What effect does chronic exposure to ultraviolet (UV) rays have on the skin that increases the risk for skin cancer?
Decreases the water content of the skin
Causes an error in the skin’s genetic code
Increases in blood flow to the skin
Causes degeneration of elastic fibers in skin tissue.
The Correct Answer is B
Choice A rationale
While chronic exposure to UV rays can cause skin dryness, it does not decrease the water content of the skin20. Skin dryness is more of a symptom rather than a risk factor for skin cancer20.
Choice B rationale
Chronic exposure to UV rays can cause an error in the skin’s genetic code20. This can lead to the development of skin cancer, as the damaged DNA can lead to uncontrolled cell growth20.
Choice C rationale
Increased blood flow to the skin is not a direct result of chronic exposure to UV rays20. While UV rays can cause skin redness and inflammation, these are not directly linked to an increased risk of skin cancer20.
Choice D rationale
Chronic exposure to UV rays does not cause degeneration of elastic fibers in skin tissue20. While UV rays can cause skin aging and wrinkles, these are not direct risk factors for skin cancer20. Diabetic retinopathyDiabetic retinopathy Explore
