There are benign and malignant lesions in the breast, and malignant lesions are relatively more serious, i.e., common malignant tumors of the breast. These include breast cancer and breast sarcoma, which are more common in middle-aged and elderly patients due to changes in hormone levels. Patients who are diagnosed at an early stage should be treated promptly with radical resection surgery. Because malignant tumors of the breast are prone to metastasis of distant organs or recurrence after surgery. Therefore, after surgery, intravenous chemotherapy or radiation therapy is also needed to prevent recurrence. Regular review and follow-up should also be paid attention to. For benign tumors that are not serious, if the lesions gradually increase in size and affect the aesthetics, surgical treatment can also be chosen. For those caused by simple hyperplasia, oral medications against breast hyperplasia can also be taken.
