Etiology
- sun exposure
- cumulative
- history of multiple blistering sunburn
- history of sunburns in childhood
- sun exposure in both childhood & adult life increases risk for squamous cell carcinoma of the skin & basal cell carcinoma[9]
- only early sun exposure increases cutaneous melanoma risk[9]
- fair skin that burns easily, red or blonde hair, freckles
- history of skin cancer or premalignant lesions
- history of melanoma
- history of non-melanoma skin cancer
- family history of skin cancer or melanoma
- actinic keratosis
- multiple atypical nevi
- immunosuppression
- xeroderma pigmentosum
- history of phototherapy
- exposure to hydrocarbons, arsenic, ionizing radiation
- male sex
- older age
- alcohol consumption
- solid organ transpantation
- increased risk of nonmelanoma skin cancer[2]
Epidemiology
- basal cell carcinoma (BCC) most common skin cancer in whites
- squamous cell carcinoma of the skin (cutaneous SCC) may be most common in blacks
Genetics
see skin neoplasm & more specific types
Management
Treatment: see specific skin cancer
- treatment modalities used in the elderly seem to be independent of life-expectancy, functional status or comorbidities[11]
Screening: see screening for skin cancer
- insufficient evidence to recommend screening for skin cancer in asymptomatic adults without history of premalignant or malignant skin lesions (USPSTF)
Prevention
- sunscreen, SPF 30 or greater[2]
- apply 30 minutes prior to sun exposure & every 2 hours
- protective clothing
- avoidance of midday sun
- overzealous prevention strategies may result in vitamin D deficiency
- consider vitamin D supplementation[2]
- nicotinamide 500 mg PO BID may reduce risk of non-melanoma skin cancer (RR=0.73)[10]
- celecoxib may reduce incidence of both cutaneous SCC & basal cell carcinoma (BCC)[4]
- USPSTF recommends clinicians counsel fair-skinned patients aged 6 months-24 years & their caregivers about reducing exposure to ultraviolet radiation[13]
- USPSTF recommends clinicians selectively counsel older fair-skinned patients based on their existing risk factors since the net benefit is likely small[13]
Comparative biology
- strain of Staphylococcus epidermidis producing 6-N-hydroxyaminopurine on the skin of mice protected them from UV radiation-induced skin cancer[14]
- same strain of Staphylococcus epidermidis common on human skin[14]
