The Neuro-Oncology team is made up of doctors from various disciplines and nurses with specialized training. The multidisciplinary team approach helps to ensure that patients receive the most comprehensive and highest quality care. We also work with other clinical service teams and teams that provide psychosocial support, so that patients and their families are cared for in every way.
