A recent study conducted by Lund University in Sweden through an analysis of the Swedish National Cancer Register found that 20% of people with lymphoma had a tattoo. The risk was 81% higher for people with tattoos to contract lymphoma in the first two years of getting the tattoo. What is Actually Causing The Increased Risk?Overall, what the study had found was that the risk of contracting lymphoma seemed to be connected to the time they had gotten the tattoo. 3 years after their initial tattooing, this risk dropped and then increased again by 19% after 11 years. The size of the tattoo appeared to have no impact on the risk, interestingly enough. However, the study could not isolate the specific factors that could be causing lymphoma. According to the authors, the study “adjusted for several lifestyle factors like smoking or eocioeconomic status”, however tattoos in themselves appeared to be the risk factor.From what is already known on tattoo ink materials, tattoos can contain carcinogens that enter the body and end up inside the lymph nodes themselves. However, researchers haven’t been able to specifically tie this phenomenon to an increased cancer risk. Part of this is attributed to the fact that there are a lot of different possible ingredients in tattoo ink, which can make understanding the side-effects quite difficult.What Do The Study’s Authors Recommend For TattooistsDespite the findings, the study’s authors did assert that tattoo popularity has increased since the early 2000s and that most of the research team had tattoos. However, they believe that the health impact haven’t been effectively studied.They believe that the findings do not indicate a need to worry, however, people should still be aware of the effect that getting a tattoo has on their body and physical health. According to Nielsen, the study’s lead author, “It is important to keep in mind that lymphoma is a very rare disease, and that the 21% increase relates to a baseline risk that is very low. However, I would like to highlight that tattooed individuals should be aware that tattoos might have adverse health effects, and that you should seek medical care if you experience any symptoms that you think may be tattoo-related.
