Understanding Your Cancer Care Team at Compass Oncology

Patients who have been diagnosed with cancer may need to meet with several different Compass cancer care specialists during treatment and recovery. This guide should help make it easier to understand the role that each person may play in cancer care.


  • Oncologist: A doctor who has special training in diagnosing and treating cancer. Oncologists can specialize in several different types of oncology within this medical field.
  • Medical oncologist: A doctor who has special training in medical oncology, which includes diagnosing and treating cancer using chemotherapy, hormone therapy, biological therapy, and/or targeted therapy, as appropriate for each patient’s situation. A medical oncologist often serves in the role of the main health care provider for a patient undergoing cancer treatment. A medical oncologist also gives supportive care and may coordinate cancer treatments given by other specialists.
  • Hematologist: A hematologist is a physician who specializes in hematology, which includes disorders of the blood, bone marrow, and lymphatic systems. Most hematologists are also board certified in oncology and can treat many types of cancers, including blood cancers.

Radiation oncologists often work with a medical dosimetrist and/or a medical physicist to ensure treatment plans are uniquely tailored to both the patient and their cancer.  
  • Surgical oncologist: A surgeon who has special training in performing biopsies and other surgical procedures on cancer patients. In some cases, cancer surgery will be performed by a general surgeon or a surgeon who specializes in an area of the body such as breast, gastrointestinal, endocrine, etc.
  • Gynecologic oncologist: An oncologist who specializes in gynecologic cancers, which includes the diagnosing and treating cancers of the female reproductive organs, including ovarian cancer, uterine cancer, vaginal cancer, cervical cancer, and vulvar cancer.

Clinical Team Members

In cancer care, a nurse practitioner may manage the primary care of patients based on a practice agreement with a doctor.

Physician assistantPhysician assistants, also known as PAs, operate under the supervision of a doctor but share many of the same responsibilities of a medical doctor, with the exception of a few major procedures (including surgery). They practice medicine on teams with physicians, surgeons, and other healthcare workers. They’ll examine, diagnose, and treat patients in the same way a physician would, making them a valuable part of the cancer care team.
