What to Expect

We may collect information from your referring physician such as demographic information, details about your treatment so far, insurance and medical records. Or we may ask you to bring this information.

Your first appointment will be an initial consultation with a radiation oncologist to discuss your cancer treatment options, review the benefits and side effects, and answer questions about radiation therapy.

If you and your radiation oncologist decide that external beam radiation therapy is best, learn more about the external radiation process.

Initially, you may be asked to arrive early for your appointment. You can expect to spend between one and a few hours at UMGCCC for each treatment. In most cases, you should be able to drive yourself home after treatment.

Care partners may attend your initial consultation appointment  and your exam room appointments with you if you wish. Please view the current visitor policy before your visit.
