Mrs Proffer,I am sorry for your loss.
I served A/6/44 from June 1971 until January of 1972 and between ionizing radiation and herbicide use to control vegetation many of us suffer many types of cancers. I repaired the radars so I was exposed to all of whatever was used. I filed a claim in 2013 and have been fighting many forms of cancer and have been working with the VA to try to win some help but have not as yet won. If you want to talk to your local VA rep about your husbands service they will help you as much as they can most are good folks trying to help.Look them up under VA.org to find the closest one.
