a friend was telling me how overblown concern about skin cancer tends to be. apparently it's over-diagnosed and not counted in a lot of cancer stats.
but didn't know this...people of color are likely to get skin cancer in places that are NOT exposed to the sun. seems worth knowing. pardon my caucasian!
"In Caucasians and to a lesser extent, Hispanics, melanomas predominantly occur in sun-exposed skin, whereas in Asians and Blacks, UVR does not appear to be a significant risk factor, and the majority occur in non-sun-exposed skin (ie—subungual, palmar and plantar surfaces, mucus membranes) (Bradford et al, 2008) (Table 3). Oral melanomas represent ~7.5% of all melanomas in Asians, and two-thirds of these tumors arise from oral melanosis (Collins, 1984). In non-whites, the plantar portion of the foot is often the most common site, being involved in 30–40% of cases. People of color also have higher percentages of acral lentiginous melanoma (melanoma of the palms, soles, and nailbeds) than Caucasians (Bradford et al, 2008), whereas superficial spreading melanoma is the most frequent subtype in Caucasians and Hispanics (Byrd-Miles et al, 2007)."
