Had my lumpectomy in October 2025. I was surprised how little pain I experienced. I did use Tylenol for 3-4 days and those little ice packs were my best friends. Get plenty of those from your doc. I think you need to wait a few days before showering but after that you should be fine. Your doc will go over all of that.
I did do 5 rounds of radiation with zero side effects.
I'n now on Letrozole as my cancer was estrogen receptive. Besides some mild hot flashes - I'm feeling normal.

You got this! Sending you a big hug!
