I had your diagnosis but 19mm and no nodes. I was so relieved all numerous scans were negative. I had ACT-H chemo which is slightly more toxic to the heart but I read they have done clinical trials and found TCH was very effective with less heart issues. My T (taxol) was weekly for 12 weeks. 2 years on and cancer free. My niece. ..same diagnosis 14 years on cancer free with positive nodes initially.
It's not an easy road and sleep is awful but eventually you will hopefully start to sleep a bit and feel comfortable and settled into your treatment as much as anyone can. Kath x
