Washington University board-certified cancer specialists at Siteman Cancer Center collaborate with other Washington University specialists and the dedicated resources of Barnes-Jewish Hospital to provide the highest quality of care for patients with cancer. 

Cancer is many diseases – 80 or more – each with its own characteristics, treatment modality and outcome. Only highly specialized, individualized treatment plans work effectively, and our oncologists are experts in the medical management of a wide range of cancer types. 

Washington University cancer specialists treat:

In addition to the multi-specialty physician treatment team, each patient has the benefit of a designated multidisciplinary team of advanced practice nurses, oncology nurses, social workers, psychologists, psychiatrists, dietitians, home health and hospice specialists. Together with the resources of Barnes-Jewish hospitals, we provide compassionate and supportive care to our patients.
