Hi @Whippetlove, I haven’t can’t comment on kadcyla as I haven’t had my surgery yet but I know it is a possibility for me if there is residual cancer left after my chemo. however there is a great feed with lot’s of women that are going through and have been through kadcyla whom maybe able to help you and provide you with some feedback, its for those that are HER2 positive and it’s a very supportive feed, here is the link (if I’ve done it right)!

it’s a long thread but if you go right to the bottom then you can post your question. I hope it helps you and good luck with your kadcyla treatment x
