Many women are diagnosed with mammary hyperplasia during medical checkups, what is mammary hyperplasia all about? Mammary gland hyperplasia is a non-tumor, non-inflammatory proliferative lesion that occurs in women of any age after puberty, and is divided into lobular hyperplasia and ductal hyperplasia depending on the location of the hyperplasia. Mammary gland hyperplasia is a disease in which the number of epithelial cells in the lobules and ducts of the breast increases due to endocrine hormone imbalance or mental factors. It is associated with a decrease in the secretion of progesterone and a relative increase in estrogen. The main manifestation is breast swelling or tingling pain, which appears or worsens several days before menstruation and decreases significantly or disappears after menstruation; the pain may also fluctuate with emotional changes. The pain may fluctuate according to the mood, and there may be lumpy or nodular breast lumps, often with tenderness. In some cases, nipple overflow and other symptoms may occur. Mammary gland hyperplasia and precancerous lesions: clinically, 95% of mammary gland hyperplasia is simple hyperplasia, which is not cancerous. As women age and become postmenopausal, the estrogen level in their bodies becomes lower and lower, the breast tissue degenerates and the hyperplasia slowly improves. Among mammary hyperplasia, only ductal epithelial atypical hyperplasia may become cancerous. Through some imaging and pathological examinations, as well as hand examinations by professional doctors, it is possible to identify ordinary lobular hyperplasia and this precancerous lesion, and not all precancerous lesions will eventually develop into breast cancer. Therefore, we cannot equate mammary gland hyperplasia with precancerous lesions. Treatment and prevention of mammary hyperplasia Treatment and review: (1) General hyperplasia usually does not require any treatment. Most patients will resolve on their own after a few months to 1 to 2 years of onset. If they do not heal on their own for a long time, further examination is needed. (2) Atypical breast hyperplasia is also benign and differs from general breast hyperplasia in that it not only has an increased number of epithelial cells, but also has oddly shaped cells. Having atypical breast hyperplasia increases the risk of breast cancer to some extent. If you are diagnosed with atypical breast enlargement, your doctor will advise you whether to undergo tissue removal surgery or recommend regular review to observe the changes in the enlargement, depending on your actual condition. Even if you have undergone excisional surgery, a review every 1 to 2 years is recommended. Prevention: (1) to maintain a relaxed mood, avoid mood swings, and not to have long periods of mental depression, especially in the premenstrual period; (2) to combine work and rest, avoid overwork, and participate in appropriate sports activities to enhance their immune function; (3) to pay attention to the structure of the diet, avoid eating or less spicy and stimulating food, especially during the treatment period should follow medical advice; (4) a harmonious sexual life, to maintain the body’s (5) not to use hormone-containing cosmetic products for a long time; reduce the use of hormone-containing tonic products. Women need to raise their awareness of self-care, maintain a healthy lifestyle and diet, and adhere to regular breast self-examinations and physical examinations, because atypical breast hyperplasia has a certain cancer rate. Once a breast lump is found or when there is breast swelling and pain during the menstrual cycle or nipple overflow, you should go to a specialist hospital for examination and confirmation in order to prevent hidden dangers.
