A recent study suggests that tattoos may increase the risk of developing melanoma, a dangerous form of skin cancer. Conducted by a team of researchers, including myself, the study found that people with tattoos had a 29% higher risk of melanoma. However, tattoos did not appear to affect the likelihood of developing squamous cell carcinoma, another type of skin cancer linked to UV exposure.
Melanoma, which often develops due to ultraviolet (UV) exposure, is a far more serious cancer than squamous cell carcinoma. Despite the popularity of tattoos, their impact on health is not well understood. Many people, particularly in Sweden, where one in three adults is tattooed, choose body art for self-expression. Yet, there is limited scientific research on whether tattoos affect health over time.
Our study used a case-control approach to investigate the relationship between tattoos and skin cancer. We examined health data from Sweden’s National Cancer Register, focusing on people aged 20 to 60 diagnosed with melanoma or squamous cell carcinoma between 2014 and 2017. After gathering information from over 11,000 participants, we found that those with tattoos were at a higher risk of melanoma, especially those who had tattoos for more than ten years.
However, the study’s design has limitations. Long-term research would be necessary to draw definitive conclusions. Tattoos and skin cancer both develop slowly, making it challenging to track patterns over many years. Moreover, health records often do not specify whether someone is tattooed, complicating the research further.
While the study’s findings raise awareness, there is no need for panic. People with tattoos should continue to protect their skin from UV radiation. Regular use of sunscreen, avoiding excessive tanning, and checking for skin changes are key steps in maintaining skin health.
