Great that your nodes are clear, @Della ..... did he say if the 'margins were clear'? Maybe ask the Onc when you see them. They will have access to your Pathology report too. Fingers crossed you don't need the chemo - but they Onc will explain all that to you ....
Re Genomic Testing - I didn't have it done, but we did have it done earlier this year for my husband's cancer - to see if there were any mutations in his cancer that may enable more specific targeting with his chemo. Ask them the cost (as it can be a tad expensive.) Do you have children? The Braca Gene test is to see if you may have it & may pass it on to them - if 'yes', they could be tested too, if they wanted to find out. I don't have children, so didn't need that.
Re the copy of the results - when all your pathology results are 'in' .... ask for a copy of your pathology from your surgeon (or ask your breast care nurse to grab one for you!) It is good to have for your own records. Your Surgeon will also report back to your GP - so ask THEM for a copy of the surgeon's report too .... I just grab copies of whatever I see!! After you see the Onc, they will report back to your surgeon AND GP ..... lots of reports!!
The lymph node removal pain under your armpit can take a couple of months to settle .... mine did. It was also a tad 'numb' after that as well. I can't remember if I was Antibiotics - usually only if your wound goes red/sore, I think. Your surgeon should have checked your wound at the appt on Wed? Did he? If you are concerned at it being warm (which can be an indication of infection) either get checked out by your breast care nurse, or see your GP - don't put it off.
Re food .... just go back to eating whatever you enjoy & like - just with moderation. There is no rhyme nor reason for you getting BC in the first place - so you can't really blame your food habits on a 'guess' ..... vegans get BC, meat eaters get it - my husband was an incredibly fit triathlete who never ate any 'wrong foods' or drank booze & ended up with stomach cancer! So .. it is all just TOTALLY unfair! Don't deny yourself food that you like & enjoy. Specially if you can't afford to lose weight! (I'd give you some of mine, if I could! ;) )
Take care, keep busy doing what you love ..... try not to overthink the whole thing. xx
