title: Are mammography and palpation sufficient for breast cancer screening? A dissenting opinion.
abstract: Breast cancer is an equal opportunity killer in that as many as 60%-70% of breast cancer patients have no obvious risk factor(s). Thus, the continued reliance on the importance of risk factors to initiate screening programs may inhibit further inquiry into better diagnostic and prognostic indicators. An extensive review of past and recent literature reveals that mammography is not an objective examination. Its use as a screening tool is facilitated among women 40 years old and older whose breast tissue is primarily fatty and provides better visualization. Younger women are not generally advised to use mammography because of its potentially hazardous effects associated with repeated use of radiation. More importantly, regardless of patient age, radiologists interpret mammograms, and different degrees of interpretation error exist for different radiologists as well as for the same radiologist performing the analysis after a period of time. Thus, the use of mammography as the sole screening tool does not provide patients or physicians with a sense of confidence about sensitivity and specificity. Further, recent enthusiasm to promote mammography screening may give women unrealistic expectations, leading them to falsely believe that a negative examination is assurance that cancer is not present in its earliest detectable stage. We propose to supplement the physical examination and mammography with a third screening modality based on thermal detection monitors. This is a noninvasive and nonradiogenic tool and might enable clinicians to provide patients with every opportunity for early diagnosis.
