I'm 17 years old, 18 soon, and I found a small lump on my right breast, when I first found it, I was on my period but now 1 week and a half later it's still there. It's hard and not move-able. It's really small, but I'm not 100% sure if its something I should worry about, but I am really worried about it.
I'm some what of a hypochondriac, and I know this, which is why I'm not sure if I'm over reacting like I usually do, or if I really should get checked out.
