My mum has been diagnosed with HER+ hormone negative grade 2 (with axilla lymph node spread but further CT clear so I think considered curable) breast cancer. Due a mastectomy & lymph node clearance soon. She is in good health, no major comorbidities apart from high blood pressure & painful OA which has really reduced her mobility this year. I think she is likely to be offered chemo after the mastectomy. Can anyone offer any advice on whether chemo is much harder in someone her age? How does she balance the risk of the treatment being worse than the chance of the cancer progressing/returning? She will have a meeting with the oncologist after the results from the mastectomy are back - is there anything she needs to think about asking? Thanks.
