In recent years, the incidence of breast cancer is increasing year by year, and there is a trend of youthfulness. Breast cancer is harmful to women’s health, and it will also affect the harmony of the family to a certain extent. How can women prevent breast cancer from happening? The following are the relevant prevention methods: 1. Regular medical checkups: if breast cancer can be detected at an early stage, the cure rate is up to 80% or more. Therefore, young and middle-aged women should insist on regular checkups. The examination should start from the age of 30. For the general population aged 30-49, once every 1-2 years; for women aged 50 or above, once a year. High-risk groups 30 years of age once a year. 2. High-risk groups should pay attention: such as mothers, sisters or daughters who have had breast cancer. Women aged 40-60 years old, especially those who are obviously fat after menopause or with diabetes. Women who have had their first menstrual period at the age of 12 years and those who have menopause later than 55 years. Women who have had their first birth after 30 years of age, women who have not conceived at the age of 40 or older, single women, women who have married late and women whose marriage has lasted for a short time. Breast cancer on one side and increased risk of breast cancer on the other side. Frequent exposure to radioactive substances. The risk of radiation exposure during adolescence is higher, and radiation-induced breast cancer generally requires a latency period of 10-15 years or longer. Patients with benign breast diseases, such as lobular or ductal hyperplasia. The incidence of breast cancer is not equal for every woman, and the incidence rate of high-risk groups is several times or even more than ten times than the general population. 3, often self-examination: self-examination, not to force push and pull, because malignant tumors are pushed, pulled and kneaded, simply lead to the dispersion of cancer cells. If you have a large breast, you should check it in a reclining position after sitting, and put a pillow on the back of your shoulder to make your breast arch, so that small lumps are not easily lost. The time of self-examination is 9-11 days after the onset of menstruation is appropriate. Women who have stopped menstruating should also be checked on a fixed day each month. Since most breast lumps are discovered by patients themselves, women over 30 years old should check themselves once every 1-2 months. Self-examination method of breast cancer: Find a place to sit down with your arms hanging down naturally or on your knees. Touch your breasts with your fingers in a clockwise direction, without squeezing. If you find any lump in the breast area, you should find a physician for further diagnosis as soon as possible. Through the above introduction, I believe women have their own understanding of breast cancer prevention. Breast cancer is a serious disease for women, so it must be brought to the attention of women to take preventive measures, early detection and early treatment for early recovery.
