Multiple tattoos linked to lower melanoma risk, but one tattoo tied to higher risk; experts urge sun protection.
A study in the Journal of the National Cancer Institute links multiple tattoos to a lower risk of melanoma, finding that four or more tattoo sessions were associated with a 56% lower risk, and three or more large tattoos with a 74% lower risk, compared to no tattoos.
Getting a first tattoo before age 20 was linked to a 26% lower melanoma risk.
However, having just one tattoo was tied to a 53% higher risk.
Researchers suggest possible explanations include better sun safety habits, ink acting as a UV barrier, or immune system responses, but stress the findings are not conclusive.
Experts emphasize that sunscreen and sun protection remain essential for all, as UV exposure can degrade tattoo ink and potentially harm skin.
Further research is needed to understand the connection.
