What is an oncologist?

An oncologist is a cancer specialist who specializes in diagnosing, staging, and treating cancer. If you are diagnosed with cancer, you need to consult with an oncologist to know more about your specific cancer, its type and stage, along with the location of the cancer and extent of growth in your body. 

What does an oncologist do?

Here are some of the diagnosis and treatment activities of an oncologist:

  • Perform cancer screening tests to diagnose cancer.
  • Provide a second opinion on your previous diagnosis.
  • Identifying the best treatment option for their patient
  • Explain treatment side effects and benefits to patients.
  • Oversee patient’s cancer treatment
  • Manage post-treatment care.

Types of Oncologists?

People diagnosed with cancer have to consult multiple oncologists on their cancer care team. Each specialist has to focus on different areas of your cancer treatment with a common goal. 

There are certain oncologists who specialise in certain treatments.

Surgical oncologists:

Surgical oncologists are surgeons who will perform surgery to remove tumors or cancer that hasn’t spread to other organs. Surgical oncologists also remove the surrounding tissues to prevent the recurrence of cancer in patients.

Medical oncologists:

Medical oncologists use treatments such as chemotherapy, hormonal therapy, and other targeted treatments to treat cancer.

Radiation oncologists:

These radiation oncologists are also cancer specialists. They use radiation therapy to treat cancer in their patients. Radiation is often used to shrink or destroy tumors or cancer cells to kill remaining cancer cells after the surgery. In some cases, radiation therapy alone or combined treatments are given to treat cancer.


Other oncologists who specialize in diagnosing and treating different types of cancer:

Gynecologic oncologists:

These oncologists offer treatments for gynecologic cancers such as cervical cancer, uterine cancer, and ovarian cancer.

Pediatric oncologists:

These oncologists provide treatments for cancer in children, such as childhood acute lymphoblastic leukemia, Ewing sarcoma, and childhood brain tumors.

Neurological oncologists:

These specialists treat patients who have brain cancer and cancer that affects the nervous system.

What is a medical oncologist?

The medical oncologist is a doctor who specializes in diagnosing and treating cancer using a variety of treatments such as chemotherapy, hormonal therapy, targeted therapy, immunotherapy, and many other treatments. Cancer patients mostly consult with a medical oncologist in the early stages/days of their cancer treatments and often consider the medical oncologist as their primary cancer specialist. 

This is because they often visit their medical oncologist during their cancer treatment journey. The majority of medical oncologists also specialize in hematology. This includes the treatment and diagnosis of blood cancer and blood disorders.

What is a surgical oncologist?

A surgical oncologist is a surgeon who diagnoses and treats cancer by performing surgery to remove cancer or a tumor that hasn’t spread to other body parts yet. Surgery is the common treatment performed by the surgical oncologist for the treatment of cancer. Surgeries are often performed when your biopsy shows any cancer cells, and they remove your tumor along with surrounding tissues to prevent cancer recurrence in your body again.

  • Discuss what to expect after the surgery.
  • Oversee the chance of recovery.
  • Treat any post-surgery complications.
  • Perform palliative care surgery to ease and smooth cancer symptoms in patients.

What types of surgeries do surgical oncologists perform?

There are two types of surgeries a surgical oncologist performs. 

1. Minimally invasive surgery:

In this procedure, the surgical oncologist might make several small incisions (cuts); they use a specialized tool to remove cancerous tissue. 

2. Open surgery:

In this procedure, the oncologist might make a large cut, also known as an incision, to remove the cancerous tumor from the body.

Key difference between medical and surgical oncologists

The main difference between medical oncologists and surgical oncologists is based on their treatment approaches. The medical oncologist treats cancer while using specific medications such as chemotherapy, immunotherapy, and targeted therapy, while the surgical oncologist treats cancer using surgical procedures, which mainly include tumor removal surgeries and biopsies.

When to consult a medical oncologist vs. a surgical oncologist?

You need to visit a medical oncologist or a surgical oncologist when your general physician guides you to consult an expert based on your condition.

Medical Oncologist:

You should consult a medical oncologist when you require medication-based treatments or therapy, such as chemotherapy, hormonal therapy, or immunotherapy. This consultation helps in managing these treatments along with deciding your long-term treatment goals. 

Surgical Oncologist:

You should consult a surgical oncologist when you require a biopsy or surgical removal of a tumor or you are considering surgical treatment options for your treatments.
