Melanoma, Metastatic
"I received Keytruda for about 20 months for metastatic melanoma. After the first infusion we noticed that the visible spots on my back had gotten lighter in color and softer.

After over a year of scans that revealed that Keytruda was working for me, a lymph node in my chest began growing. A PET scan revealed that the spots on my back had been killed by the medication, and it had also destroyed a number of small nodules in one lung. But the lymph nodes in my chest were positive. My oncologist believes that my cancer has mutated, and Keytruda stopped working.

Side effects were mild. Some mild fatigue, and at the beginning a very fine itchy rash that was not annoying at all. I just wish it had worked for me a little longer."
