werickso49,
Of all the dioxins, TDCC (which stands for 2,3,7,8-tetrachlorodibenzo-p-dioxin) is one of the most toxic, and it was found in Agent Orange. Some vets and their supporters are working at the political and scientific levels with the evidence that continues to accumulate, showing that Agent Orange and its contaminants were primary causes of bone marrow failure, while other vets seek full medical evaluations from doctors who might be able to give them written statements about the connections between their disease and their exposures, which the vets can then use during the appeal process.
I suggest that you read and post in our
MDS, Agent Orange and the VA forum thread.
