I am a 38 year old female and in August I was diagnosed with infiltrating ductal carsonoma. To make a long story short, I have had a lumpectomy and one round of chemo. I went to a followup appointment with my oncologist today following my 1st treatment. She told me that my PET Scan, CAT Scan, and cardiogram were all clear. With my lumpectomy my margins and nodes were all clear. I did test HER2 positive. I am really just confused as to why I am having to have Chemo if everything is clear. Can someone convince me that I am doing the right thing by having Chemo. Thanks!
