Dear Clare,
Thank you for writing. I am sorry your mum did not have a better result.
Unfortunately, there is some TNBC that seems to be chemo-resistant at times.
I am a patient advocate working on a volunteer basis for SAGE Patient Advocates(SAGE), a non-profit foundation, and I have helped several hundred women on this site over the last 11+ years. I am not a medical professional and I will not give you/your mum medical advice but I am hoping I can be a useful resource for you. There are Breast Medical Oncologists, in the UK, who are experts in TNBC and hopefully I can help secure a consult, IF you are interested.
There are no charges to you/your mum, from myself or SAGE.
Please send me a PM and I will be happy to invite you to a Zoom conference or have an email conversation. Will also send you my phone number.
sometimes I don't receive PM so you can also send me an email at
contact@sagepatientadvocates.info
warmly,
Steve
