Lobular hyperplasia is not a disease, but a physiological change in the breast. The pre-menopausal breast is regulated by estrogen and progesterone secreted by the ovaries, so there is periodic breast swelling and pain and some discomfort. Estrogen will make the glands and ducts of the breast proliferate, while progesterone will promote their rejuvenation. Therefore, the breast is regulated by estrogen and progesterone every month, and the process of proliferation and rejuvenation will occur. However, endocrine secretion is also affected by other factors in the body, such as fatigue, psychological state, work exertion, etc., which may cause the last cycle of rejuvenation to pass before the next cycle of hyperplasia has come. It may also be accompanied by other stimulating factors that cause irregular and irregular proliferation of breast cells. Lobular hyperplasia is quite common among contemporary young women and can easily cause panic in some women. However, in fact, if lobular hyperplasia is diagnosed, it does not require any treatment because it is just a physiological process. The chances of lobular hyperplasia becoming cancerous are very low. Women who have lobular hyperplasia should have a mammogram once a year if they are 35 years old or older to detect the disease, treat it early and improve the effectiveness of treatment. ”Dinky women are more likely to be at risk for breast cancer than the lobular growths mentioned above. The incidence of breast cancer is significantly higher in women who are celibate, or over 40 years old who are unmarried, infertile or have their first child over 30 years old than in women who are normally married. Women over the age of 40 should have a mammogram every one to two years. Mammograms can accurately detect breast cancer before there is any trace of the disease. With this early screening tool, many patients are able to detect small, untouchable breast cancers in the first place, saving precious time for treatment. For women under the age of 40, due to the dense breast tissue, X-rays do not penetrate enough, and about 30% to 40% of young women with breast cancer have difficulty in detecting the lesions with the help of X-rays. Therefore, Professor Shao hopes that this high-risk group will use breast ultrasound as the first choice for early breast cancer screening.
