If you have advanced melanoma, your doctor might suggest immunotherapy. This treatment helps your immune system fight cancer more effectively. The most common type is called a checkpoint inhibitor. These drugs help your T-cells, which are part of your immune system, recognize and attack cancer cells. You usually receive these drugs through an IV at a clinic or hospital, and you don't need to stay overnight. Treatments are typically given every 2-3 weeks in cycles, allowing your body to rest between treatments. Side effects can vary. Some people might experience skin rashes, diarrhea, or fatigue, while others might have more severe reactions like inflammation of the lungs or pancreas. It's important to tell your doctor about any side effects you experience so they can help manage them. Scientists are still studying why these treatments work better for some people than others, but they believe it might be related to the amount of DNA damage in the cancer cells. Overall, immunotherapy offers hope for many people with advanced melanoma, but it's important to discuss the potential benefits and risks with your doctor.
