My cancer was invasive ductal carcinoma( the most common) and her2 neg.In cancer terms,this is a ' good' thing,because after treatment,you can go on to taking hormonal therapy,such as Tamoxifen,which is what I am on now.Other ladies with different cancers,aren't able to have this added protection,as it is of no use with their type of cancer.Have you got your kit that comes free from BCNA? There is good info in there on all the types and treatments of BC.Hope this helps and keep asking questions,as it really helps if you understand what is happening to you.Cheers xoxRobyn.ps.The kidney function and gated heart pool test are quite standard tests so don't worry too much x
