The probability of young women in their thirties coming to the clinic with breast discomfort has been reported to be very high recently. Cancer continues to be a difficult disease with a very high mortality rate, and such early detection is not a sensitivity, but a proper control measure. Why do you develop breast cancer? The known causes of breast cancer include early menarche, late menopause, short breastfeeding, unmarried children, family history of breast cancer, oral contraceptives, obesity and high fat and low fiber diet, smoking, and staying up late. In recent years, with the improvement of China’s economic development level, women’s lifestyle has produced significant changes, mainly the westernization of diet, which is high in sugar and fat; in addition, the fast-paced life makes staying up late, late marriage and even infertility a mainstream phenomenon, which affects the normal operation of endocrine and becomes the main cause of breast cancer in modern women, especially young urban women. For young women, there is no need to be overly nervous in the face of breast cancer. However, young women should not ignore it and take normal preventive measures. First, they should change their lifestyle habits, including a healthy diet and a good mindset. Women should see a breast surgeon every six months, women between the ages of 20 and 39 should have an annual mammogram, and women over 40 should also have regular mammograms. Self-examination of the breast is not a good way to detect early breast cancer and it does not replace other screening methods. Regular mammograms are a must, regardless of whether you have painful breasts or whether you can feel a lump. Tip: Some “high-risk groups”, such as women with a family history or other breast diseases, should have regular mammograms after the age of 35, as recommended by their doctors.
