I think I may have a cancerous lump on/in my ear?

Then the obvious answer is to have it checked by your doctor.
It is more likely to be something that is not cancer but there is no way to know exactly what it is without getting it checked.

Is it a big lump? It might be a cyst; if you are worried consult a doctor.

Why. When did you graduate medical school?

If it is behind your ear, it is just your lymph node. Don t worry about it.

Best get it checked out. Even though it's probably nothing more than a cyst or a normal reactive lymph node, you don't want to take any chances.

I had a mysterious lump on my neck that turned out to be a metastatic lymph node. The cancer had spread there from the base of my tongue.

You're probably fine, but get a proper diagnosis.

OMG! You have the rarest kind of cancer - cancer of the earlobe!
