Cigarette smoking is the most important cause of the disease. Smokers are more than twice as likely to get bladder cancer as nonsmokers. When cigarette smoke is inhaled, many of the toxins it contains are absorbed into the bloodstream, filtered by the kidneys, and excreted into the urine. As a result, the bladder lining is subject to prolonged contact with carcinogens.
A variety of industrial toxins can also injure bladder cells, eventually producing cancer. In the past, workers in the rubber, paint, electric, and textile industries were at substantial risk, but contemporary workplace safety regulations have greatly improved matters. Radiation therapy for prostate cancer appears to increase risk for bladder cancer years later. Some simple steps to reduce risk are to quit smoking, review work history for possible exposures to cancer-causing chemicals, and eat right. Although the details vary, studies agree that a high intake of fruits and vegetables appears to reduce the risk of developing bladder cancer, while a high-fat diet seems to increase it. A 2010 study also implicated red and processed meat as factors in bladder cancer risk.And although prevention is the best approach, this issue of Harvard Men’s Health Watch also discusses the diagnosis and management of this important disease.
