Malignancies represent a significant proportion of health problems in the working population. This study attempts to determine the frequency of disabling malignancies in air force personnel in a period of 11 years (during 1371-1382). Materials and methods: In a retrospective, cross-sectional design a descriptive-analytical study was conducted on all military and nonmilitary (office workers) personnel who had retired for medical reasons with a diagnosis of cancer during 1371-1382. The SPSS software was used for data analysis. Results: Among 1931 individuals who had an early retirement foe medical reasons, 160 (8.3%) had cancer. Average age was 41.2±5.9 years. Average lost service years were 7.5±5.6 years. The malignancies of the nervous system were the most common type (46 cases, 28.7%), including brain tumors (36 cases, 22.5%), followed by gastrointestinal cancers (36 cases, 24.5%). There was a significant relation between different service and the type of cancer. Conclusion: The prevailing disabling cancers were observed in the nervous system and the gastrointestinal tract this is similar to other studies. According to our findings cancers do not seem to be a significant etiology for disability. The higher frequency of gastrointestinal cancers in our study may be related to a certain diet or an unhealthy life style factors that are easily amenable to elimination by proper education. M3 ER -
