Q83.8: Other congenital malformations of breast

The condition known as "Other congenital malformations of the breast" refers to an array of unusual and rare breast anomalies present from birth. These anomalies can take various forms such as asymmetry (one breast is larger than the other), amastia (absence of one or both breasts), polymastia (presence of more than two breasts), or athelia (lack of nipples). The root cause of these conditions often lies in the developmental phase during gestation when breast tissue forms incorrectly. The presentation of these conditions may vary greatly from patient to patient but commonly they are identified by visually noticeable differences in the structure of the breast or nipple, or by differences in touch compared to the normal breast tissue. These conditions may not pose any immediate health risk but can cause anxiety or self-consciousness, and in some cases, can be associated with other health issues.
