Hi and welcome, sorry for the reason you are here.
I am not real familiar with TAMIS, butt because there will be no incision, It sounds like your recovery will be quicker, probably just an overnight stay in the hospital vs several nights with other types of surgery.
Do your doctors suspect cancer? Have you had any other tests like blood work or CAT scan?
This is just an assumption on my part (I am not an MD), because of the type of procedure, TAMIS, I don't think your doctors are assuming it's cancer. Usually when dealing with cancer, there will be some incisions and they want to take out near by lymph nodes looking for possible spread. I don't think they can do this with this type of surgery. Again just an assumption on my part. If it is cancer, it probably is a very early stage. Stage O or stage 1. Very curable.
Anyway good luck, please keep us posted after your procedure.
