Benign breast fibroids usually do not recur after excision, but they can still occur in other parts of the breast. Fibroids in the breast are associated with estrogen stimulation in the body and are usually solitary, but can also occur in multiple or bilateral breasts. The surface of the tumor is smooth, tough, with clear borders, no adhesion to skin and surrounding tissues, easy to be pushed in the breast, with a sliding sensation when touched. The possibility of fibroid tumor becoming cancerous is very small, but there is still the possibility of sarcoma becoming sarcoma, so the treatment is based on the principle of surgical excision.
