What is bladder cancer?
Simply put, bladder cancer is cancer that starts in the bladder. In order to do its job, the bladder has several different types of cells, and cancer can start with abnormal changes in any of those cell types.
The most common type—transitional cell or urothelial carcinoma—starts in the cells that line the inside of the bladder. Other common types include squamous cell carcinoma, which can occur because of frequent bladder infections, and adenocarcinoma, which starts in the glands in and around the bladder.
Who is at risk for bladder cancer?
Two of the biggest risk factors for bladder cancer are smoking and age—90 percent of bladder cancer diagnoses are in people over age 55. Other risk factors include:
- Exposure to certain harmful chemicals
- Family history of bladder cancer
- Chronic bladder infections or bladder stones
Some risk factors can't be controlled—your genetics can affect your risk for bladder cancer, and men get bladder cancer more often than women. But some risk factors are within your control:
- Quit smoking
- Drink lots of water
- Eat plenty of vegetables and fruits
There's no known way to guarantee you'll never get bladder cancer, but making small, healthy choices every day can reduce your risk—and help protect your overall health.
