We wanted to reassure you that Arizona Oncology remains open to provide medically necessary, life-sustaining care. In addition, our expert care team can now see patients through scheduled virtual appointments on a secure platform from the comfort and safety of your home.

Please note; only one caregiver is allowed to accompany during your appointment, no one under the age of 18, and no visitors in the infusion rooms, radiation and treatment areas. If you have flu-like symptoms, you should contact Arizona Oncology before visiting our clinics for scheduled appointments. This includes fever and symptoms of respiratory illness, such as coughing or difficulty breathing.
We ask that you follow our tips to stay healthy and to help do our part in prevention of spreading of these viruses.
