Cancer is one of life's hardest blows, Im sorry to hear of your misfortune. Take a minute and think about it, the military will not take anyone with pre existing conditions. They are in need of people that are ready to be deployed not the sick needing treatment. Places like Iraq and Afghanistan are not set up to monitor people like you. People who are injured or become sick with cancer are given a medical discharge out the Army. To sue the military wont do you any good it will just be thrown out of court because they have done nothing wrong. As far as SSI, if you feel you were well enough to join the military then why are you not well enough to join the American work force. There are other ways to serve your country then the military, like working hard! SSI in a case like this is nothing more then feeling sorry for yourself looking for a free hand out. I speak from experience as an Army 11 bravo kicked out the Army after a near death accident that has left me with serious pain for the rest of my life. I don't blame the Army, It's just another card dealt to me that makes me a stronger person inside, so like millions of other Americans and Vets pick your head up, be strong and drive on.
