I would think it would take longer for it to heal. When he falls and gets hurt that is a different kind of wound than having the mole removed. They had to go in deeper and probably had to use stiches which will take longer to heal. Do exactly what your doctor said and if you still think it is taking to long or just doesnt look right, call the dr or take him back in. I know you are scared right now (who wouldnt be!!!) Use your best judgement. Be proud that you got it early. You and your son will be in my prayers. Good luck!
