Hi @lisalisa welcome to the forum. As @sharlou has said it’s just the timescales used on the Predict score. I know of a lady who had a mastectomy 34 years ago and she’s still here. Had it been now she may have had a lumpectomy and radiotherapy, Treatments have changed over the years and the Predict score has recently been updated to included bisphosphonates.
As you are HER2+ you may like to join the thread HER2+ and need some buddies, it’s been going for over a year with some of us finished active treatment, some on Phesgo/Herceptin/Kadcyla other like you having chemo.
Here’s the link if your interested
Are you on one of the monthly chemo starters group? It’s another supportive way to get through treatment with others in a similar position as you. This is the November thread as I you said you’ve had 4 cycles so far.
Take care
