I hope you have the choice to stay in. It should not be out of your hands. It's major surgery and if you aren't okay to leave you shouldn't be made to leave.
I had a L? Mastectomy end of Sept 2025. I would not have been ready to go home after 1 night. I probably could have managed after 2 or 3 days, but I ended up going home on the 5th day post surgery. I still had drains in and had them for 2 more weeks. I did not mind staying in. I was in a private hospital in a private room so it was nice and quiet. I liked not having to worry about food! I needed good pain relief. As long as they don't force you out when you are not ready to leave.
