(Then, the recommended representation is "to consider the value judgments of the interests and disadvantages of each individual subject to a regular mammography screening under the age of 50", but the decision of recommended grade C has not changed.)
As a reason why the recommended grade was changed from B to C, the benefit of mammography screening (decrease in breast cancer mortality) is also recognized for women in their forties, but the disadvantages (results of There is an unnecessary examination for the person who was not cancer and treatment for cancer which does not become a clinical problem even if neglected, etc.), compared to women over the age of 50 in the case of profit and disadvantage, it is mentioned that profit is less than the disadvantage in the Forties.

- This revision of USPSTF is generally appropriate based on scientific evidence, but it is based on American data and cannot be applied as it is Japan.
- Our country's recommendations should be revised based on our country's data, but our country's own data on the disadvantages is scarce, and we need to collect this as soon as possible.
- The effects of the death loss it is not a comparison of the person who did not receive the ① checkup actually, the point of underestimating the death reduction effect because it is a comparison of the person who was assigned to the examination group in the evaluation study and the control group. It is necessary to consider the possibility of underestimating the mortality effect of the short 40-year-old age of observation because it has not adjusted the ② observation years.
- It is reasonable for the time being to continue the current recommendation until the revision of the recommendation based on the scientific basis in Japan.
- The Society is committed to the accumulation of scientific knowledge about not only profits but also the disadvantages of breast cancer screening, and we would like to continue to make an effort for the public to perform better breast cancer screening.
