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.

Breast cancer screening guideline USPSTF - To the recommendation of the Expert Committee, the American Cancer Society, the American Association of Cancer (ACS), is continuing to perform breast cancer screening by mammography for the age of 40 and has voiced objections to the recommendations of the Expert Committee.

After that, a hearing was held in United States Congress on this recommendation, and the Secretary of Sebelius Health and Welfare said, "USPSTF is an external independent committee of the Government, and although it has shown new recommendations this time, it is not an institution that determines government policy We will not change the decision on whether to cover the United States government's mammography screening with insurance."

Compared to the prevalence of breast cancer by age, the United States is higher in women over 60 years of age compared to 40 to 50 years old, in Japan, since women aged 40 to 50 are more than 60 years of age, the recommendation of this United States Expert committee (mammography screening for the forties) is Japan It is considered to have a greater impact.

Breast cancer screening guideline USPSTF - Based on the results of the exchange of opinions with experts from the United States government agencies (NCI, CDC) in March this year, the views of the society are shown below.
  • 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.
