A. High incidence Simple breast hyperplasia is a common and frequent disease of the breast in women of childbearing age, and most of them belong to the scope of physiological changes. The proportion of women with symptoms of simple breast hyperplasia is more than 50%, and most of the patients in breast surgery clinics come to the clinic because of simple breast hyperplasia. The incidence of “cystic hyperplasia”, which is a pathological change, is only 5% in adult women. The incidence of this disease is high and very common, but the number of those who really belong to pathological changes is relatively small, and the percentage of those who develop cancer is even smaller. Therefore, patients need not be highly nervous. Most of the patients come to the clinic because of the painful swelling of both breasts, mostly because the pain increases during premenstrual period. In severe cases, both breasts cannot be touched, and some of them affect life, work or rest, and are emotionally tense. Some also present with unilateral breast pain. Pain is not necessarily obvious, and hyperplasia is not necessarily painful, and hyperplasia and pain are not strictly proportional. The relationship between hyperplasia and pain is not strictly proportional. It is also related to the degree of sensitivity, attention and tension of the individual. Some patients find lumps in both breasts or one breast on their own, which may or may not be related to menstruation. Third, the treatment of mammary gland hyperplasia The aim of treatment of simple hyperplasia of the breast is to control the symptoms mainly. Keeping a cheerful and happy mood, reducing stress and eliminating the fear of cancer all have a positive effect on relieving pain; you can also take medication (mainly proprietary Chinese medicine). Only a small number of patients belong to cystic hyperplasia of the breast, and these patients need further examination and are recommended to be seen in breast specialists. The relationship between breast hyperplasia and breast cancer The chance of cancer in simple breast hyperplasia is about 1 per 1,000; however, the risk of breast cancer in women with cystic hyperplasia is 2-4 times higher than that of ordinary women. Since mammary gland hyperplasia is a multiple and common disease, and those who develop cancer in mammary gland hyperplasia are, after all, a very small number of people. Therefore, most of the patients with breast enlargement are still far away from breast cancer, so there is no need to be overly worried and highly nervous, not to mention the “fear of cancer”. The purpose of regular review and follow up of breast enlargement is because breast enlargement is a common and frequent disease, which can be diagnosed by doctors in small villages and even in tertiary hospitals; most patients are not unfamiliar with this disease. Even so, you should not just follow the “hyperplasia” treatment forever. During the treatment process, you should also review your breast ultrasound (and sometimes mammogram) regularly in order to detect and treat diseases that may be combined with breast hyperplasia (breast cyst, adenoma, breast cancer, etc.) early.
