Most of the breast hyperplasia in elderly men is not particularly serious, and only a very small number of patients may develop breast cancer, which is more serious in this case. Generally speaking, the cause of breast enlargement in elderly men may be related to the imbalance of the ratio of estrogen and androgen in the body, which in turn causes the abnormal proliferation and development of breast tissues, in which case most of them are not particularly serious. Some patients can get better on their own even without treatment, and if there is an underlying cause, the elimination of the cause can also lead to the disappearance of symptoms, so male geriatric breast enlargement is not serious. It should be noted that many diseases can cause estrogen secretion disorders, such as oncological diseases, which have persistent and more severe symptoms, and a very small number of men are likely to develop breast cancer, in which case it is more serious. In conclusion, the elderly should cooperate with the doctor for examination and treatment as soon as possible after the symptoms of breast enlargement are detected, so as not to delay the condition and avoid further development of the disease, which will affect the prognosis.
