Bladder Cancer Types
Bladder cancer types include transitional cell carcinoma, squamous cell bladder carcinoma, and adenocarcinoma. The most common among the bladder cancer types is transitional cell carcinoma. Bladder cancers can also be classified as belonging to one of two bladder cancer types: superficial bladder cancer or invasive bladder cancer. Metastatic bladder cancer is bladder cancer that has spread outside of the bladder.
Bladder Cancer Types: An IntroductionThe wall of the bladder is lined with transitional cells and squamous cells. The types of bladder cancer affect these cells differently:
- More than 90 percent of bladder cancers begin in the transitional cells. This type of cancer is called transitional cell carcinoma.
- About 8 percent of people with bladder cancer have a second type known as squamous cell bladder carcinoma.
- About 2 percent of people with the condition have a third bladder cancer type, referred to as adenocarcinoma.
Bladder cancers are also identified as superficial or invasive. When the cancer has spread outside of the bladder, it is known as metastatic bladder cancer.
