What causes the bladder wall to thicken?  My husband had colon cancer, then liver cancer and finally lung cancer. They sy he is doing well, but he had a MRI, and said he had some thickening in the bladder wall. Is this going to be serious?  thanks!! Jan
Thanks for your question on Chat Doctor. I can understand your situation and problem. There are many causes for bladder wall thickening.  The common ones are1. Chronic cystitis (chronic infection of bladder)2. Senile changes due to progression of age.3. Malignant involvement of bladder.etc in my opinion if he is not having any bladder symptoms like lower abdominal pain or blood in urine or painful urination, than no need for further investigation. Just get done repeat MRI after 6 months. And if he is symptomatic than get done cystoscopy and biopsy to rule out malignancy.
