Itchy nipples

Recently my right nipple has been really itchy lately and one day i was about to get it the shower and i looked at it (my nipple) because it felt kind of hard and i discovered that it had this kind of crust on the areola. So i took the crust off and washed my nipple really good. i washed all my bras to see if that was the problem , but then about 2 days later it started itching again so i looked at it and it had the same crust on it mostly on the areola. i kind of looked into what it might mean and it said i might have breast cancer ! im only 14 and i just want a couple of insights as to what the hell is going on with my nipple !
