Fact
Any change in skin color is a sign of damage from UV radiationSlide10
Fact
More than 90 percent of the visible changes commonly attributed to skin aging are caused by the sunThe most potent anti-aging product is sunscreenSlide11
Fact
The major risk factor for developing skin cancer is ultraviolet lightSlide12
Actinic keratosesSlide13
Incidence
Skin cancer (abnormal growth of skin cells) is the most common form of cancer in the U.S.More than 3.5 million skin cancers are diagnosed annually1 in 2 men and 1 in 3 women in the US will develop NMSC in their lifetimeBy 2015, 1 in 15 Americans will develop melanoma in their lifetimeSlide14
Most common skin cancers
Basal cell carcinoma80% of all non-melanoma skin cancersSquamous cell carcinoma20% of all non-melanoma skin cancersMelanomaSlide15
Basal cell carcinoma
Intermittent, intense sun exposure (sunburns; blistering)Fair complexionRed hairTans poorlyFamily

Basal cell carcinoma
Spread to other organs is rare (0.0028-0.55%)But can be locally destructiveSlide17
Squamous cell carcinoma
2nd most common skin cancerChronic long-term sun exposureSlide18
Higher
risk of spreading to other organs (0.5-5.2%
)
BCC and SCC have cure rates of 95% if detected and treated early
Squamous cell carcinomaSlide19

Melanoma survival
5 year survival rates for melanomas detected and treated prior to spread to lymph nodes is 95%Drops to 7.5% for distant metastatic disease75% of skin cancer deaths are from melanomaSlide23
Other risk factors
Light complexionLight eyesBlonde or red hairMany frecklesTan poorly/sunburn easilyMany moles
Genes
Indoor tanning
Blistering sunburns
Men’s backs
Women’s lower legs
Cumulative

radiation
Face
Tops of hands
Tops of forearmsSlide24
Are runners at increased risk?
210 runners vs. 210 non-runnersRunners had:More atypical moles
More BCCs and SCCs
More solar
lentigines
All risk factors for melanoma
The more miles runners ran, the more skin lesions they had
Only 56% of runners reported regular sunscreen useSlide25
