Bladder cancer, also known as urothelial carcinoma, is a type of cancer that affects the cells lining the bladder. The disease is often characterized by the presence of abnormal cells that grow and spread uncontrollably. Other synonyms for bladder cancer include transitional cell carcinoma, urothelial cancer, and carcinoma of the bladder. While the disease is usually treatable, early detection is crucial for effective management. Symptoms of bladder cancer may include painful urination, blood in the urine, and frequent urination. If you experience any of these symptoms, seek medical attention immediately to receive the proper diagnosis and treatment.
