Tattoos Associated With Increased Lymphoma Risk, and Size Doesn’t Matter: Study
Tattoos Increase Cancer Risk by 21 Percent
Tattoos have grown increasingly popular as a means of self-expression. Around 32 percent of Americans have at least one tattoo, and an estimated 22 percent have multiple.
The study analyzed data from nearly 12,000 people aged 20 to 60, matched with a control group of the same age and sex without lymphoma. Participants completed questionnaires about lifestyle factors, including tattoos. Researchers found that those with tattoos were more likely to develop malignant lymphoma compared to those without tattoos.
People with tattoos had a 21 percent higher risk of developing any type of lymphoma after adjusting for other factors.
Size Doesn’t Seem to Matter
A larger total tattoo size did not seem to increase the risk further.
“We do not yet know why this was the case,” Christel Nielsen, who led the study, said in a press release. ”One can only speculate that a tattoo, regardless of size, triggers a low-grade inflammation in the body, which in turn can trigger cancer.”
The picture is thus more complex than initially thought, she noted.
The research is the first to investigate tattoos as a risk factor for cancer in the lymphatic system, Ms. Nielsen told The Epoch Times. Further studies investigating potential links between tattoos and other cancer types are underway.
Growing Evidence for Tattoo-Related Cancer Risks
“We know that tattoo ink often contains hazardous chemicals and that it is deposited in lymph nodes,” Ms. Nielsen told The Epoch Times. The immune system always “attempts to clean out the ink particles that it perceives as something foreign that should not be there,” she added.
The findings showed that compared to never receiving a tattoo, getting a first tattoo before age 20 was associated with elevated myeloid neoplasm risk, while receiving a first tattoo at age 20 or older was linked to higher lymphoma risk. However, the authors cautioned that these estimates were “imprecise.”
