Hi em_24, I also had Grade 1 (certainly not as young as you ;)) but with no nodes involved and have had mastectomy with no radiotherapy or chemotherapy. I felt at first that I was being neglected by only having tamoxifen HOWEVER my radiotherapy oncologist put my mind at ease by telling me that should I go ahead with say chemotherapy given my cancer was a grade 1 that I would more than likely be doing my body more damage and it wasn't necessary. That has helped me come to terms with the idea of no further active treatment and I now concentrate on how lucky I was to have a grade 1 cancer. All the best and I hope you can get to the point of less worrying. Xx Cath
