What is an Oncologist?

An oncologist is a medical doctor who specializes in the diagnosis and treatment of cancer. Some oncologists treat patients with all forms of cancer, and others specialize in only one type of cancer. This can be confusing as you may have more than one type of oncologist participating in your care, for example, a medical oncologist who manages your chemotherapy and a radiation oncologist who manages your radiation therapy.

There are Several Primary Types of Oncologists

  • Medical oncologists - These physicians treat cancer with medications including chemotherapy, targeted therapies, immunotherapy, and coordinate other types of treatment. For many people, their medical oncologist acts as their main doctor during cancer treatment, and coordinates care received by other doctors and specialists. These doctors also manage the symptoms people may experience with cancer as well as side effects of cancer treatments.
     
  • Radiation oncologists - These are physicians who treat cancer with radiation therapy. They are responsible for "mapping" out the area on your body that will be treated with radiation and calculating the radiation dose and number of treatments that are optimal for your cancer. 
     
  • Surgical oncologists - These physicians are surgeons who treat cancer with surgical procedures. With lung cancer, it is common for thoracic surgeons to perform lung cancer surgery
  • Gynecologic oncologists - These oncologists treat primarily ovarian, uterine, and cervical cancers. In many cases, they perform the function of both medical oncologists and surgical oncologists in that they both perform surgeries for these cancers and design chemotherapy protocols.
  • Pediatric oncologists - These oncologists specialize in the treatment of cancers in children.
  • Hematologist-oncologists - The term hematologist-oncologist may be used as an alternative to the term oncologist alone, referring to doctors who have completed a fellowship in hematology and oncology. It is increasingly being used now to specify physicians who specialize in the treatment of blood-related cancers, such as leukemias, lymphomas, and myeloma.

Other Doctors Who Care for Cancer Patients

In addition to oncologists, there are often several other types of doctors as well as other specialists that may be involved in your care.

  • Pathologists are the physicians who analyze biopsy samples of tumors to determine the precise type of cancer. They may also interpret studies done to determine the molecular profile of a cancer.
  • Palliative care specialists - Palliative care physicians are doctors who specialize in improving the quality of life for people with cancer rather than directly treating a cancer. It's important to note that palliative care is not the same as hospice. Your medical oncologist may recommend that you see a palliative care specialist even if your cancer is curable in order to maximize your comfort during treatment.
  • Rehabilitation specialists - Now that so many people are surviving cancer, the concept of survivorship is finally being addressed. Rehabilitation specialists - such as those who are board-certified in physical medicine and rehabilitation - may design a program for you during or after treatment with the goal of returning you to health. The late effects of cancer treatments can range from physical disabilities to pain to posttraumatic stress in cancer survivors. These physicians may help coordinate treatments such as physical therapy and counseling to help you cope with these late effects.
  • Other specialties - Physicians from many other specialties are often involved in cancer care. For example, pulmonologists are lung specialists who often assist in helping patients with lung cancer, and gastroenterologists are doctors who specialize in the digestive tract and often help manage the treatment of esophageal cancers, stomach cancers, and colon cancers. 

Choosing an Oncologist

Many people wonder how to choose an oncologist when they are diagnosed with cancer. There are several factors to consider in making these choices. Studies suggest that doctors who care for greater numbers of patients with a particular cancer have better outcomes, and your choice of an oncologist may come down to choosing the best cancer center possible. If you have an uncommon type of cancer, or wish to take part in clinical trials, the larger cancer centers may offer more options. Other considerations include:

  • Your insurance coverage
  • Your location
  • Travel preferences

When you have cancer, it can be important to get a second opinion. In doing so it's often recommended that your second opinion doctor be part of a separate medical system and ideally part of one of the larger cancer centers.  Even if your second opinion (or third or fourth) recommends the same treatments, the opinion can help you feel more confident in the choices you have made for treatment.

Communicating with Your Doctors

As noted by scanning the lists above, you may have several different physicians helping to manage your cancer. It's important to talk with these physicians and understand clearly what symptoms and treatments are being managed by each one. Who do you call if you have a symptom at 2 am? Most often your medical oncologist will play the role of coordinator but it's important to establish this before your need help.

Preparing to See Your Oncologist

Before you see your oncologist and other doctors who will take care of you, it can be helpful to write down a list of questions to ask. Check out these tips for preparing for and improving your oncology visits
