Final answer:
UV radiation from the sun can cause skin cancer by damaging the DNA in skin cells, leading to mutations and uncontrolled cell growth. UVB radiation is especially harmful as it affects DNA directly. Preventative measures like using sunscreen and wearing protective clothing are crucial to reducing the risk of skin cancer.
Step-by-step explanation:
How Light from the Sun Can Cause Skin Cancer
The sun emits ultraviolet (UV) radiation, which is a significant factor in the development of skin cancer. When UV rays reach the skin, they can damage the genetic material, DNA, in skin cells. This damage can cause mutations that lead to uncontrolled cell growth, and in some cases, the formation of cancerous tumors. In particular, UVB radiation can be quite harmful, as it has enough energy to directly affect DNA and is primarily responsible for sunburn and contributing to skin cancer risk.
There are several other risk factors for developing skin cancer, including having light-colored skin, a large number of moles on the body, or a family history of the disease. It is particularly concerning that children and teens who suffer from severe sunburns are at a higher risk for skin cancer later in life. Similarly, long-term exposure to UV radiation is among the top contributors to the condition.
To reduce the risk of skin cancer, it is important to take preventative measures such as applying sunscreen with a high SPF, wearing protective clothing, and minimizing exposure to UV radiation during the sun's peak hours. By taking these steps, you can help protect your skin from the cancer-causing effects of UV light.
