A recent study from Sweden suggests that individuals with tattoos may have a 21% higher risk of developing lymphoma, a type of blood cancer. The research, led by Christel Nielsen from Lund University, emphasizes the importance of further investigation to confirm these findings at the group level. The study involved 11,905 participants who completed a lifestyle questionnaire to identify tattooed individuals. Results indicate that the risk of lymphoma may be more pronounced for diffuse large B-cell lymphoma and follicular lymphoma. Despite initial hypotheses about tattoo size impacting risk, researchers found that it was not a significant factor. The study theorizes that tattoos may trigger low-grade inflammation in the body, potentially leading to cancer. Nielsen's team highlights the need for oversight of tattoo ink composition due to its impact on the immune system. Future research aims to explore connections between tattoos and other cancers and inflammatory diseases.
