In a nutshell:
Danish twin study found people with large tattoos (bigger than palm-sized) had 2.73 times higher rate of developing lymphoma and 2.37 times higher rate of skin cancer
Tattoo ink particles migrate through the body to lymph nodes and other organs, potentially causing chronic inflammation that may increase cancer risk
Time between getting a tattoo and cancer diagnosis averaged 8 years for lymphoma and 14 years for skin cancer, suggesting a substantial latency period
