The lump behind your ear could be swollen/infection from wisdom teeth coming in. And you could be noticing everything else that is normal or stress related, because you have yourself so worked up.
Cancer is a very worrisome burden to be keeping to yourself. I hope you have someone to talk to. You should be checked out as soon as possible to rule out all the possibilities. I hope everything works out for you. Best of luck.
