Keloid is a scar that rises above the skin after an injury.
It occurs in all people with different skin colours although people with darker skins are most likely to develop.
Most keloids occur as a result of minor accident (burns, insect bites,piercings and tattoos) although some are hereditary.
You can go ahead and marry the person but its a 50/50 chance that the kids will inherit.
Surgery can be done to remove the keloid although another large scar might form beside the previous scar.This is risky.
