Can wearing a bra for a long time lead to breast cancer? Five common causes of breast cancer

Bras, or underwear, are essential close-fitting clothing for women, but this intimate clothing that is touched every day may cause breast cancer. Let's take a look at the harm of bras to female friends. Breast cancer is a malignant tumor that is extremely harmful to women. There are many causes of breast cancer, and many living habits and reasons can lead to breast cancer. Experts at the Biotherapy Center said that wearing a bra for a long time may also lead to breast cancer. The causes of breast cancer are related to race, genetics, marriage and childbirth, menstruation, breastfeeding, eating habits and other factors. But a recent survey found that the incidence of breast cancer is also related to improper wearing of bras. In the United States, women have long had a tradition of wearing bras, and the incidence of breast cancer is very high, while in Japan, there is no such habit, and the incidence is much lower than that in the United States, so they think wearing a bra is an important factor. The harm of long-term breast cancer: 1. If the wearing time exceeds 12 hours, the induction rate of breast cancer can reach 75%. The induction rate of breast cancer can reach 75% for more than 12 hours a day. Therefore, if you can try not to wear a bra at home or in non-public places, it will help prevent breast cancer. Recently, the Shanghai Women's Disease Rehabilitation Committee released the latest survey, which showed that 79.3% of women in the city are not suitable for wearing bras. The main manifestations are: long-term wearing, tight chest, and no adjustment. Clinical statistics also found that wearing a bra for more than 10 hours a day is prone to breast diseases, and the probability is twice that of other people. In addition, improper bra wearing may also cause the following health problems. 2. The bra straps are too tight and compress the breasts. In addition to causing shoulder discomfort, tight straps will also cause the bra to move up. The bottom of the current bra is fixed with steel support. Therefore, if the bra moves up, the harder steel support will compress the breast tissue. If a girl moves up during exercise, she must adjust the underwear in time. 3. Improper bra wearing affects lymphatic return. Many women displace their breasts when wearing them, that is, from the outside to the inside. Therefore, the appearance of the breasts is very beautiful, but it affects lymphatic return, slows down metabolism, increases toxins in breast foam, and increases the incidence of disease. 4. Improper wearing of bras can lead to insufficient blood supply to the breasts. Inappropriate bras can cause breast pain: If the bra is worn too tightly for a long time, the pressure area under the breast will have poor blood supply and fibrosis, forming thickened cords and painful pressing. 5. The specific impact of inappropriate bras on the breasts is first of all milk duct blockage. Because the bra is close to the nipple, the nipple rubs against the bra fiber, causing the fiber to rub into a cocoon and enter the milk duct. Over time, milk duct blockage will not only affect future breastfeeding, but also cause mastitis. Second, it is easy to cause nipple inversion. If the length of the bra is shorter than the bust, the bra will tightly compress the breast, affect the blood circulation of the breast, compress the nipple, make the nipple flat or even concave, which will also affect future breastfeeding. 9: Women are better off not wearing bras. If necessary, no more than 12 hours a day. Remove at home, leisure and sleep. The bra should be large but not tight. The material should be pure natural fabric, and chemical fiber and other substances should not be used.
