Which warning sign involves changes in a mole?

• A. Nonhealing Sore
• B. Change In Moles
• C. Nagging Cough
• D. Weight Gain

Answer: (B)

The key idea here is recognizing signs that a mole is changing over time. Melanoma, a serious form of skin cancer, is often first spotted when a mole that you already have begins to evolve in appearance. That evolution can show up as changes in size, shape, color, or elevation, and it can also include itching, crusting, or bleeding. Because these changes signal that a mole is no longer behaving normally, they warrant prompt medical evaluation.

The option that talks about changes in moles directly matches this important warning sign—moles that change in any of these ways can be a clue to melanoma. The other options refer to warning signs for cancer in other parts of the body or for conditions not specific to mole changes (for example, a nonhealing sore can indicate skin cancer in general, but it’s not about a mole changing, while a nagging cough or weight changes point to other health concerns). If you notice a mole that is changing, it’s wise to have it checked by a clinician.
