What potential health issue can exposure to ultraviolet light cause if not managed properly?

Exposure to ultraviolet (UV) light, particularly from sources like the sun or tanning beds, can lead to a range of serious health issues, with skin cancer being one of the most significant concerns if proper precautions are not taken. UV radiation can damage the DNA in skin cells, leading to mutations that can cause these cells to grow uncontrollably. Over time, this uncontrolled growth can result in various forms of skin cancer, including melanoma, basal cell carcinoma, and squamous cell carcinoma.

It’s crucial to understand that while other options may describe effects of UV exposure—such as dry skin, acne, or sunburn—they do not carry the same level of long-term health risk as skin cancer. Sunburns might indicate overexposure and can be painful, but the more critical issue is the cumulative damage caused by UV radiation, which increases the likelihood of developing skin cancer later in life. Therefore, the importance of protective measures such as sunscreen, clothing, and avoiding excessive sun exposure cannot be overstated in preventing skin cancer.
