Oncologists are known as cancer doctors or specialists who diagnose and treat various types of cancer in different parts of the body. There are 3 main types of oncologists: medical oncologists, surgical oncologists and radiation oncologists.

• Medical oncologists use medicines to treat cancer. Examples of medical treatments include chemotherapy, hormone therapy and immunotherapy.
• Surgical oncologists remove tumours during an operation. They also take tissue samples (biopsies) from the body to be sent for testing.
• Radiation oncologists use radiation to treat cancer. This is also sometimes called radiotherapy.

These different types of oncologists often work together as a team to diagnose, treat and care for people with cancer.
