I have found through experience that most GPs can’t tell a freckle from keratosis from skin cancer. They will admit they don’t know, and send you to a dermatologist right away. The dermatologist will glance at it and tell you immediately what it is.
Maybe the gatekeeper can be an RN who performs a standard battery of simple diagnostic procedures, but there has to be something or else everyone is going everywhere to figure out what the heck they have.
Not all symptoms are skin deep.
