TIMELINE Landmarks in non-muscle-invasive bladder cancer

Bladder cancer is divided into two entities: non-muscle-invasive (NMIBC) and muscle invasive bladder cancer. NMIBC represents 75% of primary diagnoses and is characterized by frequent recurrence but a low risk of mortality. Throughout urological history, significant progress in detection, diagnosis, and treatment of NMIBC has been made. However, bladder cancer remains a heterogeneous disease with varying pathology, molecular background, diagnostic options, and subsequent therapies for the individual patient. Although significant progress has been made over the years, the improvement of bladder cancer outcomes remains the goal of future research.
