Abstract:
A majority of U.S. adults report feeling overwhelmed by the amount of available cancer information, termed cancer information overload (CIO). Research has demonstrated CIO is prevalent and negatively related to health behaviors, but no study to date has examined this disposition across time. Two longitudinal studies - a colonoscopy intervention among older U.S. adults (N = 237) and an HPV vaccination intervention among young U.S. women (N = 411) - were utilized to examine CIO stability across time and its relationship to prevention intentions and indifference. CIO increased indifference for non-adherent individuals but had no effect on intentions. CIO was stable in study 1 but not study 2, suggesting CIO stabilizes across the life course. Results also support a five-item measure of CIO.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
