One other thing: look for symmetry. As I said, I had lumpy breasts forever and I learned to look for lumps in the same place in the other breast. If you find symmetrical lumps, then it is probably nothing to worry about. So if you find a lump (and it does NOT have to be hard and pea sized to be cancerous) on the outside of your right breast, see if you can find one on the outside of your left breast. Also, regular self exams will help you recognize a new lump that might need checking out.
