My 73 Yr Old Male Friend, Vietnam Vet, Agent Orange,

My 73 yr old male friend, Vietnam vet, agent orange, had a recent negative stool test. And while IMPATIENTLY waiting more than 5 weeks and counting for the VA to schedule a colonoscopy, he now has blood in his stool. Also recently found three shattered glass like tumors in his lungs. Guess I'm just wondering how much time we have left.
