Skin CancerA report in the August 10, 2005 issue of The Journal of the American Medical Association found that the incidence of basal cell carcinoma and squamous cell carcinoma is up both in young men and young women, but that the rates have nearly tripled in women under age 40 since the late 1970s. Researchers suggest increasing incidence is likely due to a combination of factors, including increased exposure to UV light, ozone depletion, and increased surveillance. And risk factors include long-term exposure to the sun resulting in photodamage, certain genetic defects (e.g. basal cell nevus syndrome and xeroderma pigmentosum), smoking, and the use of tanning beds. An earlier study, published in the July 20, 2005 issue of the Journal of Clinical Oncology had reported that rates of melanomas in children are increasing rapidly, increasing 46% per year of age and 2.5% per year from 1973 to 2001. CataractsIn a study of 445 men aged 50 or older, researchers found that pilots had triple the risk of developing cataracts that men who were not pilots. The research, published in the August 2005 issue of Archives of Ophthalmology points the finger of blame at cosmic radiation exposure. FatAccording to a study published in The Journal of Nutrition, rats who ate a high-fat diet showed reduced sensitivity to fullness signals provided by the hormone cholecystokinin, which is secreted by the small intestine. As a result, the rats on the high-fat diet didn't know when to stop eating. Discuss This ArticleHave something you'd like to say? Tell us what you think! Read and post comments for this article.
