What are some of the side effects of uterine cancer treatment?

It depends: Surgery means healing and some pain. The length of recovery depends on surgery via larger incision or minimally invasive or robotic. Any surgery can have infection, bleeding or damage to adjacent organs as a "side effect" complication. If you mean radiation, that depends on the amount and how it is delivered but can affect your bowels and bladder. Chemo is usually not used but can be unpleasant.
