An oncology RN is a nurse who works in patient care for individuals who have been diagnosed with cancer or who are at risk of getting cancer. As an oncology RN, you work with patients on treatments, administering medication, counseling on how to live with the disease, and more. You also help to administer chemotherapy at hospitals and specialized treatment centers. In this career, you are often with the same patients from diagnosis to remediation, and you also interact with the families of your patients, so this is a critical role regarding both patient and family care.
