Bladder tumours

Bladder tumours - Growths originating in the inner lining of the bladder. Many are papillomas (small wart-like growths), which tend to recur and will eventually become cancerous. Other, more malignant, growths may extend not only into the bladder cavity but may also spread through the bladder wall to involve nearby organs such as the colon, rectum, prostate gland, or uterus.

Bladder cancer is more common in smokers and workers in the dye and rubber industries. Haematuria (blood in the urine) is the main symptom of bladder cancer. A tumour may obstruct the entry of a ureter into the bladder, causing back pressure and pain in the kidney region, or may obstruct the urethral exit, causing difficulty in passing, or retention of, urine.

Bladder tumours are diagnosed using cystoscopy and biopsy of the abnormal area. If small, they can be treated by heat or surgically during cystoscopy. They tend to recur at the same or other sites within the bladder, so that regular follow-up cystoscopy is needed. Bladder tumours that have spread through the bladder wall may be treated by radiotherapy or by surgical removal of part or all of the bladder.
