For 31 years up to December 2003, we had been conducting breast cancer mass screening by physical examination including inspection and palpation, and then in 2004 we started a new trial using mammography. The new screening method was carried out in two different ways. In Method A, the screening consisted of two-projection mammography without physical examination and the participant's self-palpation. In Method B, an individual participant took a screening examination at an institution which fulfilled the requirements stipulated by the Ministry of Health, Labour and Welfare in terms of equipment, staff, and the types of examination available. Screening with Method B was available only in Kochi city. Method A screening was available in the other 52 districts of Kochi Prefecture, including cities, towns and villages. In Method A, 14, 478 women participated in the screening during a 9-month period from April through December, 2004, with a recall rate of 9.0% (1, 307 women), and a breast cancer detection rate of 0.31% (45 women). In Method B, 1, 216 women were screened during a 3-month period from October through December, 2004, with a recall rate of 11.4% (139 women) and a breast cancer detection rate of 0.41% (5 women). When we compared the cancer detection rate between the two groups, it appeared that slightly less than 10% of breast cancers were not detected by mammography in Method A.<BR>In the future, we hope to reduce the incidence of false negative mammogram readings, and to determine whether Method A is a truly satisfactory screening approach.
