Bladder Cancer Stages Explained - Anatomy and Progression Diagram #3692121 (License: Personal Use)

The diagram depicts the human urinary bladder with labeled anatomical features including the ureters, urethra, and ureteral openings. It illustrates two key cancer stages: Stage 0, where abnormal cells are confined to the inner lining (non-invasive), and Stage IV, where the tumor has grown deeply into the bladder wall and possibly spread to adjacent organs or lymph nodes. A magnified inset highlights the microscopic appearance of early-stage carcinoma in situ.

Used on oncology, urology, or patient-education web pages to explain bladder cancer staging for patients, caregivers, or medical students; supports content about diagnosis, treatment planning, and prognosis.
