Tattoos May Be Linked To Cancer – Here’s Why…

“I got tattooed during a time in my life when I wasn’t fully informed about what was going into my body or what I was allowing onto my skin. Back then, it was about art, self-expression, and creative identity.”

“Today, I see it differently. Tattoos are not harmless,” Ellie Grey a book author, wrote on Facebook.
Like Grey, many people choose to get tattoos as self-expression, acts of remembrance, or transformation. But even when the meaning runs deep, tattoos can have consequences—some only now coming to light.
The Link Between Tattoos and Cancer
Many tattoo inks contain chemicals that have been classified as carcinogenic—or cancer-causing—by the International Agency for Research on Cancer.
A 2024 study by Swedish researchers found that 21 percent of participants with malignant lymphoma had tattoos compared with 17 percent of controls. The risk was highest—an 81 percent increase—among those who got their first tattoo within two years of diagnosis.
“We know that tattoo ink often contains toxic chemicals and that a significant portion of the injected ink is transported away from the skin by the immune system, which perceives it as a foreign substance,” Christel Nielsen, associate professor and lead author of the study, told The Epoch Times.
Once ink enters the dermis, the layer of skin beneath the outer layer, the immune system attempts to clear it, sending pigment particles to nearby lymph nodes and, potentially, other organs. This may disrupt immune function and trigger systemic inflammation. Over time, the persistent presence of ink in lymphatic tissue could contribute to abnormal immune activity and increase the risk of cancers such as lymphoma and skin cancer.
Are some tattoos more harmful than others?
Does Size Matter
Nielsen’s study found no clear link between the size of a tattoo and lymphoma risk.
“We did not observe an increased risk with larger tattoos, which was unexpected,” Nielsen said. “That does not mean such a link doesn’t exist—only that our study design may not have been able to detect it.”
However, Nielsen noted that a January study published in BMC Public Health on the same topic found a different pattern, suggesting that larger tattoos may indeed be associated with a higher cancer risk. The study proposed that larger tattoos might have a stronger effect due to greater overall ink exposure or prolonged exposure from tattoos acquired over time.
Tattoo risks also include infections and allergic reactions that may be difficult to treat, Dr. Bruce Brod, clinical professor of dermatology at the University of Pennsylvania Perelman School of Medicine, told the Epoch Times. Such risks may be amplified by the amount of ink used or how deeply it’s deposited—factors more likely in larger or multiple tattoos.
Does Color Matter
Another factor to consider is the color of the tattoo. In a matched analysis comparing individuals with similar characteristics, those with black or grey tattoos had a 23 percent higher risk of lymphoma. Those with both black and colored tattoos had a 21 percent higher risk compared to…
