It is very distressing to have appointments postponed, especially without a reschedule date. At Mayo Clinic followup appointments are being either postponed or shifted to a tele-consult if no imaging is necessary.

@mom23boys to answer your question about why. You're right, it is to keep people safe and isolated at home, and to reduce the number of people in wait rooms and lobby areas to support social distancing for patients and staff. New dates will be scheduled as soon as possible. I encourage anyone who is experiencing high levels of anxiety to post a message to their team on the patient portal.

Your cancer care team can review your case and explain why the delay was chosen as the option for the moment. Please let them know if you need to speak with a social worker or therapist.
