My 14 year old son came to me a couple of days ago and told me he has a hard lump under his left nipple. He wanted me to feel it. So after convincing myself that I'm not a pervert for feeling up my son's nips, I felt the lump. He's right, it is a hard little lump right under his nipple. Of course my first thought was fear, because I know men can get breast cancer, but before I called Kaiser I decided to do a google search.
It turns out that pre-pubescent boys can get little lumps there because the hormones in their bodies are going a little crazy, including the estrogen they have. Basically from what I read, my son is growing a boob. Not to worry, it's not permanent and will (hopefully) go away.
I told my son what I found and assured him it would go away, and then I said, "The good news is, you should start your period soon." He laughed and said, "Heeeyyyy!"
I had to go to Target later, so I told my son I would pick up a bra for him while I was there. That little brat came back with, "Don't bother, I'll just use one of yours. It's not like you need it."
Score one for the kid.
And before I get any unnecessary advice, he has an appointment with the doctor, just to make sure it's nothing.
