My dad was diagnosed with Cholangiocarcinoma on Jan. 3rd and died 11 weeks later. He was a Phantom (F-4) pilot and flew two tours in Vietnam. He did survival training deep in the Southeast Asia swamps. Until age 73, he was one of the healthiest men I knew. He retired from teaching public school with hundreds of unused sick days. He had never been on a prescription drug. Yet this cancerous tumor took his life so quickly. And it was not an easy way to go. Bleeding, fever due to infections, abnormal weight loss, bouts of severe pain. Please help us put this illness on the presumptive illness list. It will mean so much to protecting future military personnel and financially compensating (very modestly) surviving spouses who suddenly find themselves alone.
