Inability to urinate
In some cases, patients may not be able to urinate properly, have a reduced flow of urination, or their urinary tract becomes blocked by bladder cancer. Thus, urinating too much or not being able to urinate at all are both alarming signs that should not be neglected. In some cases, patients may be obstructed for too long, and start filling their urinary bladder with too much liquid. This sometimes requires an urgent medical procedure to empty the bladder and clear the emergency.
