Double Masectomy or radiation

I was faced with the same decision and chose the lumpectomy only. My cancer was multifocal and included lcis, and there were more rumours found than was seen in the screening, which made me consider DMX. But at the end of the day I didn’t feel like having a huge operation right now if I didn’t have to, and the doctors said there was 80% chance I won’t ever get a recurrence. So I decided to keep an eye on things and deal with the 20% risk if it happens. I didn’t have any bc genes either.
