Urinary bladder cancer is a type of cancer that originates in the cells of the bladder lining. It is characterized by the uncontrolled growth of abnormal cells, which may form tumors within the bladder. Symptoms often include blood in the urine, frequent urination, pain during urination, and pelvic discomfort. Diagnosis typically involves a combination of imaging tests, such as cystoscopy and CT scans, along with biopsy to confirm the presence of cancerous cells. Treatment options may include surgery, chemotherapy, radiation therapy, immunotherapy, or a combination of these approaches, depending on the stage and aggressiveness of the cancer. Early detection and prompt treatment are crucial for improving outcomes and quality of life for individuals with urinary bladder cancer.
