Waiting Time for Appointments
Because patients often are anxious about a cancer diagnosis, our referral specialists strive to arrange appointments with appropriate physicians quickly. Frequently, patients may have to wait only a few days for an appointment. However, one- to two-week waiting times are not unusual, particularly in the case of less urgent conditions. Please know that we will respond to your patients' needs as efficiently as possible and expedite the appointment process to the best of our ability.
