"Have surgery on Tuesday" would be how I would write it on my to do list.

You're putting surgery on a To Do list?? I would probably say one of these: Have surgery Get an operation Have an operation Good luck with the surgery!

I am scheduled to undergo DIEP flap surgery. It is a type of reconstructive surgery, and I will be having the procedure on the planned date. I am scheduled to undergo DIEP flap surgery at Txdiepflap
