A bladder tumor is an abnormal growth of cells in the bladder, which is the organ that stores urine. These tumors can be benign (non-cancerous) or malignant (cancerous). Symptoms may include blood in the urine, frequent urination, and pain during urination. Diagnosis typically involves imaging tests, such as CT scans or ultrasounds, and a procedure called a cystoscopy, where a doctor examines the bladder with a thin tube. Treatment options vary based on the tumor type and stage, including surgery, chemotherapy, or immunotherapy. Early detection is crucial for better outcomes.
