When a patient is diagnosed with cancer he or she can become overwhelmed. Undergoing various treatments and dealing with healthcare professionals from different specialties like radiologists, pharmacists, and oncologists can be a lot to handle. Because of this, a new nursing sub-specialty has developed—the Nurse Navigator. A nurse navigator will offer medical guidance, act as a support group, and walk patients and their families through the cancer treatment process. Navigators who work with cancer patients already have nursing experience, but take navigation-specific classes to become fully qualified.
