This treatment is used to fight certain cancers by boosting your body’s natural defenses — your immune system.

It may be given:

  • Intravenously, or through a vein
  • Orally, by mouth
  • Topically, through a cream you rub onto your skin

Immunotherapy may be part of a care plan that includes other treatments, such as chemotherapy or radiation. We’re learning more about the value of immunotherapy in cancer treatment, but it is still not as widely used as surgery, chemotherapy, and radiation.
