There’s a lot of good stuff in your post, even if you might not be quite in the right place to cheer just quite yet.
Brilliant news on the clear margins. You can cross off possible mastectomy from your list, so that’s got to be a good thing. I know that was one thing I was dreading more than chemo and I was delighted when I also got my clear margins news.
Grade 1 means usually slow growing, not a big difference from normal cells, Grade 2 is more aggressive and Grade 3 is very aggressive. So Grade 2 is also good news. Not fantastic news, but good news all the same. Grade 3 would almost certainly have meant definite chemo, Grade 2 is one of those that may go either way.
Er+ and Pr+ is common, 75% of cancers are hormone-receptive, and that means you also have another weapon against recurrence in Tamoxifen or aromatase inhibitors, so that’s also good news. Triple negative ladies tend to get very worried that they don’t have the extra weapon.
HER2 negative is brilliant, that means you won’t have to have Herceptin, and certainly where I’m being treated if you have to have Herceptin then you DEFINITELY have to have chemo. Yes, still waiting, but Herceptin isn’t without potential side-effects including possible heart damage, so HER2- is ALSO good news.
It’s the size, 28mm, that makes chemo a possibility, and as yours is a size that is on the cusp of whether it generally gets chemo or not it’s something you’ll have to discuss with your oncologist. You might find that you are given the choice of whether to have chemo or not, and that’s a tough decision, or he or she will recommend one course or the other. There won’t be anyone on here who can suggest that one or the other is more likely, so yes, it’s the waiting room for you too. If you’re the sort of person who wants to know stuff you might want to do a bit of investigating the sorts of chemo that might be given, the SEs, the length of treatment, etc etc. I’m assuming your nodes are clear (and that’s THE BEST news!) as if they weren’t you’d be certainly up for chemo. Do some investigating about FEC, as from what I’ve picked up from here that’s the most common chemo regime that is used.
You have lots of good news in all of that lot, so when you’re ready to think about it from that perspective, there’s things you can smile about. Love and hugs to you and your mum, and when you get to talking to her about it, there’s lots of reassurance you can give her.
