I just found this site today. Found it in search on webmd. I am not sure what a lot of the shorthand you all are using means, but I was wondering about more info! I don't have Breast Cancer. My mom(53 next month) found a lump in rt breast maybe end of Aug 2005. After some coaxing from myself and a friend went to health dept and got a voucher for mamogram (no insurance and didn't qualify for any state help) and biopsy. She had the biopsy on the 27 of Sept. Tests came back positive for cancer. I don't have any of the details as my mom has all the info with her. But the surgeon said it was stage 3 infiltrating ductal carsinoma. He told us the lump removed was too big so lumpectomy couldn't be done. She had a mastectomy on Oct 11 and the surgeon said 1 in 15 nodes came back positive. We met with oncologist and he told is she was her2+ (I see other ladies use multiple +, not sure what that means. I also see a lot of other little notes, UGH I feel dumb!) and estrogen sensitive. Onc said he wanted to do cytoxan with adiramycin for 4 treatments and taxotere for 4 treatments. After #4 add herceptin and after all 8 treatments use anti-estrogen drug for 5 years.

UGH! I just realized the time, mom has an echocardiogram today to make sure heart can take herceptin. Need to go. Can someone help me understand this more? I feel so lost. I read some posts of being on herceptin for 4+ yrs, and I don't know how long my mom will be on it. Is there other stuff we should talk with onc?

Thanks!
