Bob had rotator cuff surgery at the end of March 2015. While recovering from the surgery he began experiencing pain in his neck and left side. He thought this may have been due to wearing the sling and/or sleeping in his recliner. It was also discovered that a routine chest x-ray after surgery showed cloudiness in one of his lungs. A repeat x-ray and CT scan were done in May. Bob was diagnosed in June 2015 with Stage IV Non-small Cell Lung Cancer - Adenocarcinoma.
