Hi @annie7
Welcome to the forum, it’s such a friendly and supportive place. The good news is that the tumour has shrunk and you still have more chemo to go I’m assuming or did you only have 4 cycles?
Some threads might be good to join with your diagnosis/treatment.
HER2 + and need some buddies has been going for over a year with people at different stages of treatment and some finished their active treatment. HER2 treatment can last much longer than chemotherapy. There are a few people on the thread who didn’t get a CPR (complete pathological response) to chemo and have moved on to Kadcyla from Herceptin/Phesgo.
There is also a monthly chemo starters group so you can get support and help from others having similar treatment to you. I have link the November 2024 starters and there are a few ladies on the HER2 thread as well.
