To All,
If you haven't searched the VA site in the Board of Appeals section, here is the link to the VA Claims section.
http://www.bva.va.gov/
I just tried searching for all of you, but the site is closed at the moment and will be up at a later date. Once you open the link given, on the left hand side, look for- Search Decisions-.
Once you get there, you can searcch by year. Type in the words needed to search Colon Cancer/Agent Orange and you will see the claims filed in that year. To simplify your search, scroll down to the bottom of each claim and see the results, be it - Denied or Granted. Read some of the claims that were denied and find out why. If you do find some that were Granted, keep those and read exactly what needed to be done in order for the Veteran or the Spouse to be granted Service connection to Agent Orange.
Also, although the VA states that many cancers are not on the presumed list, they DO look at each case and decided according to the evidence given to them by the Veteran.
It is a rare case that wins when the Veteran or Spouse put in a claim on their own. It usually takes the help of a Veteran's Service Officer (VSO) that is certified by the VA who works for the different Military Organizations in your area such as the Vietnam Veterans of America, VFW, DAV, or American Legion,etc.
Don't give up, it can be a long battle. Unfortunately, the VA is under staffed and they have not only the real claims to look at, but those that state that they served and were never in the Military to start with. The VA has to weed out those claims as well.
I hope that is of some help.
My Best to Everyone Here
