People With Darker Skin Still at Risk for Melanoma

WEDNESDAY, July 25 (HealthDay News) — Skin cancer is more common
among white people, but people with darker skin are also at risk, a
dermatology expert cautions.

While the skin pigment melanin does offer people with dark skin some
natural protection against harmful ultraviolet rays and sunburns, this
protection is not perfect and too much sun exposure over a lifetime can
lead to a high risk for skin cancer, said Dr. Valencia Thomas of the
Harris County Hospital District, in Texas.

Using sunscreen with a high sun protection factor (SPF), regularly
checking your own skin and having yearly skin check-ups are important for
preventing skin cancer or catching it early if it does occur, Thomas
advised.

One in five Americans will be diagnosed with skin cancer this year,
according to the American Academy of Dermatology. Over the past 30 years,
rates of the deadliest form of skin cancer — malignant melanoma — have
increased among all races in the United States. The disease kills 22
people a day across the country.

“In African American and Asian populations, malignant melanoma is most
commonly located on hands and feet, while among Caucasians [whites] and
Hispanics, it’s found on the legs and back,” Thomas said in a hospital
district news release.

“Although excess ultraviolet radiation is a risk factor for developing
malignant melanoma in Caucasians, the role of these rays among ethnic
populations is not well known. People with new or changing moles that have
irregular borders, color and appear bigger than a pencil eraser should get
them examined immediately,” advised Thomas, who is director of dermatology
at the Lyndon B. Johnson General Hospital and Quentin Mease Community
Hospital, and an assistant professor at the University of Texas Health
Science Center, in Houston.

Other common types of skin cancers are basal cell carcinomas and
squamous cell carcinomas. Basal cell carcinomas appear as a growing bump
with blood vessels, which tend to bleed easily and in ethnic populations
may be dark brown or black. This type of cancer tends to appear in the
head and neck area. Basal cell carcinoma is most common among Hispanics
and Asians, and second most common among blacks and South Asian
Indians.

Squamous cell carcinoma is most common among South Asians and blacks
and appears as firm bumps, sometimes with thick scale. Among South Asian
Indians and blacks, this type of skin cancer is found on the legs or the
genital areas, Thomas said. This type of cancer is strongly linked to sun
exposure.
