Only about 33 percent of people know that smoking is a leading risk factor for the disease, according to a new study published in The Journal of Urology.
Here's a perfectly good reason to quit: Smoking causes bladder cancer.
The American Cancer Society estimates that smokers are twice as likely to get bladder cancer as nonsmokers.
Bladder cancer is the fourth most common type of cancer in men and eighth most common in women.
About 53,000 men and woman are diagnosed with bladder cancer each year and about 14,000 die annually of the disease.
In recent decades, there has been a steady increase in the incidence of bladder cancer.
“A smoker’s bladder is continuously exposed to carcinogenic substances which, over time, can affect the bladder lining and potentially lead to cancer,” said Tomas Griebling, MD, associate professor of urology, vice chair of urology and assistant scientist in the Center on Aging at the University of Kansas School of Medicine in Kansas City.
“If the threat of lung cancer isn’t serious enough to inspire a patient to quit smoking, perhaps the thought of losing your bladder to cancer will be.”
Along with smokers, people who work with dyes, metal, paints, leather, textiles and organic chemicals may be at a 20 to 25 percent higher risk. People who have chronic bladder infections may also be at higher risk.
There are several symptoms of bladder cancer, but painless blood in the urine (hematuria) is the most common.
Because blood in the urine can be an indication of other conditions, it is important to seek medical attention.
Other symptoms of bladder cancer may include frequent urination and pain upon urination (dysuria).
Bladder cancer can be treated by removing the tumors, administering intravesical chemotherapy and immunotherapy, or cystectomy (complete removal of the bladder).
Bladder cancer is most treatable when caught early.
