A brand new examine suggests a hyperlink between tattoos and an elevated threat of creating malignant lymphoma, a blood most cancers that impacts the lymphatic system.
The declare comes from analysis printed in Could within the journal eClinicalMedicine, which discovered that having a tattoo was related to 21% greater odds of a lymphoma analysis.
Tattoos have grown in recognition in recent times—in the US, 23% of individuals stated that they had a tattoo in 2010, in comparison with 32% in 2023—and researchers have turn out to be more and more occupied with investigating how they have an effect on the physique.
“The examine means that tattoos could also be a threat issue for malignant lymphoma that’s actionable from a public well being perspective,” the authors concluded.

Some earlier proof has steered a free connection between tattoos and most cancers.
For instance, the Worldwide Company for Analysis on Most cancers has categorized some chemical compounds present in tattoo ink, reminiscent of main fragrant amines, as carcinogenic or probably carcinogenic, although principally solely when ingested, inhaled, or utilized on high of the pores and skin.
Research have additionally proven that pigment from tattoos finally ends up being filtered by and saved within the lymph nodes, the place some lymphoma instances start.
It’s in opposition to this backdrop that Nielsen and her colleagues sought to know extra in regards to the long-term results of tattoo ink.
They used the Swedish Nationwide Most cancers Register, a nationwide well being database, to determine each case of malignant lymphoma recognized in about 12,000 individuals aged 20 to 60 between 2007 and 2017. Then, they in contrast the info to solutions from a questionnaire they distributed in 2021, which requested individuals if that they had tattoos and, in that case, what number of and the way massive an space the ink lined.
In complete, about 20% of individuals had tattoos. Researchers found that having a tattoo was related to about 21% elevated odds of lymphoma, with the scale of the tattoo having no affect on an individual’s threat.
Lymphoma was highest in individuals who had gotten a tattoo lower than two years earlier than their analysis. That threat decreased till 11 years between tattooing and analysis, when it rose once more.
Lymphoma impacts the a part of the physique that helps your immune system combat off infections. There are two sorts: non-Hodgkin lymphoma, which accounts for about 4% of most cancers diagnoses within the U.S., and Hodgkin lymphoma, which is much more unusual.
“It is very important remember the fact that lymphoma is a really uncommon illness,” the examine’s lead writer, Christel Nielsen, PhD, affiliate professor within the division of occupational and environmental medication at Lund College in Sweden, informed Well being. “The rise pertains to a baseline threat that could be very low.”
There is no motive to panic when you have a tattoo or are contemplating getting one, stated consultants interviewed.
Some environmental elements do certainly increase the probabilities of most cancers. Within the case of lymphoma, a weakened immune system and publicity to chemical compounds reminiscent of benzene and a few herbicides are recognized threat elements.
Nonetheless, Marc Hoffmann, MD, director of the lymphoma program within the division of hematologic malignancies and mobile therapeutics on the College of Kansas Most cancers Heart, informed Well being that you simply want vital evidentiary assist to find out {that a} explicit environmental publicity triggers cancerous cells.
The hyperlinks between most cancers and smoking or nuclear radiation publicity, for instance, “are dramatic and simple,” he stated. However that clear connection has not been established for tattoos, he added.
In truth, two earlier research that investigated whether or not there is a hyperlink between tattoos and lymphoma didn’t discover one.
Catherine Diefenbach, MD, a hematologist–oncologist at NYU Langone in New York, informed Well being that she’s even skeptical about the latest examine’s conclusions.
The discovering that there was a heightened threat of lymphoma inside two years of getting a tattoo after which once more after 11 years does not add up, she stated.
“The opposite factor that doesn’t make sense is that if it is a toxin that will get put into the physique by ink, there isn’t an affiliation between the scale of the tattoo and most cancers threat,” she stated. The “examine does increase questions, however the majority of sufferers with tattoos don’t develop lymphoma.”
