Hi @ali67
Welcome to the forum but also sorry to hear of your diagnosis.
I am also HER2 positive and have had 12/18 injections. I read someone else on the forum was offered only 9. If I remember they had a low grade small tumour. I am bi lateral (one tumour in each boob) grade 2 2cm and grade 1 9mm.
I spoke to the Sciencus nurse who has taken over my injections now I have finished chemo and receive them at home. I asked them about the 9 injections rather than 18 and they mention the Persephone trial, which they believed has now finished.

Some other HER2 buddies here if you want to join this thread.
There is also a monthly chemo starters group, to have a supportive group going through chemo with you. Here are the links for May and June 2024. I found it helpful to read previous months to get an insight of what to expect.
You could as already suggested call the BCN nurses or ask again to speak to one of your oncology team to discuss the pros and cons of your treatment plan, including your Predict data.

Hope this helps
