I had estrogen positive BC, a 2.5 cm tumor, and also in my lymph nodes. My surgeon explained that because of the size and location of the tumor, I was a perfect candidate for a simple lumpectomy, which made me very happy. Studies show that recurrence of BC happens just as often with a mastectomy as it does a lumpectomy.
I also asked my surgeon if she were to find the BC in lymph nodes, would they go ahead and put a port in. I didn't want a second surgery for that. A port is necessary (in most cases) for chemo. They did find it in my nodes, so I had the port put in at the same time I had a lumpectomy.
If you actually do require a mastectomy, you'll want to find out what your reconstruction options are, if you are interested in that.
I'm sure others will have suggestions also. Be sure you really like this surgeon and that you have checked them out thoroughly. There's nothing wrong with visiting more than one.
I have had my final radiation oncologist visit and been released just this week. My treatment ended 5 years ago tomorrow!!!
HUGS. You'll get through this. It's not as bad as you might imagine.
