Gerald was diagnosed with adenocarcinoma of unknown primary on 6/13/2017 during a bronchoscopy and thoracoscopy with decortication. This was just supposed to be a routine procedure to remove built up fluid and scar tissue from around his left lung, which was thought to have been caused by a case of pneumonia. As a lifelong nonsmoker with clean blood work and scans, lung cancer wasn't even a blip on the radar until the thoracic surgeon saw the tumors on the scope. Pathology showed the cancer likely started in the GI tract, but after more scopes and scans, a primary site could not be pinpointed. On 7/3/2017, it was identified as colorectal adenocarcinoma. He begins chemotherapy on 7/19/2017.
