What are risk factors for an individual to develop melanoma?
Having greater than 50 moles and green or blue eyes
Intermittent claudication and diabetes
Black or brown hair and darker pigmented skin
Younger than 18 years of age and obesity
The Correct Answer is A
A. Having greater than 50 moles and green or blue eyes:
Risk factors for melanoma include having many moles, fair skin, light-colored eyes, and history of sunburns.
B. Intermittent claudication and diabetes:
These are vascular and metabolic problems, not related to melanoma risk.
C. Black or brown hair and darker pigmented skin:
Darker skin provides some natural protection against UV radiation, reducing melanoma risk (although melanoma can still occur).
D. Younger than 18 years of age and obesity:
Age under 18 and obesity are not primary risk factors for melanoma. Cumulative sun exposure and genetic predisposition are much more relevant.
