I read that tattoo ink may contain Polycyclic Aromatic Hydrocarbons. Does exposure to these chemicals guarantee cancer? Can the body rid itself these?

Tattoos and Cancer. Studies show Polycyclic Aromatic Hydrocarbons (PAH) exist in the atmosphere and are established human carcinogens. They are also concentrated in black tattoo inks. Tattoos introduce substances like this for life and the skin cannot totally rid itself of the PAH. However, exposure to PAH does not guarantee cancer. Melanoma and other skin cancers are found in tattoos but tattoo link not proven. .
