Normal breast structure

The breast is made up mainly of lobules (glands that can produce milk if the right hormones are present), ducts (tiny tubes that carry the milk from the lobules to the nipple), and stroma (fatty tissue and connective tissue surrounding the ducts and lobules, blood vessels, and lymphatic vessels).

Until puberty (on average around age 9 or 10), young boys and girls have a small amount of breast tissue consisting of a few ducts located under the nipple and areola (area around the nipple). At puberty, a girl’s ovaries make female hormones, causing breast ducts to grow, lobules to form at the ends of ducts, and the amount of stroma to increase. Even after puberty, men and boys normally have low levels of female hormones, and breast tissue doesn’t grow much. Men’s breast tissue has ducts, but only a few if any lobules.

Like all cells of the body, a man’s breast duct cells can undergo cancerous changes. But breast cancer is less common in men because their breast duct cells are less developed than those of women and because they normally have lower levels of female hormones that affect the growth of breast cells.
