Understanding the link between tattoos and lymphoma risk


Recent research from Lund University in Sweden has sparked a conversation about the health implications of tattoos, particularly their potential connection to an increased risk of lymphoma. This study, which delved into the Swedish National Cancer Register, has identified a 21% heightened risk of lymphoma for individuals with tattoos compared to those without.

Study findings and implications

  • Tattoo ink contains carcinogens that can travel to and accumulate in lymph nodes.
  • The research team found that the size of the tattoo did not significantly affect lymphoma risk.
  • There was an 81% higher risk of lymphoma in the first two years after getting a tattoo, which then varied over time.
  • The study controlled for confounding factors such as socioeconomic status and lifestyle choices.

Research methodology

The study focused on individuals aged 20-60 diagnosed with lymphoma between 2007 and 2017. Out of the 1,398 people with lymphoma and 4,193 controls, researchers discovered a correlation between tattoo presence and an increased incidence of lymphoma.

The study also touches on the risks associated with needle use in tattooing, such as the transmission of hepatitis C, which is linked to an increased risk of non-Hodgkin lymphoma.

Expert insights

Experts not involved in the study, such as Wael Harb, MD, and Rachel Orritt, PhD, emphasize the need for further research to isolate the effects of tattoos from lifestyle factors that may also contribute to cancer risk. They also remind the public that proven steps to reduce cancer risk include not smoking, maintaining a healthy diet, and moderating alcohol consumption.

Public health considerations

With the rising popularity of tattoos, it’s crucial to understand the long-term health effects of ink exposure. While lymphoma remains a rare disease, the study’s lead author, Christel Nielsen, PhD, advises tattooed individuals to be vigilant about potential health issues and to seek medical care for any concerning symptoms.

Future research by Nielsen’s team will explore the relationship between tattoos and other health conditions, including skin cancers and autoimmune diseases. As tattoos continue to be a popular form of self-expression, it is essential to stay informed about the potential health risks and to follow any new developments in this field of research.
