Tattoos have come a long way—from rebellious statements to mainstream body art. But could those beautiful ink designs come with an unexpected health risk?
A recent study from the University of Southern Denmark has raised some eyebrows. Researchers there explored a possible link between tattoo ink exposure and cancer, specifically skin cancers and lymphomas.
The Study: Tattoos vs. Cancer Risk

This research, titled “Tattoo ink exposure looks at the risks of lymphoma and skin cancers – a Danish study of twins,” was based on data from the Danish Twin Tattoo Cohort. That’s over 5,900 twins, making it one of the most unique and controlled ways to study how tattoos might impact cancer risk.
By comparing twins—where one has tattoos and the other doesn’t—the study found that the tattooed twin had a 1.62 times higher risk of developing skin cancer. Now, before you go cancelling that tattoo appointment, let’s dig into what this really means.
Why Could Tattoos Pose a Risk?

According to Henrik Frederiksen, a hematology consultant at Odense University Hospital, tattoo ink doesn’t just stay on your skin. The ink particles travel to your lymph nodes, where they might trigger the immune system to respond as if it’s dealing with an invader.
Over time, this could cause chronic inflammation, which has been linked to various forms of cancer. However, it’s still unclear whether certain ink colors or larger tattoos pose a bigger risk.

“We do not yet know whether this persistent strain could weaken the lymph nodes or have other health consequences,” Frederiksen said.
Should You Be Worried? Not Really.
Study co-author Signe Clemmensen told New Scientist that while the findings are interesting, there’s no need to panic.
“It’s not something people should be overly concerned about yet.”
That sentiment is echoed by Rachel Orritt from Cancer Research UK, who emphasized there’s still not enough evidence to say tattoos cause cancer.
What This Means for Tattoo Lovers
If you’re planning to get inked, there’s no need to cancel your appointment. Just make sure you’re:
- Choosing a reputable tattoo artist
- Using approved ink pigments
- Following proper aftercare instructions
As more studies emerge, we’ll understand better whether tattoos are just art—or something more.
