Weird bump (TMI) HELP

Yesterday the area around my butt was hurting and feeling weird but i dismissed it thinking it was because of my panties, but today it was still hurting so i decided to check. I found a weird bump (not tiny but noticeable) on my anus. Its not soft, when i touch it its quite hard. I am going to the doctors later today or tomorrow, but wanted to ask people on here if they ever had it as well. Is it a hemorrhoid or should i be worried? I read online that it could also be cancer. I’m 17 btw so its a bit weird to have hemorrhoids at my age.
