What Is Your Skin Cancer IQ?

May is National Skin Cancer Awareness MonthWhat Is Your Skin Cancer IQ?Identifying BCC, SCC, and melanoma

Basal Cell Carcinoma (BCC)

Squamous Cell Carcinoma (SCC)

Melanoma

Appearance

Small, shiny bumps or nodules that are red, pink, or white; persistent, nonhealing sore; reddish flat patch; or a scar-like white or yellowish area

Red, scaly patches or bumps

Asymmetrical, mottled patches with notched or blurred borders, typically in tan, brown, or black

Size

Takes many years or months to reach a half-inch

Can reach up to three-quarters of an inch to an inch

Usually greater than 6 mm

Location

Head, neck, hands, and occasionally on the trunk of the body

Face, ears, neck, lips, and back of the hands

Can occur anywhere on the body, most frequently on the upper back or legs, as well as the head and neck

Progression

Grows slowly and may bleed, crust over, then the cycle repeats

Can develop into large masses

Can appear without warning, or may begin in or near a mole or other dark spot on the skin

Potential for metastasis

Rare, but can grow into nearby areas and may invade bone and vital structures, such as the eye

Can metastasize, and may be fatal if not treated

Can metastasize, and is deadly if not treated

Prevalence

BCC accounts for 80% of all skin cancers (more than 800,000 new cases each year).

SCC accounts for 16% of all skin cancers (approximately 250,000 new cases each year). About 2,500 deaths from SCC are expected during 2007.

Melanoma accounts for 4% of all skin cancers (approximately 59,940 new cases each year). More than 8,110 melanoma deaths are expected during 2007.
