Do people die from bladder cancer?

Sometimes: Bladder cancer can be deadly. The grade (microscopic features)and stage (extent of tumor) of cancer, as well as treatment received determine a person's risk of death. Low grade cancers are typically nonlethal, but not all high grade cancers are lethal.

Yes, however...: People die of bladder cancer. Luckily, the majority of bladder cancers are superficial, which are more easily treated. The ones we worry about are "muscle invasive" or where we have evidence that the cancer has spread beyond the bladder to other parts of the body.
