As you can see, patients with bladder cancer may suffer from extreme symptoms. They either increase their frequency of urination or become unable to pass urine when they want to. It may seem contradictory, but it is not. Increasing the frequency of urination is an irritative symptom, and it results from nervous triggers sending signals to the brain. Not being able to pass urine is an obstructive symptom, and it only appears when the tumor is big enough to cause obstruction.
