SunGuard Your Skin A Lesson About Sun Safety
Learning Objectives At the completion of this program, students will be able to: • Identify three negative effects of unprotected, excessive sun exposure • Identify three risk factors for skin cancer • Identify melanoma as the most dangerous form of skin cancer • Describe three personal behavior changes that will decrease their risk for skin cancer
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)
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 MelanomaWhat 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.
Protective Measures • 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
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!
