      FAQ

      What should I expect during my first appointment, and what should I bring?

      Your first appointment is scheduled for one hour to review your completed tests and results. Additional imaging or procedures may be needed to support your diagnosis or determine next steps in your treatment plan. We may review medications, pretreatment recommendations and resources to ensure you have the support needed throughout your cancer care journey, including support groups, financial counseling and community resources.

      Bring any medical records from non-Mayo Clinic Health System facilities. If needed, complete a medical records release form to authorize the transfer of health records from another health care facility to us. Visit our Medical Record Forms page for this form and other forms in multiple languages.

      What are my payment options, and do you offer financial assistance?

      Visit the billing page of your preferred location for information on insurance, billing and payments.

      We serve patients in difficult financial circumstances and offer financial assistance to those who have an established need to receive medically necessary services. Learn more about financial assistance options.

      Can you provide a second opinion?

      Yes — simply call the appointment number at your preferred Oncology location. See What should I expect during my first appointment? for tips on how to prepare.

      What follow-up care do you provide after treatment?

      Our compassionate cancer care team extends beyond our oncologists. We partner with colleagues in a variety of areas to offer customized care specific to your individual needs. From your cancer diagnosis to survivorship resources, you're not alone. We're there every step of the way to help you understand your condition, coordinate care, and provide you with the tools and resources to manage it.

      Do you have an after-hours number in case of emergency?

      Always call 911 in case of an emergency. For after-hours help with other issues, get virtual care 24/7 through the Primary Care On Demand app or review our convenient care options.
