Background:
Brief pictograph measures of health functioning have clinical value to office-based practice. Many women with a close family history of breast cancer will experience worry about their risk of developing breast cancer that influences decision-making and can interfere with health-related functioning.
Purpose:
To develop a clinically - useful triage measure of breast cancer worry for the field setting of office based practice.
Design:
qualitative pilot testing followed by mailed survey.
Survey Sample:
women registered with the Cancer Genetics Network who have a first or second-degree family history of breast cancer and no personal history of any cancer. Novel measure: single pictograph item modeled upon the Dartmouth COOP Charts. Comparison gold-standard measure: four-item Cancer Worry Scale (CWS).
Results:
Pilot testing: participants found the item to be easily understood, rapidly completed and unobtrusive. Quantitative: 469 women responded (78% response rate); the Cancer Worry Chart demonstrated strong correlation to the CWS (Pearson correlation coefficient: 0.66, P < 0.001); Receiver operator curve identified favorable characteristics (AUC = 0.86) of the Cancer Worry Chart for identifying cancer worry-related mood or social role dysfunction.
Conclusions:
The new Cancer Worry Chart is a valid triage measure for breast cancer worry.

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...
