Bladder cancer is any of several types of cancer arising from the tissues of the urinary bladder.[1] Symptoms include blood in the urine, pain with urination, and low back pain.[1] It is caused when epithelial cells that line the bladder become malignant.[4]
Risk factors for bladder cancer include smoking, family history, prior pelvic radiation therapy, frequent bladder infections, and exposure to certain chemicals.[1] The most common type is transitional cell carcinoma.[1] Other types include squamous cell carcinoma and adenocarcinoma.[1] Diagnosis is typically by cystoscopy with tissue biopsies.[5] Staging of the cancer is determined by transurethral resection of the bladder tumor (TURBT) and medical imaging.[1][6][7]
Treatment depends on the stage of the cancer.[1] It may include some combination of surgery, radiation therapy, chemotherapy, or immunotherapy.[1] Surgical options may include transurethral resection, partial or complete removal of the bladder, or urinary diversion.[1] The typical five-year survival rates in the United States is 77%, Canada is 75%, and Europe is 68%.[2][8][9]
Bladder cancer, as of 2018, affected about 1.6 million people globally with 549,000 new cases and 200,000 deaths.[3] Age of onset is most often between 65 and 84 years of age.[2] Males are more often affected than females, with the lifetime risk in males being 1.1% and 0.27% in females.[10][2] In 2018, the highest rate of bladder cancer occurred in Southern and Western Europe followed by North America with rates of 15, 13, and 12 cases per 100,000 people.[3] The highest rates of bladder cancer deaths were seen in Northern Africa and Western Asia followed by Southern Europe.[3]
