Welcome to this network but sorry you are going through this crap journey again.I gather you had a lumpectomy in 2012.I had a similar experience in that I had bc in 2003 (lumpectomy,full node clearance,radiation)and then bc again in the same breast in 2010.My cancer was oestrogen +ve so I've been on Tamoxifen for the last 4 years.I have a girlfriend who had TN twice like you and she had to have chemo again.It will depend on your pathology and your oncologist I would think.Sounds like you have caught it early again which is good news.Such a relief to get clear body/bone scans.I hope you are travelling ok since surgery- a mastectomy can take a little getting used to so blog back if you need to chat. Big hug, Tonya xx
