Fort Bragg soldier fighting lung cancer says medical mistake by military doctor will cost him his life

PINEHURST, N.C. --

A Fort Bragg Green Beret soldier who fought for our country is now fighting cancer and the government.
Sgt. First Class Richard Stayskal has stage four lung cancer and it's a diagnosis he says should have been caught earlier but was missed by military doctors.
"I went six months without being treated, six months of nothing being done to me a tumor just growing," he told ABC11.
