Is it okay to get a tattoo in the same spot of an epidermoid cyst removal ? (Photo)

I have what I believe is a epidermoid cyst. I've had it for ad long as I could remember . I am now 17 and plan on getting it removed when Im 18 for cosmetic purposes . After the surgery I'm sure there will still be a small scar still so im wondering if I can get a tattoo to cover it up after surgery ?
