The authors would like to draw the reader’s attention to errors in the following article:

Lee et al. “Cost-effective mammography screening in Korea: High incidence of breast cancer in young women”. Cancer Sci 2009; 100: 1105–11.

The authors would like to correct the following statements in the introduction on page 1105 which may cause confusion.

“It was also reported that a screening plan for women in their 40 s or for women older than 65 years might be most cost-effective.” should be corrected to:

“There are still debates on whether women in their 40 s can have benefits from mammography screening as compared to women over 50 years of age whose risks from mammography overweigh the benefits from it.(5) Others reviewed publications between January 1989 and March 2002 and had concluded that biennial breast cancer screening after age 65 can contribute to the reduction of mortality at reasonable costs for healthy women.(6)

“The consensus regarding a mammography screening plan in Western countries is to perform it annually or every 2 or 3 years for women who are at least 40 years old.” should be corrected to:

“The American Cancer Society and other organizations in their guidelines recommended for American women to start mammography screening annually or every 2 or 3 years from at least 40 years of age.”

The reference the authors quoted was the review article on the recommendation on cancer, including breast cancer, by the American Cancer Society (ACS) and other organizations. The ACS recommended starting annual mammography screening for women from at least 40 years of age. Other organizations also recommended similarly.

Although in Western countries, women over 50 years of age can benefit from mammography screening, in Korea, the incidence rate is the highest for women in their 40 s and the number of breast cancer victims are on the rise. Current mammography screening is based on the recommendations coming from the West. There have also been concerns and worries on the increasing medical care costs as well as the screening intervals for Korean women. One of the purposes for our study was to provide the evidence to give a guideline for the breast cancer screening starting age and intervals, and to examine the cost-effectiveness of the possible screening intervals.

The authors apologize for any confusion they may have caused.
