I found a little lump in my left breast and I'm a guy! It only hurts a little
when I press on it. What could this be? – Tyrone*
When a guy goes through puberty, all kinds of changes take place in his body. One
of these changes can be a condition called gynecomastia, when breast tissue enlarges.
That small lump with tenderness beneath the nipple is a normal part of puberty. In
fact, about half of all boys develop gynecomastia during puberty. It's usually temporary
and can happen on just one side or both. Some guys also may feel tenderness in the
breast area when they go through puberty.
Breast changes in teenage guys are part of puberty — and they're rarely serious.
Some signs that it might be serious are if the lump gets a lot bigger, becomes
hard, or if you notice any fluid coming from your nipple. If that happens, see your
doctor just to make sure it isn't a sign of another problem — though, again,
breast changes in teen guys are almost never serious.
Even if you're not worried, it's always a good idea to talk to your doctor about
your changing body. Your doctor is your best resource when it comes to your health.
Plus, getting used to talking to your doctor now will help you get more out of your
medical care as you grow up.
