The most common sites in carcinomas were thyroid (n=60; 12.6%), breast (n=35; 7.4%), and gastrointestinal (n=18; 3.8%). The leading cancers in males were the lymphomas (n=74; 15.6%), leukemias (n=57; 12%), bone (n=21; 4.4%), and central nervous system (n=20; 4.2%), while in females, the most common cancers were the lymphomas (n=61; 12.8%), thyroid (n=40; 8.4%), breast (n=34; 7.2%), and leukemias (n=34; 7.2%).ConclusionOur findings are in concordance with studies in national and international literature and we believe that our study provides a baseline tool for future population-targeted studies.Copyright: © Saudi Medical Journal.
