Which professional is primarily responsible for diagnosing and treating cancer?

The oncologist is primarily responsible for diagnosing and treating cancer. This medical professional specializes in oncology, which is the study and treatment of cancer. Oncologists are trained to evaluate diagnostic tests, determine the stage of cancer, determine treatment plans, and monitor patients throughout their cancer journey. They are critical in not only finding the right treatment, which may include chemotherapy, radiation, or surgery but also in coordinating care with other specialists to provide comprehensive support to the patient.

Surgeons may play a key role in the surgical treatment of cancer but are not solely responsible for the overall management and treatment of the disease. Nurse practitioners can manage various aspects of patient care, including education and symptom management, but typically work under an oncologist's guidance in cancer care settings. Radiologists typically focus on interpreting imaging studies and may assist in diagnosing cancer, but they do not provide direct treatment for the disease. The oncologist's extensive training and focus on cancer care make them the primary professional responsible for diagnosing and treating cancer patients.
