Hello Trese:
I sent you a PM earlier, but not sure it got to you because you weren't on the Forum at the time. What I suggested was going to a dermatologist for your lip pimple and let them check it out. Most would do a biopsy if it looks even close to suspicious. You could mention your other symptoms and they might refer you to a different doctor. It's a terrible feeling to be so worried and not be able to get a "definite" answer, but as others have posted, they have been through similar situations. I am going through something similar now, but not cancer associated, and I think I've been to the majority of ENTs and gastro doctors in my area, to no avail. Anyway, try the dermatologist, and let us know what happens.
