Is it possible to have a tatoo done over a keloid scar? - put tatoo in keloid is safe

I have a keloid scar on his chest a few inches below the collarbone. I am very aware, because it attracts many eyes. I can not wear clothing under the neck because of it. So, now I want to put a tattoo of him in camouflage and make it more presentable. Is it possible tattoo or keloids makes me terribly? Are there any health effects?
