Other studies on whether or not the inks can cause cancer have been inconclusive, but the original study researchers admit there’s much more investigation to be done in order to declare tattoos definitively safe or unsafe.

“In future experiments, we will also look into the pigment and heavy metal burden of other, more distant internal organs and tissues in order to track any possible biodistribution of tattoo ink ingredients throughout the body,” write the authors.
