@Mjheke You are in a similar position to me. I was 51 when diagnosed in December last year.
If my BC had been the first in my family I would have proceeded to radiotherapy after my wide local excision and re-excision. However as my sister had died from it and my mother had had it at my age, my oncologist thought that if I could afford the genomic test I should do it. It cost $3000... I did it and it came back a clearly positive that chemo would have a cuative effect if some cancer cells were looking for somewhere else to roost in my body. So I took a very deep breath, accompanied by a lot of swear words and a massive panic attack two nights before I started, and had chemotherapy.
No regrets. I've done everything I can to beat it. If it comes back, it comes back. I can have done no more.
Chemo is not fun by any stretch of the imagination but you manage.
All the absolute best for your decision. PM me if you want to chew it over with me in person darl. K xox
