Immunotherapy – This is another type of treatment that involves giving the patient some medicines that help to boost his immune system. It further helps to prevent the spread of cancer to other areas of the body. It acts as a form of a cancer vaccine that can prevent the growth of cancer cells.

2. Surgical Oncologist:

It can also remove the surrounding tissue area to prevent cancer from spreading to other areas of the body. The surgical oncologist may also perform a biopsy to identify if the patient is suffering from cancer. Oncologist removes a portion of the tissue for a cancer test.

3. Radiation Oncologist:

A radiation oncologist uses powerful x-rays and other forms of particles to reduce the growth of cancer cells in the body.
