I had a very small her2 cancer and it's known to be aggressive. Although I was told my surgery was potentially curative the recommended treatment was an aggressive chemo and herceptin. Mine was grade 3 and I had a clear mammogram only 6 weeks before. I didn't want to live with regrets if not doing all for cure. So I did follow the recommended. It was hard but I have no regrets. I also had a bmx but with reconstruction. I wanted to reduce my chances of local recurrence or a new primary growing and being undetected. I continue on also on anastrazole as my cancer was estrogen positive as well and am almost at 5 years with another 5 to go.
I knew from the beginning I would need chemo. It didn't stop me being weepy when I had that consult and sitting waiting for my heart scan in prep for herceptin. It's all part of the acceptance and acknowledgement of facing a life threatening illness.
