Looking to find out if I had toxic exposure in the army when I was stationed at Maison-Forte (MFT): Terminal Stationed in 1961-1962

I have been diagnosed with gastric cancer, I have had chemotherapy and radical surgery. I was stationed at MFT in 1961-1962. I am interested in finding out if I was exposed to toxins during that time. I remember the incinerators burning and climbing to the top to burn the daily crypto tapes.  Does anyone have any information? Thanks, JohnJR
