[Vitamin A: an indirect factor in the prevention of cancer]
Abstract:
Although vitamin A intervenes essentially in the mechanism of sight, its possible role in the prevention and treatment of cancer is widely discussed. Epidemiological studies have demonstrated a correlation between vitamin A deficiency and an increase in the frequency of cancers in man. Several hypotheses have been put forward concerning the mechanism of interaction between vitamin A and cancer on the basis of experimental models showing that vitamin A exerts a protective action against spontaneous or induced neoplasias in animals. The toxicological aspects of vitamin A administration and the relevance of these experimental results to human oncology are discussed.

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
Cancer Vaccines
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
