Emerging research suggests a potential link between tattoos and an increased risk of certain cancers, specifically blood cancer. This connection has sparked a debate among researchers and health professionals about the health implications associated with tattooing.
Tattoos are more than mere decorations; they hold personal significance for many individuals. According to a 2023 Pew Research Center survey, about 32% of Americans have at least one tattoo, while 22% have multiple. However, the potential health risks associated with tattoos are prompting further investigation.
A study published in Applied and Environmental Microbiology in July 2024 revealed that out of 75 samples of tattoo and permanent makeup inks commonly used in the United States, 26 were contaminated with bacteria that could lead to infections. These included Staphylococcus epidermidis and Cutibacterium acnes, both of which can cause significant health issues.
Additionally, research conducted by Lund University in Sweden, published in eClinical Medicine, identified a 21% increased risk of lymphoma—a type of blood cancer—associated with tattooing. The study analyzed data from the Swedish National Cancer Register, focusing on individuals aged 20 to 60 diagnosed with lymphoma between 2007 and 2017.
This raises questions about the mechanisms through which tattoos might contribute to cancer risk and whether specific types or sizes of tattoos present greater risks. Researchers and health professionals are working to understand these connections better.
In a podcast episode hosted by Medical News Today, Maria Cohut and Yasemin Nikola Sakay discussed these findings with Milena Foerster, a researcher at the International Agency for Research on Cancer (IARC) of the World Health Organization. Foerster’s insights into the potential health risks associated with tattoos provide valuable context for this ongoing investigation.
Another contributor, Andrea Rice, shared her personal journey with tattoos and expressed her concerns about the health risks, highlighting a need for further research to understand better the limitations of current studies.
The possible link between tattoos and cancer risk, particularly lymphoma, underscores the importance of further scientific inquiry. Individuals considering tattoos should be informed about potential health concerns while researchers continue to explore the intricate relationship between tattooing and cancer. Understanding these connections is crucial for making well-informed health decisions.
