  2. Skin Cancer: Warm-Up #3 Complete the “Are you at Risk” WS

  3. Today’s Vocabulary • Cancer: uncontrollable growth of abnormal tissue • Environment: the sum of your surroundings • Health Skills: specific tools and strategies to maintain, protect, and improve all aspects of your health • Prevention: taking steps to keep something from happening or getting worse

  4. Skin Cancer FACTS • Skin cancer is the most common type of cancer in the U.S. and accounts for approximately 50% of all cancers. • The incidence of skin cancer is greater than breast, lung, prostate, colon, and kidney cancers added together. • One in five Americans will develop skin cancer in their lifetime. • About one million people are diagnosed with skin cancer every year in the U.S. • One American dies every hour from skin cancer.

  5. Types of Skin Cancer • Basal cell carcinoma • Squamous cell carcinoma • Melanoma

  6. Basal Cell Carcinoma • Most frequently diagnosed skin cancer • 2.8 million every year in US • Occurs in heavily sun-exposed areas of the skin • Usually appears on face, neck, ears, lips, & nose • Rarely results in death, but can spread & cause more serious health problems

  7. Basal Cell Carcinoma • Typically occur as light pink or flesh-colored bumps with pearly or waxy appearances • They grow slowly and are almost never fatal but, if neglected, can grow to the point where disfiguring surgery is necessary to remove them

  8. Basal Cell Carcinoma • Although common in all areas of the county, it is especially prevalent in southern states

  9. Squamous Cell Carcinoma • Second most common skin cancer • 700,000 cases every year in US • More aggressive than basal • Can spread to other parts of the body • May result in death (2,500/year) • Tends to occur in the most heavily sun-exposed areas of skin

  10. Squamous Cell Carcinoma • Often start as flat red or brown splotches which become rough, dry, and scaly • If not treated, my eventually grow large enough to spread to nearby internal organs and be fatal

  11. Squamous Cell Carcinoma • Occurs in all areas of the country, but is more prevalent in southern states

  12. Basal & Squamous Cell Carcinomas • Approximately 1 million cases of basal & squamous cell carcinomas are diagnosed each year in the U.S.

  13. With early detection and treatment cure rate of more than 95%

  14. Melanoma • Malignant melanoma is the most deadly of the three types of cancer • Melanoma accounts for less than 5% of the skin cancer cases • Causes more than 75% of the skin cancer deaths • Causes about 8,790 deaths each year in U.S.

  15. Melanoma • Melanoma cases are increasing faster than any other cancer • Melanoma is the most common cancer among 25-29 year old and second for 15-29 year olds • Vulnerability to melanoma begins at age 12, much earlier than other skin cancers

  16. Melanoma • If not removed early, while thin, melanoma often grows rapidly, spreads to distant internal organs and is fatal • It is equally likely to occur in all areas of the country.

  17. Ordinary Moles ORDINARY MOLES have all of these features: • Round or oval shape • Sharp, even borders with skin • Uniform color (usually brown) • Less than ¼ inch wide • Cauliflower or smooth surface • Even dome shape if mole raised

  18. Atypical Melanoma Moles ATYPICAL MOLES often have one or more of these features: • Irregular shape • Uneven and/or fuzzy borders with skin • Two or more shades of brown or pink • ¼ inch wide or more • Cauliflower or smooth surface • Flat edges with “fried egg” center if mole is raised

  19. Risk Factors for Skin Cancer • Fair skin • Light hair color • Family history of skin cancer • Blistering sunburn before age of 20 • Atypical moles • Indoor tanning • Large number of normal moles

  20. Controllable Risk Factors

  21. Does where we live matter? Figures, rounded to the nearest ten, are from American Cancer Society Cancer Facts & Figures 2011.

  22. UV Index • Ultraviolet Rays (UV)—the ozone layer shields the earthy from harmful UV radiation • Ozone depletion , weather & the seasons cause different amounts of UV radiation to reach the earth

  23. Sun Smart • In your group, discuss and record ways to reduce your chances of skin cancer.

  24. Exit Ticket • List all of the warning signs which may be possible indications of melanoma. • List all risk factors which increase your risk of melanoma.
