Indie, you should try to find out if your grandmother has breast cancer before or after menopause. I know that might be a little difficult to find out, but it can make a huge difference. The breast cancer that you have after menopause, for whatever the reason, doesn't carry the same risks for future generations as the one before menopause. My grandmother also had breast cancer, but she had it after menopause, so my mother, sister and I aren't really at risk.

Also, someone mentioned the HPV vaccine. Definitely talk to your doctor about that. Apparently, they're also finding that HPV can cause throat and mouth cancers from oral sex with an infected partner.
