C64-C68: Malignant neoplasms of urinary tract

Malignant neoplasms of the urinary tract refer to a group of cancers that originate in the organs responsible for urine production and excretion, including the kidneys, the bladder, the ureters, and the urethra. These types of cancers are typically characterized by uncontrolled growth of abnormal cells within these organs. The exact cause of these cancers is generally unknown, but several risk factors such as smoking, exposure to certain chemicals, and a history of urinary tract infections could contribute to their development. Symptoms may include blood in the urine, frequent urination, pain during urination, and lower back pain. While these cancers may initially develop without causing significant symptoms, they often progress over time, potentially leading to more severe complications if not detected and managed promptly. The urinary system — specifically the kidneys, bladder, and the urethral tube — is generally the most affected by these conditions.
