Dr Howington did surgical removal of my lower lobe left lung October 9th 1997 in Little Rock Arkansas at UAMS. It was hoped that the lung contained primary lung cancer but it was in fact metastatic melanoma. We were frightened that I may not live more than a short time. He was skillful and very very kind. I want to get the message to him that I am, in fact, still living. 73 years old and very active. He might remember that the tumor was behind my heart and about the size of a golf ball. His skillful care gave me time to get into a clinical trial and after five years of that autoimmune therapy the melanoma has not come back. My name is Darrel Clare and I am so thankful for Dr Howington.
