The condition of painful breast compression without pressure is usually seen in patients with mastocytosis. Mastocytosis, a benign condition in which periodic breast pain is caused by abnormal changes in estrogen levels in the body, is a proliferative mass. Mastocytosis is neither an inflammatory condition nor a tumor. Its occurrence is related to unhealthy eating habits, poor lifestyle and bad emotions, and excessive intake of drugs or foods containing exogenous estrogen. Once this happens, you should go to the general surgery department of a regular hospital in time to receive a specialist physical examination and mammography to further understand the condition and exclude any breast lumps that may be present at the same time.
