My husband was just diagnosed with metastatic renal carcinoma. When talking with the VA, I was told that there is a good chance that the fact he was in VN (on an engineering group) that his exposure to Agent Orange could be the cause. FYI. I have found an Appeal's Verdict regarding Phouc Vinh with regard to Agent Orange and Renal Cell Carcinoma connection. Here is the citation for anyone actively seeking VA acceptance. "Renal cell carcinoma was incurred during active service. 38 U.S.C.A. §§ 1110, 1116, 5107 (West 2002); 38 C.F.R. §§ 3.102, 3.303(d) (2002)." When dealing with the VA, it was a counselor that suggested that his condition was possibly service related. Being service related would give him a bit more money. That will help a little, but I would much rather have my favorite vet.
