  Bladder Cancer
Bladder cancer is an abnormal growth or tumor arising from the lining of the bladder.
Smoking is a well known risk factor in causing bladder cancer because the carcinogens in cigarette smoke pass from the lungs into the blood stream, and are concentrated by the kidneys into the urine.
The pathology results from the transurethral resection of the bladder tumor may reveal that the tumor is either high grade (fast growing) or that its stage is "invasive." In this situation, the tumor is considerably more dangerous and potentially life threatening because it has the biological potential to spread to other areas of the body.
