6. Most common form of skin cancer >2 million cases diagnosed in the US every year Areas of sun exposure most common areas to develop  Head and neck, face Can develop on any part of the body Caused by ultraviolet (UV) rays from the sun or tanning beds  Rays damage the DNA in the cells of the skin Develops after years of sun exposure  Risk increases after age of 50  BUT <50 years also develop BCC Often women who have or continue to use tanning beds Grows slowly Rarely spreads to other parts of the body BCC

7. Basal Cell Carcinoma Dome-shaped growth Visible blood vessels Pink or skin colored May have flecks of brown or black May flatten in the center Bleeds easily Crusting and oozing Patch Shiny pink or red May have slight scale Common on trunk Grows slowly May be mistaken for a patch of eczema Signs and Symptoms

8. Basal Cell Carcinoma Scar Waxy feeling Hard Pale-white to yellow color Looks like a scar Difficult to see the edges Non-Healing Sore Bleeds easily Won’t heal or heals and then returns Oozing and crusting Sunken center Visible blood vessels Signs and Symptoms

9. Basal Cell Carcinoma Physical traits  Light-colored or freckled skin  Light eyes and light hair  Inability to tan Sun history  Outdoor exposure without protection  Tanning beds Medical history  Personal history of BCC Risk of developing a second BCC increases by 40%  Close blood relative with BCC  Medications that depress the immune system  Exposure to X-rays (acne in the 1940s) Risk Factors

10. Basal Cell Carcinoma Skin evaluation by dermatologist Biopsy of suspicious lesions Excision Electrodessication and curettage Mohs surgery Photodynamic therapy (PDT) for early BCC Medicated creams for early BCC Pills  Vismodegib for advanced disease or BCC that has spread Radiation  For BCC that cannot be cut out Detection and Treatment

Squamous Cell Carcinoma Physical traits  Light skin, eyes, hair  Inability to tan Exposures  Ultraviolet exposure  Arsenic, PAHs, tobacco, heat Medical history  Diagnosed with actinic keratosis 40-60% of SCC may come from an actinic keratosis  Ulcer or sore that has been present for years  Suppressed immune system  Papillomavirus (HPV) infection  X-rays for acne Risk Factors

23. Squamous Cell Carcinoma Evaluation by dermatologist and biopsy of suspicious lesions Dependant on how deep the cancer is and if it has spread With treatment, most are cured Excision Mohs Surgery Electrodessication and Curettage for early SCC Photodynamic Therapy for early lesions Chemotherapy Cream  5-Fluorouracil cream for earliest stages Radiation Diagnosis and Treatment

25. The most serious form of skin cancer Roughly 75% of skin cancer deaths are from melanoma Can spread to other parts of the body (metastasize) Can spread quickly Can be deadly Incidence rates increasing over past 30 years Rate increased by 2.8% per year Caucasians and men >50 years are at higher risk Before age 40, incidence rates twice as high in women than in men Most common form of cancer for young adults 25-29 years old Increasing faster in females 15-29 years old than in males of same age In women <44 years, incidence rate increased 6.1% annually May be due to indoor tanning practices Statistics

38. Melanoma Skin  Fair skin  Sun-sensitive skin  >50 moles, large moles, unusual-looking moles  Tanning Sun, tanning beds, sun lamps Indoor tanning increases melanoma risk by 75% Family/Medical history  Melanoma in a family member Parent, child, sibling, cousin, aunt, uncle  Personal history of another skin cancer Especially melanoma Melanoma survivors have a roughly 9-fold increased risk of developing another melanoma (compared to the general population)  Weakened immune system Risk Factors

39. Melanoma Skin examination by a dermatologist Removal or biopsy of any abnormal pigmented lesions/spots Type of treatment depends on a few factors  How deeply the melanoma has grown into the skin  Whether it has spread to other parts of the body  Patient’s overall health Surgery Immunotherapy  Help’s patient’s immune system to fight the cancer Chemotherapy Radiation therapy Clinical trials Diagnosis and Treatment

40. Melanoma Dependant on depth and whether the melanoma has spread 98% survival at 5-years for patients whose melanoma was detected and treated before spread to the lymph nodes 62% survival at 5-years for patients whose melanoma has spread regionally 15% survival at 5-years for patients whose melanoma has spread distantly Early detection Early treatment Close follow up with your dermatologist  Every 3 months for 2 years  Every 6 months for 2 years  At least annually after 2 years Prognosis

42. Sun Avoidance Avoid peak times  Before 10 am  After 2 pm Wear sunscreen Wear sun protective clothing Even when wearing sunscreen and sun protective clothing, shade should be sought Never use tanning beds or sun lamps

43. Sunscreen 2010: daily sunscreen use cut incidence of melanoma in ½ Everyone should wear  All skin types develop skin cancer Every day if going to be outside  80% of rays can penetrate the skin on cloudy days Snow, sand, and water reflect the sun’s rays General Facts

44. Sunscreen Broad spectrum  Ultraviolet A and Ultraviolet B (UVA & UVB) Sun Protection Factor (SPF) of at least 30 Water and sweat resistant products Don’t forget lips, ears and scalp Apply enough of it!  Most people only apply 25-50% of recommended amount  1 ounce or enough to fill a shot glass May need more depending on surface exposed Apply BEFORE going outdoors  15 minutes Re-apply sunscreen  Every two hours  After swimming or sweating heavily What to look for and how to apply

45. Sun Protective Clothing Ultraviolet Protection Factor  UPF  Fibers may be treated with reflective components Tighter woven clothing  If you can see through it, the sun can get through it Hats  Wide brimmed  Protect neck and tops of ears

50. Vitamin D Required for bone health Evidence linking Vitamin D with other health benefits (such as cancer and cancer survival) have been inconsistent, inconclusive, and insufficient Obtained from diet and sun  Diet: available year round  No increased risk of skin cancer  Fortified mild, cheeses, yogurt, cereals  Oily fish: salmon and tune Amount from sun is inconsistent AND increases the risk of skin cancer American Academy of Dermatology recommendations  Sun NOT a recommended source of vitamin D  Talk to your doctor about diet and supplements 600IU ages 1-70 years 800IU ages >71 years
