my father always gets this white spot between his toes and we always help him clean it but it always comes back, he is a diabetic and i am concern if its a big issue or just a normal thing. i hope its not a skin cancer as i only found this category that is related to skin issues. It looks like mold and when we clean it, it stay white and it hurts him when he walks for a long distances. We went to a doctor and the doctor said there is no cure for that and gave him some cream to put on it after we clean it so it doesn't spread but to be honest we live in a country where medical services are not good so I'm seeking your help to find out what's this and if there is anything we could do to stop this
