Background: Cancer is one of the leading causes of death throughout the world. The indicators of cancer by site are significant to identify the problem of cancer. The purpose of this retrospective study is to perform the incidence of all cancers both in males and females over the ten years in Nepal. Methods: The data collected from all the seven hospital based cancer registries of Nepal have taken for the study. This retrospective study has presented the number of cases, frequencies, and crude incidence of all cancers by sex and site. Results: A total of 55,931 cancer cases with known age were registered throughout the hospital based seven cancer registries of Nepal from 2003 to 2012. Throughout the ten years, Lung (incl. trachea and bronchus) cancer (19.08%) was the major cancer in males followed by stomach cancer (7.86%) and Pharynx cancer (5.4%). Similarly, Cervix cancer (21.9%) was the most common cancer in females followed by breast (15.48%) and Lung (incl. trachea and bronchus) cancer (10.47%) over the ten years. This retrospective study presented the distribution of the cancer site over the ten years in Nepal. Conclusion: This retrospective study showed that lung cancer is the major cancer in male while in female cervix uteri is the most common cancer ranging from 2003 to 2012.

Background: Cancer incidence data are vital for cancer control planning in any nation. This retrospective study was conducted to compare the cancer incidence of all sites between the first cancer registry report and the most recent example in Nepal. Material and Methods: The cases in the first (2003) and latest (2013) national cancer registry reports, accumulated by all the hospital based cancer registries in Nepal were taken for the research. The frequencies, crude incidences and age specific incidences (per 100,000) of the five major cancers were calculated for both males and females. Result: The most common cancer type for males in both years 2003 and 2013 was lung. Stomach was the third most common cancer in 2003 while it was the second in 2013. Similarly, the first four major cancers (cervix, breast, lung and ovary) did not change between 2003 and 2013 in females. The total cancer incidence rate increased from 12.8 in 2003 to 30.4 per 100,000 in 2013 for males and from 15.1 to 33.3 in females. Conclusion: The most common cancers in males in 2003 and 2013 were in the bronchus and lung. Similarly, the most common cancer in females was cervix at both time points. The cancer incidence rate in females was higher than in males both in 2003 and 2013.
