If men are in a long-term mood, it will not directly cause breast disease, but it may induce the occurrence of hyperplasia of the breast glands. Men who are in a bad mood for a long time, depressed and unstable, will easily lead to hormone level disorders in the body and increased secretion of estrogen levels. This may induce changes in the mammary glands, leading to the appearance of breast enlargement. Male breast hyperplasia is mainly manifested as enlargement of one breast or both breasts, and may be accompanied by pain. It can be treated with anti-estrogenic drugs under the guidance of doctors, such as tamoxifen and clomiphene. It is recommended that patients should always adjust their state, especially for those who are under great pressure from life, work and school, and are in a situation of long-term anxiety. If uncomfortable symptoms occur, it is recommended to consult a doctor in time, under the guidance of the doctor for treatment.
