Overestimating Overdiagnosis in Breast Cancer Screening
Overdiagnosis in breast cancer has been a focus of increasing concern with wide ranges of calculations made indirectly through the study of prospective randomized trials and analyses of large registries. While most admit that some degree of overdiagnosis is inherent with ductal carcinoma in situ (DCIS), the rate of overdiagnosis with invasive disease is highly controversial. Although it is gene...
متن کاملEstimation of Overdiagnosis in Breast Cancer Screening
I. Summary The benefit of breast cancer (BC) screening with mammography has been demonstrated by randomized controlled trials (RCTs).

Thus, their detection and subsequent treatment is unnecessar...
متن کاملOverdiagnosis of breast cancer in population screening: does it make breast screening worthless?
The risk of breast cancer (BC) overdiagnosis attributed to mammography screening is an unresolved issue, complicated by heterogeneity in the methodology of quantifying its magnitude, and both political and scientific elements surrounding interpretation of the evidence on this phenomenon. Evidence from randomized trials and also from observational studies shows that mammography screening reduces...
متن کاملOverdiagnosis of breast cancer after 14 years of mammography screening.

Our study was criticised because we had only five years of follow-up time and did not take account of the fact that increased use of hormone replacement therapy could lead to more breast cancer. We have now been screening women for 14 years, and during a...
