WILMA, a six-year-old female, is born with a significantly whiter complexion than the rest of her family members. Despite her Filipino ancestry, she has pasty and white skin, lighter colored hair, and blue eyes. Additionally, her family noticed that no matter how much she is exposed to the sun, she only becomes redder, not darker. When they decided to take her to the doctor's clinic to learn more about her condition, they were informed that she had albinism. Give the 3 most common types of skin cancers and differentiate them as to the type of cell involved, common areas of skin affected, involvement to sunlight exposure, and prognosis.

Watch the film from time stamp 12:19 minutes to 13:32 minutes. Pause when Dr. Jablonski says, “That is what melanin does.” In this segment of the film, Dr. Jablonski references a paper she had read about the connection between UV exposure and the essential nutrient folate (a B vitamin), which circulates throughout the body in the blood. The paper, published in 1978, describes how the serum (blood) folate concentrations differed between two groups of light-skinned people. You will now look at one of the figures from that paper. Figure 3. Folate Levels in Two Groups of People. In one group (“patients”), 10 individuals were exposed to intense UV light for at least 30–60 minutes once or twice a week for three months. Sixty-four individuals not receiving this treatment (“normal”) served as the control group. The difference between the two groups was statistically significant (p < 0.005). Brackets represent the standard error of the mean, and “ng/mL” means “nanograms per…
Aaron, a 3-month-old boy, was just diagnosed with a rare genetic immunodeficiency condition. Aaron's parents voiced concern about Aaron's facial features at a recent pediatric examination, noting that they do not resemble those of their two older children.
