Statistics is just a reference, not necessary to exactly apply to an individual because many variables, e.
g., age, Rx, health status, lifestyle, personal/social support, etc. are in play to decide ultimate individual outcome. But largely, the 5-yr survival for stage 1 (within bladder
lining) is about >90%; stage 2 (into bladder muscle), >70%; stage 3, about 50%; stage 4, about 5%.
