Epidemiologist Christel Nielsen utilizes Swedish national health registries to study potential correlations between tattoo ink and cancer, specifically focusing on lymphoma and skin cancer. The research involves analyzing public health data and participant questionnaires to determine if the presence and characteristics of tattoos impact cancer risk.

This segment explores recent scientific findings regarding the potential link between tattoos and increased risks of lymphoma and melanoma. The hosts discuss the nuances of relative versus absolute risk, the limitations of current research, and the potential health implications of laser tattoo removal.

The segment explores the psychological motivations behind getting tattoos, highlighting their role as a marker of agency and a way for marginalized groups to reclaim their bodies.
