Factors that may increase your risk of bladder cancer include:
June 19, 2012
- Smoking. Smoking cigarettes, cigars or pipes may increase your risk of bladder cancer by causing harmful chemicals to accumulate in your urine. When you smoke, your body processes the chemicals in the smoke and excretes some of them in your urine. These harmful chemicals may damage the lining of your bladder, which can increase your risk of cancer.
- Increasing age. Your risk of bladder cancer increases as you age. Bladder cancer can occur at any age, but it's rarely found in people younger than 40.
- Being white. Whites have a greater risk of bladder cancer than do people of other races.
- Being a man. Men are more likely to develop bladder cancer than women are.
- Exposure to certain chemicals. Your kidneys play a key role in filtering harmful chemicals from your bloodstream and moving them into your bladder. Because of this, it's thought that being around certain chemicals may increase your risk of bladder cancer. Chemicals linked to bladder cancer risk include arsenic and chemicals used in the manufacture of dyes, rubber, leather, textiles and paint products.
- Previous cancer treatment. Treatment with the anti-cancer drug cyclophosphamide (Cytoxan) increases your risk of bladder cancer. People who received radiation treatments aimed at the pelvis for a previous cancer may have an elevated risk of developing bladder cancer.
- Taking a certain diabetes medication. People who take the diabetes medication pioglitazone (Actos) for more than a year may have an increased risk of bladder cancer. Other diabetes medications contain pioglitazone, including pioglitazone and metformin (Actoplus Met) and pioglitazone and glimepiride (Duetact).
- Chronic bladder inflammation. Chronic or repeated urinary infections or inflammations (cystitis), such as may happen with long-term use of a urinary catheter, may increase your risk of a squamous cell bladder cancer. In some areas of the world, squamous cell carcinoma is linked to chronic bladder inflammation caused by the parasitic infection known as schistosomiasis.
- Personal or family history of cancer. If you've had bladder cancer, you're more likely to get it again. If one or more of your immediate relatives have a history of bladder cancer, you may have an increased risk of the disease, although it's rare for bladder cancer to run in families. A family history of hereditary nonpolyposis colorectal cancer, also called Lynch syndrome, can increase your risk of cancer in your urinary system, as well as in your colon, uterus, ovaries and other organs.
Bladder cancer is a type of cancer that begins in your bladder — a balloon-shaped organ in your pelvic area that stores urine. Bladder cancer begins most often in the cells that line the inside of the bladder. Bladder cancer typically affects older adults, though it can occur at any age.
The great majority of bladder cancers are diagnosed at an early stage — when bladder cancer is highly treatable. However, even early-stage bladder cancer is likely to recur. For this reason, bladder cancer survivors often undergo follow-up tests to look for bladder cancer recurrence for years after treatment.
