A bud on the breast can be divided into physiological and pathological causes: physiological causes are mainly due to the formation of ulcerative changes in the local breast tissue after breast trauma or acute mastitis, during the healing process of the ulcer fresh granulation tissue is formed and protrudes from the skin surface, resulting in the phenomenon of a bud on the breast. In this case, no special treatment is often needed, and it is sufficient to actively change the medication and keep the area around the granulation tissue clean. Pathological causes are mainly viral infections of the breast skin, causing fibroids, which are common benign skin tumors with a soft texture. All in all, after excluding breast trauma caused by sarcoma on the breast, you should go to the regular hospital dermatology department in a timely manner, and if necessary, perform surgical removal.
