Bladder cancer clinical trials study investigational medications alone, or in combination with other study medications, or standard of care therapy.
The most common type of bladder cancer is urothelial carcinoma. This type of cancer begins when cells inside the urinary bladder start to grow rapidly. As more cancer cells build up, they form a tumor, which can grow through the layers of the bladder and spread to other areas of the body. When the cancer has not grown into the muscle layer of the bladder it is called non-muscle invasive bladder cancer.
