Dark ring around areola??

Ok so my areolas themselves don't reallyyy seem darker, but like the outer edge looks darker. Like there's just a dark ring around the areola, it almost looks like the edge of it is smudged a little. I've never noticed this before. Is this something to worry about since its new? I'm afraid to google it it'll probably say breast cancer or something and I'll freak myself out, so can anyone help..
