I identify most with skin cancer among Caucasians, especially since my skin is so ghostly pale and I feel more susceptible to the sun’s rays. I think skin cancer is so prevalent among Caucasians because our lighter skin is easier for UV rays to penetrate. There is a reason that the native populations along the equator generally have dark skin. This is because these populations produce more melanin which makes their skin darker. The darkness of their skin is more difficult for UV rays to penetrate which protects these populations from massive death counts for cancer. Their skin is a naturally adapted and evolved trait that enables them to live in extremely hot climates. African Americans that have strayed from these climates may have lost some of this protection, but I believe that they still have a large advantage over Caucasians.
Race cannot be scientifically determined, it is more a matter of self-identification, so it really has no sound structure in the determination of one’s health. Race is helpful in discovering possible ancestry to determine one’s health, but it is very subjective. There may be genetic clustering in different areas of the world, but this may be just as much a result of the environment as of race. Race cannot account for all the complexities of human genetic variation. Genetics, on the other hand, is a large, scientifically-proven component in one’s health. A disease may be inherited through generations and may plague one particular population, not because of race, but simply because they are a native people that have never expanded outside of their immediate area. This may more often be the case in cultures near a continental barrier that physically prevents their expansion such as the Himalayas or the Sahara desert. Many scientists have also shown that genetic distance is strongly related to geographic distance between populations. There is clearly a geographic structure to human genetic variation that holds greater weight than race.
