Background:
The purpose of this study was to determine the numeracy information included in three prominent breast cancer Web sites.
Methods:
A content analysis was performed, grouping numeracy items into 15 categories. Interrater reliability was high.
Results:
Of the 3,206 items identified, 14.3% were numbers, 33.9% were descriptive measures (e.g., many, lower), 27.3% were statistical terms (e.g., predictive, risk), and 12.4% were temporal terms (e.g., before, always).
Conclusions:
Findings suggest that there is an abundance of numeric information presented in breast cancer Web sites, much of which may be conceptually too advanced for the intended audience.

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.
Such genes that act...
