Pediatric and adolescent breast pathology

In pediatric patients, breast masses are relatively rare and – if they do occur – most are benign. The most common breast abnormality seen in children younger than 12 is a unilateral breast growth where one breast grows faster than the other. In these cases, while one breast develops earlier than the other, most often they ultimately become symmetrical.

What is pediatric and adolescent breast pathology?

Breast pathology is an abnormal area of development or an abnormal growth in the breast. In rare cases, breast abnormalities can occur from birth. Athelia (absence of nipples) and amastia (absence of breast tissue) may occur on one side or in both breasts. 

An extra breast (polymastia) or extra nipple (polythelia) occurs in about 1 percent of the population, and are slightly more common in males than in females. This extra tissue may cause discomfort during menstrual cycles and may need to be removed.
