Some women believe in continually supporting the breast can avoid breast down. But it turned out to be a habit triggers an increase in body temperature around a long time that breast cancer risk.
Two scientists Sydney Singer and Soma Grismaijer his wife in 1991 to do research on how long the ideal time to wear a bra or topless women?
The answer turned out to less than 12 hours. Women who want to avoid breast cancer should wear a bra within the shortest possible time, and preferably less than 12 hours per day.
Singer and learn the habit of wearing a bra Grismaijer 4500 women in five cities across the United States. The result of his studies have been published in a book Dressed To Kill: The Link Between Breast Cancer and bras.
The study showed women who wore bras 24 hours a day during the most high-risk breast cancer. While women who rarely wear a bra at least risk.
Comparison of the results showed:
1. Three of the four women who wore bras 24 hours per day
2. 1 of 7 women who wore bras more than 12 hours per day but did not use while sleeping
3. 1 of 152 women who wear bras less than 12 hours per day
4. 1 of 168 women who rarely or never wear a bra at all
So the risk of women who wear bras over 24 hours has a 125-fold risk of developing breast cancer than those who rarely wear a bra.
The best time to rest my breast without a bra is during sleep. "Do not sleep with a bra," said Sydney Singer, as reported from chetday, on Friday (04/23/2010).
Breast massage with a deep breath each time removing the bra can expedite the flow of lymph nodes and prevent the development of breast cancer.
The lymphatic system is fully developed only in the breast during pregnancy and breastfeeding, so women who wear bras everyday and postpone having children who are not breastfeeding can be exposed to higher risk of breast cancer.
Approximately 75 percent of women affected by breast cancer actually have no risk factors for cancer. This raises a presumption that the use of fitting bra or a bra constantly is a factor that can explain this.
Bra size that is not appropriate or too tight can assist in the growth of breast cancer. Because the wrong bra can inhibit the neutralization of hazardous chemicals in the body that cause cancer. And about 80 percent of women use the wrong bra.
The main reason why a tight bra can be harmful to health is because it can restrict the flow of lymph in the breast. Normally, lymphatic fluid wash of other toxic materials and waste, and keep him away from the breast.
Using the bra is too long also increase the temperature of breast tissue, and women who wear bras have the hormone levels of prolactin (hormone that functions to stimulate the milk glands) is higher. Both of these can affect the formation of breast cancer.
