The Board denied the veteran's claims for service connection for adenocarcinoma of the sigmoid colon and prostate cancer, finding no evidence linking these conditions to his exposure to ionizing radiation in service.
The deciding factor: The VA determined that there was insufficient evidence to support a link between the veteran's exposure to ionizing radiation during service and his current diagnoses of adenocarcinoma of the sigmoid colon and prostate.
