Triple Negative Breast Cancer Reoccurrence

Hi all,

I'm hoping to find people who have been in a similar situation to me.

I was diagnosed with Triple Negative Breast Cancer in April 2023. I had 12 weekly sessions of carboplatin, paclitaxol and immunotherapy, the had 4 cycles of EC and immunotherapy every 3 weeks.

My lumpectomy was in October 2023 and in December 2023 I was given and all clear with a complete pathalogical response. I still had radiotherapy and more immunotherapy to prevent a reoccurrence with treatment finishing in July 2024.

In March 2025 I had a mammogram and they found a lump in the scan that turned out to be a tnbc reoccurrence. My CT scan showed no spread and I had a mastectomy in April 2025. They were able to completely remove the tumor and it hadn't spread to my lymph nodes.

Had my oncology appointment today and they have said my situation is rare and there is no treatment protocol for it. My oncologist had chosen a chemo for my that comes with some side effects and a higher risk of a second cancer due to my previous treatment.

I now have to decide whether to have the chemo or no further treatment. If I don't have chemo I have a 72% chance of being here in 10 years compared to 80% if I do have the chemo.

I have no idea what to do for the best. Has anyone else been in this position and what did you do.

Thanks in advance all xx
