Validity, Reliability, and Sensitivity of MammogramsThe ability of the mammogram to detect breast cancer depends mainly on breast tissue density, tumor size, and radiology skills. Women greater than 50 years of age are more likely than those younger to reveal a tumor during mammography, due to the denser breast in the younger population (National Breast Cancer Foundation, 2016). The sensitivity of the mammogram is not only related to the dense breast but also those with fatty breasts (Komen, n.d.). Studies identified with sensitivity can pick up the slightest abnormal finding within the breast tissue, although no one test is 100 percent on specificity or sensitivity, it results in many cases not being missed, and some will mistakenly be diagnosed (Komen, n.d.). False positive
results can lead to patients with anxiety and further unnecessary testing (National Breast Cancer Institute, 2016). According to a study, there is a lack of validity of self-reports of mammography (Levine et al., 2019). Studies correctly identify about 87% of the female population that has breast cancer(Komen, n.d.). Specific tests may have fewer false-positive results; however, there can be an increase in missed cases (Komen, n.d.). There is a balance between specificity and sensitivity in the screening tests for both physical breast exams and mammography.
