I think it was great that you saw a second doctor (and please, please, please don't take this the wrong way), but it does sort of sound like you found a doctor who told you what you wanted to hear, and then you went home, and now you're still worried about it. Would it maybe be helpful to you to get even a third opinion? That way you won't have that awful first doctor's voice in your head suggesting you have cancer all the time, and maybe then you'll feel reassured that it really is nothing to worry about.
Good luck! I hope you feel better!
