Help it’s about my boob

So my nipple on the right feels like ... yk when you’re so cold so it hardens up and gives you that sore feeling ? Yea it feels like that but its not as getting hard it gets there but idk.. and it hurts ? but like in an uncomfortable way .. it feels like somethings wrong w it . like im like just laying down or on my sides or cold , or like slightly swiping past it and it begins to hurt for a bit. I wanna know if its normal to feel this way and if its not could it be breast cancer cos im scared
