Mumbai, Jan 2: From Bollywood celebrities flaunting elaborate mandala sleeves to youngsters sporting minimalist lotus designs, tattoos have become a mainstream form of self-expression across India. Tattoo studios in metros like Bengaluru, Delhi and Mumbai are witnessing a steady surge, with people from all age groups embracing body art as a way to tell personal stories.
However, alongside this growing trend, new scientific studies are raising concerns about possible long-term health risks linked to tattoo ink, including an increased risk of certain cancers. While experts do not call for abandoning tattoos altogether, they urge people to be informed and cautious.
Once associated mainly with rebels and rockstars, tattoos are now common among college students, corporate professionals and even older adults opting for subtle, meaningful designs. Social media and celebrity influence have played a major role in normalising tattoos, contributing to the rapid growth of India’s tattoo industry.
But medical researchers point out that tattoo ink particles remain in the body permanently, prompting questions about their long-term impact on health.
A major study from Denmark has brought renewed attention to the issue. Researchers analysed data from nearly 6,000 twins, a group considered ideal for such studies because of shared genetics and environment. The findings, published in BMC Public Health, showed that tattooed individuals had a 62 per cent higher risk of being diagnosed with cancer compared to those without tattoos.
The risk appeared higher for skin cancer, with tattooed participants being 1.6 times more likely to develop the disease. The study also found that larger tattoos—roughly the size of a palm or bigger—were associated with significantly higher risks, including 2.4 times higher skin cancer risk and 2.7 times higher risk of lymphoma.
Researchers accounted for factors such as smoking, obesity and sun exposure, strengthening the credibility of the findings.
Lymphoma, a cancer affecting the lymphatic system, has emerged as a key concern. Scientists explain that tattoo ink breaks down into microscopic nanoparticles that can travel from the skin to lymph nodes, where they may cause chronic immune reactions over several years.
Earlier Swedish research had also indicated a 21 per cent increased risk of lymphoma among tattooed individuals, regardless of the number of tattoos. The size of the tattoo appeared more influential than the count.
The link between tattoos and skin cancer remains complex. Some European studies suggest a higher risk of melanoma among tattooed individuals, possibly because ink particles interfere with skin cells or mask early warning signs. However, a study from the US reported lower melanoma rates among people with multiple tattoos, attributing this to reduced sun exposure or better skin awareness.
Despite these mixed results, Danish data indicated a higher likelihood of other skin cancers among tattooed individuals.
Tattoo inks contain a mixture of chemicals, including heavy metals such as nickel and chromium, and substances like carbon black. Some pigments, particularly certain red inks, have already been banned in parts of Europe due to carcinogenic properties.
In India, regulation of tattoo inks remains limited, and the use of low-quality or imported pigments without proper certification is a concern. Health experts warn that unregulated inks and unhygienic tattooing practices significantly increase health risks.
Medical professionals stress that tattoos do not pose an immediate danger, but long-term risks cannot be ignored. They recommend choosing reputed studios, avoiding large tattoos if possible, and ensuring the use of certified inks and sterile equipment. Regular skin check-ups and monitoring tattooed areas for changes are also advised.
As research continues and safer inks and stricter regulations are developed, experts believe awareness is key. Tattoos may remain a powerful form of self-expression—but getting inked responsibly could make the difference between art and a health hazard.
