Francesca has always had a mole on her arm, but during a recent self-exam, she notices that it seems to have grown a bit in size and now has an irregular border. Should she make an appointment with her dermatologist to have it checked? A. No, because moles that have always existed on your body cannot at any time suddenly change and become cancerous.
B. No, because the mole is not pearly, tan, or multicolored, and only moles that fit that description are likely to be cancerous.
C. Yes, because all moles, birthmarks, or brown spots on the skin are most likely cancerous and need to be removed.
D. Yes, because any mole that changes in size or appearance needs to be checked to make sure it is not cancerous.​
