The research suggests that appealing to their strength as caretakers encourages them to take care of themsel...
Breast cancer is a significant global health issue, with most deaths occurring in low- and middle-income countries. A Personal View published in The Lancet Oncology suggests that population-based mammography screening is not practical or cost-effective in these countries.
A recent study found that radiologists who interpret a high volume of mammograms are better at detecting non-malignant lesions, resulting in lower false-positive rates. However, the number of cancers detected did not increase with volume, suggesting that a balance between screening and diagnostic mammogram interpretation is key.
The study found that radiologists who interpreted more mammograms had clinically and statistically significantly fewer false-positive findings without missing more cancers. Increasing annual screening volume requirements could lower the number of American women with false-positive workups by over 70,000 per year.
Women with prior breast cancer have lower sensitivity and specificity for detecting second cancers through mammography screening, which may lead to over- or under-diagnosis. Screening outcomes also depend on the treatment of the first cancer.
Women with a history of breast cancer have double the cancer rates as those without, according to a comprehensive study. Annual mammography screening detects second breast cancers early, but may not be as effective in detecting invasive breast cancer.
