In 2009 I was diagnosed with Stage II melanoma on the inside of my knee and had it surgically removed. It had not spread to the sentinel lymph nodes. In 2014 I found a knot in my leg which turned out to be a tumor of melanoma. The cancer stayed dormant for just over 4 years. The melanoma spread through my lymphatic system and into my lungs and liver which means I was stage IV. My oncologist was Steven O'Day a world renown melanoma expert. I was treated with 4 courses of Yervoy (Ipi) and then went through a clinical trial of PD-1 which later was approved by the FDA as Keytruda (Pem). I am now past a 2 year mark of being in remission. Words do not express the gratitude that I have for Dr. O'Day and these new immunology treatments. Please let me know if there is anything I can do or help in any way. Thank you.
