What percentage of all skin cancers is caused by sun exposure?

  1. 50%

  2. 75%

  3. 90%

  4. 100%

The correct answer is: 90%

The correct answer indicates that 90% of all skin cancers are caused by sun exposure, which highlights the significant role that ultraviolet (UV) radiation plays in the development of skin cancer. This statistic underlines the importance of sun protection measures, such as wearing sunscreen, protective clothing, and seeking shade, especially during peak sunlight hours. By understanding that a substantial majority of skin cancers can be attributed to UV exposure, estheticians can emphasize preventative care to clients, educating them on how to protect their skin from the damaging effects of the sun. The rationale behind the question also emphasizes the critical role sun exposure plays in skincare education and practices, reinforcing the need for estheticians to be knowledgeable advocates for sun safety. The figure of 90% serves as a compelling reminder of the impact of environmental factors on skin health and disease prevention. This knowledge is essential for informed discussions and recommendations for clients seeking to maintain healthy skin.
