An abnormal increase in the size of breast tissue in males, often resulting in a noticeable enlargement of the breasts.
The doctor explained that gynecomastia can occur during puberty due to hormonal changes.
Gynecomastia is formed from "gyne" (from Greek "gynē", meaning woman) and "mastos" (from Greek "mastos", meaning breast). The term refers to the condition of having breast tissue that is more typical of women, hence the combination of these roots.
Think of 'woman' ('gyne') and 'breast' ('mastos') to remember that gynecomastia refers to the condition of having breast tissue typically associated with women.
