No one wants to be known for cancer, but a treatment can be. Keytruda is known to treat cancer. Fdaapproved for 16 types of cancer, including certain earlystage and advanced cancers. One of those cancers is earlystage non small cell Lung Cancer. Keytruda may be used with certain chemotherapies before surgery when you have earlystage Lung Cancer, which can be removed by surgery, and then continued alone after surgery to help prevent your Lung Cancer from coming back. Keytruda can cause your Immune System to attack healthy parts of your body during or after treatment. This may be severe and lead to death.
