SCIENTISTS have uncovered a link between your favourite ink and cancer.
Researchers from the European Synchrotron Radiation Facility in France say the chemicals in tattoo ink travel in the blood stream and accumulate in the lymph nodes, obstructing their ability to fight infections.
It's not the first time tattoos have been linked to cancer.
Titanium dioxide, a chemical commonly used to create white ink, is known to increase the risk of the disease, as well as causing delayed healing in the wound.
"When someone wants to get a tattoo, they are often very careful in choosing a parlour where they use sterile needles that haven't been used previously," said study author Hiram Castillo.
"No one checks the chemical composition of the colours, but our study shows that maybe they should."
