1 in 5 people will be diagnosed with a skin cancer during their lifetime. UV light that comes from the sun and tanning beds are the main risk factor for developing skin cancer.
The two types of Ultra Violet radiation are UVA and UVB. Both of these UV rays penetrate the skin and cause damage to the underlying cells.
UVA can penetrate more deeply in the skin causing damage to the normal genetics of our cells. This affects not only skin cells that can lead to cancer, but also breaks down the support structures in our skin. UVA leads to premature aging and wrinkling.
UVB penetrates less deep, into the top layer of the skin causing damage to the cells there. The pain you feel when sunburned is actually the body’s response in attempt to repair the damage. UVB causes cumulative damage to the DNA in our skin cells. While the body is good at repairing itself when damage occurs, some abnormal cells may be left behind. Over time damage to the genetic material can cause uncontrolled growth of these abnormal cells, resulting in skin cancer.
You can protect yourself by:
• Use a broad spectrum sunscreen (protects against UVA and UVB rays.) Use a sunscreen with a SPF or sun protective factor of at least 30. Reapply approximately 1oz of sunscreen every 2 hours.
• If using a spray sunscreen, MAKE SURE TO RUB IT IN.
• Limit sun exposure during hours when the UV rays are the strongest, between 10AM and 4 PM
• Wear protective clothing, sunglasses and a wide brimmed hat.
• Avoid tanning beds
• Have an annual skin exam performed by a dermatologist.
• Do self-skin exams, using the ABCDE's every month, and look for new or changing moles.
