How long does it generally take for uterine cancer to progress to stage 4?

Tumor stage: Declares extent by t, n and m characteristics at the start. Many confuse "stage" as a calendar and a step-wise progression that can be predictably timed...Thus your question. The uterus is divided between cervix and corpus or body. The body usually refers to the endometrial lining, and the stage by invasion into the muscle. Stage IV almost always means distant disease. Some start there.
