Keytruda is a medication used to treat various types of cancer. It is an immunotherapy drug that works by blocking the activity of a protein called PD-1, which helps the immune system recognize and attack cancer cells. Keytruda is used to treat several types of cancer, including melanoma, non-small cell lung cancer, head and neck cancer, classical Hodgkin lymphoma, urothelial carcinoma, microsatellite instability-high cancer, gastric cancer, cervical cancer, and primary mediastinal large B-cell lymphoma [3]. Keytruda has been approved by the FDA since 2014, and it has been shown to be effective in treating many different types of cancer [2]. It is important to note that Keytruda is not suitable for everyone, and it may have side effects. Therefore, it is important to discuss with your doctor whether Keytruda is a suitable treatment option for you.
