  • Mixed Small Cell Carcinoma: A type of bladder cancer that contains both small cell and other types of cancer cells, making treatment more complex.
  • Small Cell Urothelial Carcinoma: A variant of small cell bladder cancer that originates from the urothelial cells lining the bladder.
  • Small Cell Variant of Urothelial Carcinoma: A rare form of bladder cancer where small cell features are present within the urothelial carcinoma, impacting treatment decisions.

What are the Symptoms of Small Cell Bladder Cancer?

Small cell bladder cancer presents with symptoms that are commonly seen in other types of bladder cancer. These symptoms may include changes in urinary patterns, blood in the urine, frequent urination, and pelvic pain. Additionally, some individuals may experience weight loss and fatigue.
