Sorry to hear of your diagnosis . I know what you mean about triple negative being confusing, as most BCs are hormonal and have a different treatment plan.
I was diagnosed with triple negative last year and also have the BRCA gene. I'm only 39 and we have no family history of cancer, so it was a big shock. No one else in the family has tested positive for the gene, so there's actually a chance I could be the first. It's rare but possible.
If you find out you have the BRCA gene, your medical team will advise a bilateral mastectomy and ovary removal. Ofcourse the choice is yours but I choose to have a bilateral mastectomy with immediate reconstruction straight after I finished chemo. I'm also booking ovary removal.
Now I've had my mastectomy, I feel a sense of freedom knowing I've done everything possible to eliminate a reoccurrence. Chemo was the pits , don't want that again!
It will be much easier for you to make decisions once your gene results come back. By the sounds of it, your surgeon is confident the lumpectomy was successful and you will just need to be monitored closely for the next few years.
My oncologist said that with triple negative, even though it is one of the hardest to treat, once you pass the 2 year mark all clear, chances of a reoccurrence hugely decrease (in comparison to hormonal BCs).
Good luck with the gene result . Fingers crossed for negative. They should fast track your results (because of your diagnosis), so you should find out in 2 weeks. Keep us posted . Sending hugs xo
