I am 77 yo. I'm being treated for IDC in Germany. There are differences. After breast conserving surgery and lymphedectomy of 18 nodes, showing a 1.2 cm breast tumor and one positive node, I was advised not to take chemo but to go directly to radiation therapy. My surgeon said only one person in ten in my case is helped by chemo. I am so optimistic I thought he meant 90% of people in my case would not need chemo. I did not undergo chemo. I have just completed 6 weeks radiation. However - now that I have time to research I see my tumor markers are so high - Ki-67 is 40, for instance, that he must have meant only 10% could be saved by chemo in my case. Are tumor markers that indicative? Should I go back and take chemo now - or just wait?
