The causes of bladder cancer are not fully understood, but smoking, exposure to certain industrial chemicals (like in paint, textile, and rubber production), chronic bladder inflammation, radiation, genetic predispositions, and parasitic infections in tropical regions are known risk factors.
Typical bladder cancer symptoms include painless blood in the urine and frequent urination, similar to a bladder infection. In advanced stages, weight loss, abdominal pain, and leg swelling can occur.
Deeply growing bladder tumors are dangerous and require treatment within three months, usually by radical cystectomy combined with other therapies. This large and complex urological surgery, however, carries numerous complication risks and requires special preparation.
