Mammographic screening in asymptomatic women aged 40 years and older
Article Abstract:
Different age groups of women without symptoms of breast cancer receive different recommendations as to the value of screening mammograms, or breast x-rays, to detect cancer. Research shows that mammograms of asymptomatic women aged 50 years or older can reduce the death rate from breast cancer. This study suggests that mammograms of younger age groups, such as asymptomatic women aged 40 to 49, also reduce mortality rates and increase survival rates from breast cancer. Early detection of breast cancer is most effectively done by a mammogram, although some breast cancers may develop between mammograms. The costs of mammographic screenings, which range from $25 to $250, should be considered when governmental and other organizations make recommendations to women regarding screening mammograms.

The cost-effectiveness of mammographic screening strategies
Article Abstract:
Cost and level of effectiveness should guide decisions on the type of mammography program used to screen for breast cancer. A model was adapted to compare women screened for breast cancer using mammography to women who were observed but not screened. Marginal cost per year of life saved (MCYLS) was calculated as a measure of cost effectiveness. Researchers determined that the most effective screening method used biennial mammography for women 50 to 79 years old, which yielded an MCYLS of $16,000. The method determined the least cost effective involved using annual mammography on high-risk women aged 40 to 79 years old with an MCYLS of $31,000. Screening methods that include women in their 40s also appear to be cost effective with an MCYLS of $20,000.

The impact of clinical history on mammographic interpretations
Article Abstract:
It may be better for radiologists to examine a mammogram first before reading about the woman's medical history. Researchers gave 10 radiologists mammograms from 100 women, of whom 64 had an abnormal mammogram and 18 had breast cancer. In one trial, the radiologists examined the mammogram without the history. In another, the radiologists read the patient's medical history first and then examined the mammogram. Knowledge of the history led many radiologists to change their interpretation. In some cases, they recommended fewer tests for women who had cancer and more tests for those who did not.
