What could be a small bump on the back of the neck?

Answer:

a cyst or start of a tumor

Answer

It's probably a cyst or possibly an ingrown hair.  Seldom does cancer strike the back of the neck.  It's best to see your doctor and let them decide if the cyst, etc., should be removed or if it's simply an ingrown hair.
