The analysis aims to support decision-making related to investments in cancer prevention and new treatments, by highlighting the economic burden associated with five types of cancer.</p><p><strong>Methods: </strong>The human capital approach was used to estimate productivity losses from premature mortality due to liver, lung, breast, bladder, and cervical cancer in Egypt in 2019 by calculating years of life lost (YLL), years of productive life lost (YPLL), and present value of future lost productivity (PVFLP). Mortality data were sourced from the World Health Organization (WHO), while life expectancy, retirement age, gross domestic product (GDP) per capita, and labor force participation rates were obtained from the World Bank. Income data, such as annual earnings and minimum wage were sourced from the Wage Indicator database. Deterministic sensitivity analysis (DSA) assessed the sensitivity of results to input variations.</p><p><strong>Results: </strong>In 2019, Egypt had a total of 45,114 deaths, from liver, lung, breast, cervical, and bladder cancers, resulting in a productivity loss of $430,086,636. Liver cancer led to the most male deaths (17,745) and breast cancer to the most female deaths (6,754), with PVFLP of $232,663,468 and $130,745,592, respectively. The five cancers resulted in 551,336 YLL and 235,415 YPLL in Egypt. The total PVFLP was estimated at $217,224,178 for females and $212,862,458 for males, with a total PVFLP/death of $9,533. The DSA showed that the PVFLP was most sensitive to changes in the retirement age.</p><p><strong>Conclusion: </strong>In conclusion, there is a substantial economic burden relating to premature cancer mortality in Egypt, highlighting that policies and treatment advances to decrease cancer are working, however, there is need for continuous prioritization of awareness programs, cancer screening and treatment advancements.</p>","PeriodicalId":16229,"journal":{"name":"Journal of Medical Economics","volume":" ","pages":"36-43"},"PeriodicalIF":2.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142769614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
