Welcome Twiggyjumps, I wanted a mastectomy but surgeon said it wasn't necessary so had lumpectomy. Pathology came back worse than expected so had mastectomy with lymph node removal last August. I wouldn't have been happy anyway as my breast was about half the size of the other one after lumpectomy. I am having the other breast removed & reconstruction of both later this year. Have just finished chemo & soon to start radiotherapy. My surgeon said removing the other breast doesn't improve survival rates but my tumour wasn't picked up on mammogram as it was hiding behind dense breast tissue & I don't want that to happen again on other side. It is a hard decision, good luck!
