Hey my name is Rob! To tell you a little about my case! In 1997 , I was diagnosed with large B cell lymphoma can in my chest above my heart! Which requred 2 yrs of aggressive chemotherapy and 1 yr of radiation. Which also , I was medically retired from military. In 2015, i had an heart attack. The cardiologist put in my nexis letter heart attack was probably secondary to chemorherapy and radiation. My doctor put in his closing that chemo was believed to be the causative agents. Im stressing out. How do anyone think this will fly with VA. I never knew nothing about this VA wording ! Probably is a very strong word in the dictionary. Rock let me know your case turned out! My email address rcktkay@ gmail.com . Should i try to get my VA doctor to write me a nexus letter? Help! Help ! HELP
