Big hug darling, big hug 💟. The surgery was really scary for me too. It is a scary thing. It’s also what will most likely get rid of all the cancer, so at least the outcome will be worth it. Recovery doesn’t take too long, just follow doctor’s instructions and do the physio therapy exercises which should be provided.
I’m not too sure about your question, but I think I might just have read somewhere that they can do a mastectomy if they do a quick test of the lumps and if it turns out bigger than initially thought. About margins, they won’t know if they were clear til post surgery, I think. And all that also depends on your surgeon. Not all are willing or able to do all that. Also, ILC is more weblike from what I can remember having read, so not sure how plausible that would be. I think you should use the time and try to get another opinion. I know it’s stressful and costly, but it could save you a lot of money and stress in the long run.
Sorry if I’m not making much sense, I’m half asleep. Just wanted to send you a big hug and let you know we understand how you’re feeling. Good luck 💟
