I am not a doctor but I can tell you with extraordinary confidence that if you are HER positive, standard treatment is one year of herceptin and 12 rounds of taxol. It is the standard of care backed up by years of clinical trials. If you didn't have this, I would investigate. Recurrence for these tumors is high but with herceptin and taxol, the risk is much much lower. I had an 8mm tumor and did this regimen, which is clearly outlined in medical journals.
