Does anyone know anything about these? My boyfriend has alot of them he has for years. They're just sitting there...being cysts lol but the question he's asking me is...can he get a tattoo over them? He wants to get a tattoo on his side but he's worried because there is one cyst in the tattoo area.

I tried googling it (and of course he's going to get a Dr.s opinion) but in the meantime any thoughts?
