood samples of healthy women. Women who have had the lowest carotenoid two times higher risk of developing breast cancer compared to the highest berkarotenoid. Try to always include vegetables and fruits in your daily diet, especially carrots, tomatoes, watermelon and spinach.
5. Consume lots of soy
The incidence of breast cancer in Asian women is only one-fifth of Western women. Scientists believe that the cause is a diet rich in soy. An experiment showed that the Japanese fermented soy may reduce breast cancer risk. Those who consume three or more servings per day had a lower risk than those who ate only one serving or less.
Soy contains phytoestrogens that prevent breast cancer by limiting the carcinogenic effects of estrogen. Drinking a glass of soy milk or three pieces know / tempeh every day can protect you from breast cancer.
Breastfeeding is not only beneficial for babies, but also for her mother for suppressing estrogen levels. Researchers compared the birth rate and pattern of breastfeeding women who live in developed countries and developing countries. They found that women in developed countries can reduce breast cancer risk by half if you have more children and breastfeed them as women in developing countries (average 30 months per birth).
7.do not smoking
The younger the woman smokes, the greater the chances of developing breast cancer before menopause. California Environmental Protection Agency reports that passive smoking, especially among young women, is one of the causes of breast cancer. For husbands or fathers, stop smoking so that his wife or daughter you do not have breast cancer.
