Experts are advising people to be cautious when choosing tattoo ink colors. While tattoos remain popular and do not seem to be going out of fashion, research shows that some inks may carry health risks.
People get tattoos in many ways. Some cover large parts of their bodies with ink, while others prefer small, scattered designs. Regardless of the size or style, a recent scientific study warns that certain inks could increase the chance of long-term health problems.
A study published last year by Sweden’s Lund University found that tattoos may raise the risk of lymphoma, a type of blood cancer. The study showed that tattooed individuals have a 21 percent higher risk of developing lymphoma compared to those without tattoos. Although lymphoma is rare, any tattoo ink color could pose some risk, with certain colors being more dangerous.
The researchers explained that the body sees tattoo ink as a foreign substance. The immune system tries to remove this ink by moving it to the lymph nodes. This reaction may contribute to health complications.
According to the NHS, lymphoma affects about 14,000 people in the UK each year. It starts in white blood cells and can spread to organs that fight infection. Though lymphoma is uncommon, the link to tattoos is causing concern.
Further studies have focused on the effects of specific ink colors. The group Non Toxic Revolution found that red tattoo ink causes the most skin reactions. This is because red pigments often contain metals like cadmium, mercury, or iron oxide.
Tattoo aftercare is also very important. Treating a new tattoo like an open wound helps prevent rashes, pain, and infections. Ignoring proper care can lead to short-term problems.
However, the long-term risks are a bigger concern. A study from Duke University School of Medicine reported several cases where tumors developed within tattoos. It found that red ink was involved in nearly 37 percent of these tumor cases.
To reduce risks, experts suggest choosing black ink, which appears safer based on current research. Some countries, including the UK, have banned certain tattoo inks believed to cause cancer. Manufacturers have been given time to create safer ink formulas.
