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.

Updated visitor policy: For the safety of our patients and staff, no visitors will be permitted into the clinic. Family members and caretakers may participate in the appointments remotely by phone or video conference if desired. All patients and staff will be required to wear a face covering(or mask) that covers the nose and mouth. This new policy reflects the recent recommendations by the CDC to reduce community-based transmission.

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.
