Explore dormancy phenomena in cancer progression through this comprehensive 58-minute lecture by Anna Kraut from the Hausdorff Center for Mathematics. Gain insights into how dormancy mechanisms contribute to therapy resistance in cancer cells and delayed metastatic relapses. Examine mathematical population models used to study dormancy in various contexts, including seed banks and pathogen behavior. Discover how cancer cells can enter a dormant state to avoid detection during treatment and later reactivate. Learn about tumor metastasis and the role of dormant cell states in cancer progression. Delve into topics such as tumor immune equilibrium, density-dependent dormancy, and population growth dynamics. Engage with open questions and potential future research directions in this field. Enhance your understanding of cancer biology, mathematical modeling, and the challenges in developing effective cancer treatments.
