Breast hyperplasia is a common and frequent disease among adult women. Breast hyperplasia is a kind of non-inflammatory and non-tumor breast disease, which is a structural disorder caused by incomplete restoration of breast tissue after physiological hyperplasia occurs under the stimulation of estrogen. It is a structural disorder caused by incomplete restoration of breast tissue after physiological hyperplasia under estrogen stimulation. The onset of breast hyperplasia is closely related to endocrine disorders, although its etiology is not yet well understood, but one thing is certain, this disease has a close relationship with the ovarian endocrine imbalance. With the changes in ovarian function during the menstrual cycle, the levels of estrogen and progesterone in the body also change cyclically, and the structure of breast tissue also undergoes the cyclical changes of physiological hyperplasia and regrowth. If the estrogen level is too high or the progesterone level is too low or there is a lack of coordination between the two, it can cause structural disorders due to incomplete breast regeneration, i.e. breast hyperplasia. Pain is the most common symptom. The most common manifestation of the disease is breast pain, which is mostly cyclic premenstrual swelling or pinprick pain and can radiate to the armpits, and can be reduced or subsided by itself after the onset of menstruation, and there are some patients whose pain does not change with the menstrual cycle. Most patients feel that they have a lump. In fact, breast hyperplasia is often manifested as thickening of glandular tissue in multiple areas of the breast in the form of lumps, strips or granules, not a lump. However, a small number of people with severe conditions can be found in the breast of the lump is not yet very clear boundaries. There is no specific treatment for this disease, and it should be treated with psychotherapy, supplemented by medication. It is characterized by a chronic process and recurrent episodes. For some patients, if the symptoms are not serious, there is no need for medication, and some of them may recover spontaneously; avoiding fear, tension or depression, maintaining a good mental state, a regular lifestyle and appropriate physical exercise is conducive to the improvement of the condition or the alleviation of the symptoms; dietary adjustments in life are also very important, paying attention to eating a low-fat, fiber-rich, vitamin-rich diet. Severe symptoms can be treated with traditional Chinese medicine; in severe cases, endocrine drugs such as triamcinolone acetonide can also be used, but these drugs interfere with the body’s hormone metabolism to a certain extent, and need to be taken under the guidance of a doctor. Most patients do not need surgical treatment, only in the formation of limited and palpable lumps or can not rule out the possibility of malignancy, the use of surgical methods. Breast hyperplasia, except for ductal epithelial atypical hyperplasia and severe papillomatosis, so far there is no sufficient evidence to prove that there is a definite relationship between breast hyperplasia and breast cancer. It is generally recognized that breast hyperplasia is only one of the many risk factors for breast cancer. Breast hyperplasia does not usually turn into breast cancer, but it is worth noting that breast cancer in its early stages manifests itself in the form of small lumps that are not easy to detect and may be mixed with breast hyperplasia, which is sometimes not easy to identify even by doctors. Therefore, patients are reminded that they must go to the hospital for regular checkups to prevent breast cancer from being under-diagnosed.
