New Delhi: Tattooing, so popular among the young, can increase the risk of skin cancer, say doctors.
According to doctors, inks used in tattoos may contain toxic elements, which can cause skin cancer, especially blue ink, the age-old colour of choice for tattoo artists, which has cobalt and aluminum.
Red ink may have mercurial sulfide and certain coloured inks often contain lead, cadmium, chromium, nickel, titanium and other heavy metals.
