Treatment decisions-Triple negative

Hello ladies. I thought I would just quickly post about my experience with Capecitabine/Zeloda. Oct 2019 I was diagnosed with small triple negative tumour in right breast, hadn't spread to nodes. I had chemo followed by lumpectomy followed by radiation instead of the mastectomy I wanted thanks to COVID in 2020, as Drs wanted to keep me out of hospital. In October 2020 my oncologist asked if I would be interested in taking 8 cycles of Capecitabine as there was a recent study indicating very good results with reducing the recurrence of triple negative breast cancer over a 5 year period.  The study, though, only included triple negative stage 3 that had spread to lymph nodes or beyond. So it wasn't definitive that the Capecitabine would do anything. My tumour was *mostly* dead after first lot of chemo but considered resistant. I'm just finishing up the Capecitabine tablets now, June and haven't had any terrible side effects or long term effects as far as can be seen. I have some liver damage from the first lot of chemo. I decided after some back and forth to take the Capecitabine as it might do some good with any cancerous cells that had not been dealt with by chemo and radiation and so long as it didn't seem to be doing any harm or causing harsh side effects. I didn't experience any nausea, there has been some fatigue, particularly getting to the end of the 8 cycles. If anyone with triple negative breast cancer who went on to mastectomy would like to comment or direct me to your post, that would be appreciated as that's the next thing I'm trying to decide. My surgeon considers its "probably" not necessary, more a peace of mind situation.
