The Structure of Your Skin The skin is your body’s largest organ It protects you from the sun and from infections The skin has 3 layers: epidermis, dermis and subcutis Skin color depends on the activity of the melanocytes in the epidermis Picture from http://www.sunsafecolorado.com/home/uvradiation/uv_uvauvb.shtml (Sun Safe Colorado)http://www.sunsafecolorado.com/home/uvradiation/uv_uvauvb.shtml
UV Radiation Many types of rays come from the sun: Heat rays, visible light, and invisible ultraviolet light or UV radiation Two kinds of UV radiation reach the earth: UVA rays – longer rays, penetrate skin deeply, and cause wrinkling and tanning UVB rays – shorter rays which cause burning of the skin Tanning and burning of the skin are signs of skin damage!
The Dangers of UV Radiation Overexposure to UV Radiation causes: Sunburn DNA Damage Skin Cancer Premature aging (wrinkles) Cataracts Immune system depression
Skin Cancer Facts Skin cancer is the most common cancer but also the most preventable Childhood sunburn is the most common cause of skin cancer More than 3,000,000 skin cancer cases are diagnosed in the US each year One in every two cancers is skin cancer One in every five Americans will develop skin cancer in their lifetime
What Causes Skin Cancer? UV radiation causes increased activity in the melanocytes This increased activity is the cause of freckles, tanned skin and sunburns Sometimes this leads to changes in cell structure and function, causing cancer
Do You Know the Three Main Types of Skin Cancer? Basal Cell Carcinoma 75% of all skin cancers Squamous Cell Carcinoma 20% of all skin cancers Melanoma 5% of all skin cancers but responsible for 75% of skin cancer deaths
Signs of Melanoma What are the ABCD’s? Asymmetry Border Color Diameter CHANGE!
Who is at Risk for Skin Cancer? Fair skin, burns easily Light hair color Blue or green eyes Freckles Many moles Family history of skin cancer
When is UV Radiation Most Intense? In the middle of the day (Between 10 a.m. and 4 p.m.) During the summer months At higher altitudes In regions of the earth closer to the equator Use the UV Index as a tool to help plan your outdoor activities.
Avoid midday sun Cover up with hats, clothing and sunglasses Use sunscreen Apply liberally and often Avoid reflective surfaces Seek shade when your shadow is shorter than you are Avoid tanning beds Protective Measures
Tanning Beds are NOT Safe! Studies show tanning beds are linked to skin cancer and premature aging Indoor tanning lamps emit UVA and UVB radiation at levels that can be as much as 15 times stronger than the sun Minors (under the age of 18) must have in-person, written parental consent before using a commercial tanning facility If you must be tan, use a self tanner You still must use sunscreen Remember: There is no such thing as safe tan!
