Tattoos could give you cancer, new research suggests. It’s the first time extensive research has concluded it. The ESRF says the chemicals in tattoo ink travel in the bloodstream and accumulate in the lymph nodes, which may cause them to become swollen and therefore hinder their ability to fight infections.
Controversial chemical titanium dioxide, which is added to tattoo ink to create certain colours, even dyes lymph nodes, and has previously been linked to cancer, itching and delayed healing. Study author Hiram Castillo from the European Synchrotron Radiation Facility in France, said: “When someone wants to get a tattoo, they are often very careful in choosing a parlor where they use sterile needles that haven’t been used previously. No one checks the chemical composition of the colors, but our study shows that maybe they should.”
