I’m hoping to get some advice on the next stage of my treatment.
I was diagnosed with HER+ breast cancer last May. I had 7 rounds of chemo, which totally got rid of the tumour. I then had a lumpectomy and 4 lymph nodes removed. 2 lymph nodes had residual disease so I then had a full clearance.

Tomorrow I begin my 15 sessions of radiotherapy. After this I have been advised I will be switching from herceptin to Kadcyla.

Part of me feels really apprehensive as the herceptin doesn’t give me any side effects at all and I’m planning a phased return to work. I’m finally starting  to feel like a normal person again. I’ve read about Kadcyla and I know it is going to be much harsher. I feel like I’m being stupid for turning down what I’ve been told is a better drug, but then I feel like Kadcyla will be a massive backwards step.

Please can you share your experiences of Kadcyla to help me make a more informed decision. There really isn’t great deal of information about it.

Thank you xx
