Cancer Institute Submission

It may surprise you to learn that 80% of U.S. cancer patients receive their cancer care in community cancer centers.

Community cancer centers are independent and NOT affiliated with a hospital or university. Community cancer centers are often closer to home, more convenient, more personal, and more likely to offer all of your services under one roof by a smaller group of staff that are all working as one team. Our doctors are more available to their patients and provide compassionate, personalized care. You can schedule an appointment much quicker at a community based cancer center.

Urology of St. Louis Cancer Institute is the only private practice in the St. Louis area that provides the same leading-edge, quality care that’s available at local hospital and university-based systems. The urologic oncologists at Urology of St. Louis Cancer Institute are experienced, fellowship-trained specialists who focus on the management of urologic cancers with advanced endoscopic, minimally invasive, robotic, and open surgical strategies.

Our goal is to make urologic oncology treatment and advanced cancer care more accessible and convenient, with one location in St. Louis and another in the Metro East. Patients will receive the quality care they need in a local, community-based setting.
