I was diagnosed with triple negative breast cancer at the end of June 2021. I was 49 at the time.  I had one cycle of EC but just before the second dose the tumour had increased.   I was changed to carboplatin and paclitaxel.   I only had one cycle of that - I had a reaction to carboplatin. I was called in by the surgeon who told me that a lumpectomy was no longer viable and chemo would be paused to allow for surgery.  He commented that he thought 40% of the breast was compromised.  I had a mastectomy at the beginning of September.  

Lymph nodes were clear.  CT and bone scan showed unrelated problems but no sign of metastasis.   However the biopsy showed the tumour hadn't responded to the chemo.

I have completed 15 sessions of radiotherapy.   I am now two cycles into Capecitabine.  

Given how fast things progressed, I'm worried about recurrence.   How do others deal with this worry.

I keep checking my remaining breast.  I keep thinking I can feel lumps, albeit small marble sized.  I don't want to look like a hypochondriac.   Do I mention these at my next appointment in a weeks time? 

Thank you
