Bladder Polyp
A bladder polyp is a small growth that projects from the lining of the bladder. These polyps can be benign or may represent early bladder tumors, so proper evaluation is important. Many bladder polyps are found incidentally on imaging done for urinary symptoms or other abdominal concerns. Some individuals have no symptoms, while others may experience blood in the urine or urinary problems.
What is it?
A bladder polyp is an abnormal growth arising from the inner lining of the bladder. Polyps may be inflammatory, related to irritation or infection, or they may represent early forms of bladder tumors. Imaging can detect suspicious areas, but cystoscopy is often needed to see the polyp directly and determine whether it should be biopsied or removed.
Radiologists evaluate the size, shape, and location of a bladder polyp, as well as any signs of bladder wall thickening or obstruction. Some polyps are small and benign, while others may require further investigation to rule out cancer.
Important to Know
Bladder polyps vary widely in significance. Some are harmless inflammatory growths, while others can represent early bladder cancer. Smoking, chemical exposure, and chronic bladder irritation increase the risk of malignant bladder lesions, making follow-up important.
Red flag symptoms include visible blood in the urine, urinary urgency or pain, recurrent urinary tract infections, or sudden changes in urinary habits. These symptoms should prompt evaluation to ensure the polyp is not cancerous. Cystoscopy is often recommended, even if imaging detects only a small lesion.
