Which option best exemplifies a cancer warning sign listed?

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

Answer: (D)

Cancer warning signs are symptoms that should prompt medical evaluation because they may indicate abnormal growth or tissue changes. A persistent nagging cough can signal issues in the lungs or airways; a sore that does not heal points to ongoing abnormal tissue activity; a noticeable change in a mole can indicate skin cancers such as melanoma. Weight changes can occur with cancer, but unintentional weight loss is more commonly emphasized as a warning sign, whereas weight gain is not typically listed. So, among the options, the nagging cough, the nonhealing sore, and the change in a mole are the signs that align with common cancer warning signs, while weight gain does not fit this pattern.
