Opdivo (nivolumab) is a cancer medicine that works with your immune system to interfere with the growth and spread of cancer cells in the body. Opdivo is used to treat a certain type of melanoma (skin cancer) that cannot be treated with surgery, or that has spread to other parts of the body.
Opdivo is also used to treat a certain type of non-small cell lung cancer. Nivolumab may increase the chance of a longer survival time in people with this type of lung cancer. Opdivo is used for melanoma or lung cancer only if your tumor has a specific genetic marker that your doctor will test for.
