Carcinoma From Agent Orange?

I am a retired vet and was in various places in Viet Nam in 1966 and 1972. I had throat cancer and had an operation in 1998 and they did find carcinoma of the larynx. I did not apply to the VA for any type of compensation at that time. I am currently applying to the VA for compensation. I did receive radiation treatments which I partially paid for at that time. I was wondering if anyone else has had this type of cancer and if they have applied to the VA about it and if they had received any type of positive action from the VA. I am more interested in finding out if Agent Orange had anything to do with me getting this cancer. Any response to me would be appreciated. My VA appointment is 9/2/05.
