C64-C68: Malignant neoplasms of urinary tract

C67: Malignant neoplasm of bladder

Malignant neoplasm of the bladder, also known as bladder cancer, is a group of conditions where abnormal cells in the bladder grow and divide in an uncontrolled way, forming a mass called a tumor. Symptoms often include blood in the urine (either noticeable or only detected in a urine test), frequent urination, or pain during urination, though some people may not exhibit any symptoms in the early stages. There are various types of bladder cancer, including transitional cell carcinoma, squamous cell carcinoma, and adenocarcinoma, named based on the type of cells that become malignant. The condition varies in its rate of progression and can either remain confined to the bladder's lining or potentially spread to other nearby or distant parts of the body. Risk factors commonly include smoking, chemical exposure, and older age among others. Regular check-ups can help in early detection of these conditions.
