At the 5th Shanghai Breast Cancer Forum in November 2010, experts reported a set of data obtained from our scholars about the incidence of breast cancer in Chinese women. The study included 3,000 female cases and analyzed the risk factors for breast cancer in Chinese women. The results showed that menstrual history, early menarche, absence of childbirth, older age at first birth, and not breastfeeding were the high risk factors for breast cancer. Induced abortion was not a high-risk factor. Analysis of hormone levels showed that levels of endogenous testosterone and estrone were significantly higher in breast cancer patients, while exogenous estrogens such as oral contraceptives were not a high risk factor. Obesity is also strongly associated with breast cancer. However, weight at birth is not associated with the risk of developing breast cancer. Physical activity significantly reduces the risk of breast cancer. In terms of diet, the findings advocate the intake of yellow and dark green vegetables, cruciferous vegetables (cauliflower, cabbage, radish, etc.), legumes, soybean oil, and folic acid, which have protective effects. Red meat (pork, beef, and lamb) and fried foods increase the risk of disease. In addition, in a survival study that included 5,000 breast cancer patients, it was found that increased intake of soy products reduced the risk of death and the risk of recurrence. The study is continuing, and expect it to yield more significant findings. Women can help reduce the incidence of breast cancer by practicing a healthy and good lifestyle. Living a healthy life also helps to improve survival and reduce the recurrence rate of breast cancer patients.
