I have been fighting with the VA for over 10 years about Herbicides and Tach Sites. I was stationed at A 7 Duce. I have had part of my right lung remover (cancer), mantel cell lymphoma and 6 more things of the herbicides list. The VA cant find any records showing that I have been exposed. VA Nurse intervened me and sent recommendation VA that she thinks I have been. Wondering if you or someone you know could give me some assistance. I was stationed Korea 70 and 71. Thanks for any help that you may give.
