Background and aim: Lung cancer is the leading cause of cancer incidence and mortality in Canada. Population-based screening programs using low dose computed tomography are being more widely used. Screening reduces lung cancer mortality. It also introduces potential ethical issues that need to be elucidated to inform the ethical, equitable, and effective implementation of screening programs. This aim of this research was to begin developing an understanding of what the ethical issues are and how they are being, and should be, approached in health policy.
Methods: Using empirical ethics inquiry, this research produced descriptive evidence via three independent studies: a systematic literature review and mixed methods integrative synthesis of public perspectives on screening benefits and harms, and two qualitative description studies about public and key informants’ ethical and social values on ethical issues in screening.
Results: The major finding of this research was the preponderance of ethical issues located within health and social systems and structures, including equity of screening access, stigma against people who currently smoke commercial tobacco, commercialization of tobacco, and the need for increased investment in primary prevention of lung cancer. These ethical issues reflect the social, economic, and political determinants of lung cancer and the means available to reduce the burden of lung cancer in Canada, including but not limited to screening. In health policy, there was a lack of ethical frameworks or principles currently being used to address these ethical issues and the sometimes-conflicting perspectives found between the public and key informants.
Discussion: Future empirical and normative research is needed to understand ethical and social values related to screening by populations with high lung cancer incidence and mortality, and to integrate empirical evidence with appropriate ethical theories to make recommendations for ethical, equitable, and effective population-based LDCT lung cancer screening policy in Canada. / Thesis / Candidate in Philosophy / Lung cancer is the top cause of cancer in Canada. An estimated 30,000 people were diagnosed with lung cancer and 20,700 people died from lung cancer in 2022. Screening is being more widely used to find and treat lung cancer in earlier stages. There are some ethical questions to consider, like how to ensure that screening programs are fair and effective. This research focused on understanding what the ethical issues are and how they could be solved in health policy. Perspectives on ethical issues were collected and analyzed from the public and lung cancer screening leaders. The two major ethical issues were fair access to screening and stigma against people who currently smoke commercial tobacco. There was a lack of ethical guidance to address these issues in health policy. Ethical concepts about justice and individual choice, and ethics research with key communities, may help navigate ethical issues in health policy.
