Brain tumors are benign or malignant lumps that grow in the brain. A tumor is an abnormal growth caused by cells reproducing themselves in an uncontrolled manner. Benign brain tumors have distinct boundaries and surgery alone may cure this type of tumor. A malignant brain tumor is life-threatening. It may be malignant because it consists of cancer cells, or it may be composed of benign cells but still called malignant because of its brain location. Ryken will answer questions on the health issues associated with brain tumors.

Ryken, a staff neurosurgeon and assistant professor with UI Health Care, received his medical degree from the UI College of Medicine. He completed his residency at the UI Hospitals and Clinics and a fellowship at the University of Cambridge, United Kingdom. He joined the staff of UI Health Care in 1998.
