Blackrock, first let me say thanks for your service. Although I have had very little interaction with the VA, I have a friend that believes his Parkinson's disease of 4-5 years was has a causation from Agent Orange in the 60's. He basically has just had a runaround with no one committing either yes or not. At the same time he does have a friend that did some satisfaction or settlement in a similar situation (Viet Nam service also). Who knows what causes any of this? I never smoked which is one of the markers but, I did have an uncle that had BC. Genetics, and exposure to chemicals have to be a part of any cancer. Wish I could be more positive but, I am just passing along what my observations are.
