Brief Answer: Multiple factors play after 70 yrs Detailed Answer: Hi, It would be difficult to prove a point about your occupational exposure as a reason for small cell lung cancer at the age of 84. After 70 yrs of age there are other confounding factors that play a major role in the causation of lung cancer (SCLC). Your history of COPD can hit the top for the causative factors. You can relate your occupation to COPD easily. The International Agency for Research on Cancer has identified 12 occupational exposure factors as being carcinogenic to the human lung. They are Arsenic, Beryllium, Cadmium, Aluminum production, Hexavalent chromium, Asbestos, Bis-chloromethyl ether, Crystalline silica, Nickel, Coke and coal gas fumes, Radon, and Soot. Most important is diesel exhaust and other related combustion fuels. If you can prove a point that you were exposed to Polyaromatic hydrocarbons during your occupation, it may hold a strong point and the onset of cancer was immediately after your retirement it may work for your Disability rating with the Veteran Affairs. You can write to public health/Epidemiology agency if they had recorded high incidence of lung cancers in fighter pilots and transport pilots. These occupations were not specifically mentioned in the list.
