Try not to worry although I know it's almost impossible.I think it's always best to be guided by your doctor,if you feel confident in them.We all have different results,but only your own doctor knows YOUR results precisely.This journey is so up and down,that's why it's often referred to as a roller coaster.Remember though,that these days,no matter what treatment you need,BC is usually very treatable .I had a mastectomy,then chemo,now Tamoxifen,and I feel pretty good:)All the best with whatever you need,and stay on here for support and advice from others that have already been there and are doing great :) xoxRobyn
