New Study Suggests Tattoos May Increase Cancer Risk

FINE INK STUDIOS, KISSIMMEE, FL

A recent study conducted by researchers at the University of Southern Denmark and the University of Helsinki suggests that individuals with tattoos covering a large portion of their  body may have a significantly higher risk of developing skin cancer and lymphoma. The findings, published in March 2025, indicate that those with tattoos larger than the size of a palm are nearly four times more likely to be diagnosed with skin cancer compared to those without tattoos (UPI). 

The study analyzed health data from thousands of individuals, focusing on the effects of tattoo ink on the body. Researchers highlighted the presence of certain harmful chemicals in tattoo inks, such as heavy metals (lead, cadmium, mercury) and polycyclic aromatic hydrocarbons (PAHs)—substances that have been classified as carcinogens by the World Health Organization (WHO). These chemicals, commonly found in some industrial processes, may accumulate in the body over time, raising concerns about long-term exposure risks. 

Laszlo Barr, a tattoo artist at Fine Ink Studio in Kissimmee, Florida, shared his thoughts on the study's findings. "Safety is our highest priority. We take great care in sourcing our inks exclusively from reputable manufacturers who rigorously adhere to FDA regulations. Nonetheless, it is essential to acknowledge a substantial knowledge gap concerning the long-term effects of exposure to tattoo ink. Our commitment to quality and transparency underscores the importance of ongoing research in this field," Barr remarked, emphasizing the industry's cautious approach to safety. 

Industry and Public Reactions 

The study has raised concerns among both tattoo enthusiasts and health professionals. Some dermatologists recommend that individuals with tattoos monitor their skin for unusual changes, such as persistent redness, irritation, or new growth. Meanwhile, professionals in the tattoo industry are calling for stricter regulations on ink ingredients to ensure clients' safety. 

However, the study's authors caution that more research is needed to establish a definitive link between tattoos and cancer. They stress the importance of further investigations into different tattoo ink types and their long-term effects on human health (American Cancer Society). 

As tattooing continues to be a popular form of self-expression, this study highlights the need for continued research and safety awareness within the industry.
