What are the types of bladder cancer?
Most bladder cancers form in the bladder’s inner lining (urothelium). This type of cancer is called urothelial carcinoma or urothelial carcinoma.
Other types of bladder cancer are small cell carcinoma, adenocarcinoma and squamous cell carcinoma. These less common cancer types are usually invasive, which means they have spread into deeper layers of the bladder wall and can be aggressive. They are sometimes a result of chronic irritation and inflammation.
