For those diagnosed with brain or spine tumors, Ascension Seton’s Cancer Care Collaborative offers a weekly multidisciplinary clinic. Patients can be referred to the clinic by their primary health care provider. They will be introduced to the dedicated patient navigation services we offer and may also be seen by a neuro-oncologist, a neurosurgeon, and a physical medicine and rehabilitation physician as well as a dietitian and health psychologist – all in one visit at the same location.
