Surgical Consultations For Digestive Cancer Without The Wait

Appointments Within Five Days for Patients with Cancer

At AdventHealth Digestive Institute, we know that after being diagnosed with cancer, patients want and often need to begin treatment quickly. So we make it a priority to offer appointments for cancer surgery consultations within five business days, and often earlier.

Patients who are newly diagnosed with cancer, or have just found out they have cancer again, qualify for this priority access. Our surgeons will make themselves available to see you right away, even for a second opinion. We want to help you start your treatment as soon as possible.
