Breast Lump
Little lump in breast and hurts a little when press on it.
When a guy goes through puberty, all kinds of changes take place in his body.  
  • One of these changes is often a condition called gynecomastia, when breast tissue enlarges.
  • This is usually temporary, and can happen on just one side, or both.
  • Some guys may also 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.
 The small lump with tenderness beneath the nipple is a normal part of puberty, and lots of guys experience it.
