- 7. What Causes Skin Cancer • Ultraviolet (UV) radiation is the main cause • Artificially-produced UV radiation • Chemicals
- 8. Types of Skin Cancer • Pre-Cancerous – Actinic keratosis • Cancerous – Squamous cell carcinoma – Basal cell carcinoma – Melanoma – Others
- 9. Actinic Keratosis • A pre-cancerous condition of thick, scaly patches of sun-damaged skin.
- 10. Squamous Cell Carcinoma • Begins in squamous cells which are found in the surface of the skin • They are thin, flat cells that look like fish scales – Approximately 20% of all skin cancers
- 11. Squamous Cell Cancer Warning Signs Scaly Red Patch Elevated with Central Depression Sore that Persists
- 12. Basal Cell Carcinoma • Skin cancer that arises from basal cells, small round cells found in the lower part of the skin (epidermis). – Over 75% of all skin cancers – Slow-growing – Generally treatable
- 13. Basal Cell Cancer Warning Signs Small, smooth, pale, or waxy shiny lump Firm, red lump A lump that bleeds or develops a crust
- 14. Check In Quiz Thick, scaly patches of sun-damaged skin #1 #2 Persistent, scaly red patch sometimes crusts or bleeds #3 Red growth with indentation in center
- 15. Melanoma • A skin cancer that arises in a pigment producing cell • Usually begins in a mole • Deadliest form of skin cancer – 5% of all skin cancers – Can be found anywhere on the body
- 16. Benign Mole or Melenoma NORMAL How Do I Tell The Difference? ABNORMAL
- 17. ABCDEs of Melanoma Screening “A” = ASYMMETRY NORMAL ABNORMAL
- 18. ABCDEs of Melanoma Screening “B” = BORDERS NORMAL ABNORMAL
- 19. ABCDEs of Melanoma Screening “C” = COLORS Uniform Color NORMAL ABNORMAL Multiple Colors
- 20. ABCDEs of Melanoma Screening “D” = DIAMETER NORMAL ABNORMAL <6mm >6mm
- 21. ABCDEs of Melanoma Screening “E” = Elevation NORMAL ABNORMAL Raised Area Flat Area
- 22. How is Skin Cancer Found? • Self-examination • Exams and Doctors visits • Early detection is KEY
- 23. Treatment • The Physician will: – Review medical history and perform a physical – Determine what type of cancer – Then treat the cancer with: • topical medication • laser, freezing, and various surgeries • radiation and/or chemotherapy
- 24. Prevention • Avoid Artificial Sun – Tanning/sun lamps • Limit Sun Exposure • Avoid midday sun • Apply sunscreens often (at least 30 SPF) • Use UVA/UVB blocking SUNGLASSES
- 25. Remember Clouds DON’T protect you! Sand, water, snow, and ice magnify exposure Increased altitude = increased exposure
- 26. What else can you do? • Ask for complete skin exam with physical • Do not self-diagnose, see your doctor right away if you find: – A new mole in an adult – A sore that doesn’t heal – A suspicious change in the appearance of any skin feature – A mole fails the ABCDE screening
