I was sent home after my lumpectomy and had 1 1/2 hour drive which normally wouldn't have been so bad, but I don't do well with anesthetic and should have remained in hospital. For my second surgery which was partial mastectomy on both sides, I did stay overnight. I found out that if you are a Medicare patient, that you can tell them you need to stay and that is allowed. With the amount of stitches and having tubes in, I think it's a fair request to stay overnight so you can get your bearings. My surgery lasted 6 hours and I was in no shape to return home and am glad I stayed overnight. All the best to you.
