The scientist’s investigation covers issues in Internal medicine, Breast cancer, Cohort, Cancer and Cohort study. His Internal medicine research incorporates themes from Endocrinology and Oncology. David B. Thomas interconnects Gynecology and Family medicine in the investigation of issues within Breast cancer.

His research in Gynecology intersects with topics in Odds ratio, Mammography, Disease and Obstetrics. His study in Cohort is interdisciplinary in nature, drawing from both Proportional hazards model, Surgery, Relative risk and Cumulative Exposure. His Cohort study research incorporates elements of Epidemiology, Gerontology, Environmental health, Prospective cohort study and Lung cancer.

Between 2006 and 2021, his most popular works were:
