How do you know if you have bladder cancer?

Agreed with Zachary Baker. But the astonishing part is that the symptoms are not just confined to the urinary area. Swollen legs, drastic weight loss, sudden urge to pee or even frequent peeing are also reasons behind the proliferation of bladder cancer.

Any change in the urine like blood in the urine, pelvic pain, or burning sensation during urinating calls for a check up because these are very common symptoms of bladder cancer.
