i have a strange lump on my arm. what should i do?
user
i’m happy to help, but i think it would be better if we got you a doctor to take a look at the lump.
assistant
what will the doctor do?
user
he or she will probably examine the lump and, depending on what you and the doctor decide to do, a biopsy might be done.
assistant
All right, what if my doctor determines it's not cancer but i'm not convinced?
user
I can help you think about what other options you have.  In your case, I think you'll probably want to start with a dermatologist.  Is that right?
