I had micromets on one node in January 2012, I went on to have a full clearance, the rest were clear, but I also know of people with micromets who had a full clearance and other nodes turned out to be affected too. I was 43 when diagnosed with a 19mm, grade 2 IDC. Strongly ER+ and I was advised to have chemo for 2 reasons, 1 because I was considered young for breast cancer, and 2 because of the micromets meant that the cancer was on the move and there was a risk, albeit a small one of spread. I didn't hesitate and grabbed chemo with both hands. Chemo was doable and I was reasonably well, I continued to work through most of it. I also had 20 fractions of rads and now on Tamoxifen, 16 months after finishing chemo I'm really well, have a great head of hair and delighted that I've done everything I can to ensure that I'm around to see my little girl grow up.
