Tattoos have become a mainstream form of self-expression, with 32% of Americans now sporting at least one, and 22% adorned with multiple tattoos, according to a 2023 Pew Research Center survey. For many, tattoos are not only art but also a way to honor personal milestones or symbolize emotional resilience. 

However, a rising body of research is raising questions about the long-term health impacts of tattooing, including potential links to cancer and infection risks.

A recent study published in Applied and Environmental Microbiology in July 2024 uncovered alarming findings: out of 75 tattoo inks and permanent makeup products commonly used in the U.S., 26 were contaminated with bacteria that could lead to infections. Among the contaminants were Staphylococcus epidermidis, which can result in serious infections, and Cutibacterium acnes, which is associated with acne.

An even more unsettling discovery comes from Lund University in Sweden. In a study published in eClinical Medicine, researchers reported a 21% increased risk of lymphoma—a type of blood cancer—among tattooed individuals. Using data from Sweden’s National Cancer Register, the study focused on adults aged 20 to 60 diagnosed with lymphoma between 2007 and 2017. While this association doesn’t imply causation, it raises important questions: What might be contributing to this increased risk? Could certain tattoo pigments or procedures carry higher health risks?

A recent discussion delved into these findings with Dr. Milena Foerster, a tattoo and cancer research expert at the International Agency for Research on Cancer (IARC) under the World Health Organization. Foerster shared insights into why tattoos may pose cancer risks, potential mechanisms at play, and considerations for those considering tattooing.

The conversation also featured personal experiences from individuals who shared their journey with tattoos and the health concerns they have encountered. One participant highlighted the limitations of current research, noting that while some studies indicate potential risks, more comprehensive investigations are necessary to understand the scope of these health implications fully.

For individuals with or considering tattoos, experts recommend using certified inks, researching reputable tattoo studios with stringent hygiene practices, and staying informed about ongoing research on tattoo safety. As studies continue to evolve, being proactive and informed remains the best approach to balancing self-expression with health considerations.
