Never really talked to other people with breast cancer before. I had surgery a lumpectomy 2 weeks after diagnosis. And radiotherapy for 4 weeks. Im doing ok. Im a nurse on a breast cancer ward. My surgery was on my own ward. Returning to work in january and feeling anxious. Have felt lots of bone pain on letrozole just changed to aridimex. Anybody else had problems with side effects? Will never stop taking them, for 5 years but loss of libido another side effect too!!
