Mammary tumors are not serious diseases and rarely appear as malignant lesions. Mammary adenomas are mostly benign tumors of the breast that occur in young women and are associated with an imbalance of sex hormone levels in the patient’s body. There are several types of mammary tumors. The peak age of onset of fibroadenoma is 15-25 years old, mammary malformation tumor can occur after childbirth or in menopausal women, and another condition is lipoma. All three are relatively common breast tumors that can be treated surgically and are less likely to recur. In the case of intraductal papilloma, which originates from epithelial cells in the ducts of the breast and has malignant potential, it is relatively more serious and should be surgically removed after a clear diagnosis. Mammary tumors are better treated and patients need to be actively treated according to medical advice. After surgery, patients need to be reviewed regularly to prevent malignant lesions.
