説明
In Japan the breast cancer screening for women of age over 40 years started at last from 2004 using mammography with physical examination of 2 year interval. However its attendance rate is very low so that the screening cannot affect the mortality for breast cancer. On the other hand, the attendance rate for breast cancer screening is shown to be over 70% in Western countries and its effect on breast cancer mortality is clearly seen. <BR>In this study, reduction of the breast cancer mortality is predicted when the attendance rate of mammographic screening of 2 year interval is over 50% for 40-84 years old Japanese women in the year 2025. At first the incidence of breast cancer in 2025 are estimated by multiplying the population of Japanese women in 2025 and breast cancer incidence rate of age group of 5 year in 1998. Number of incidence is 38, 037 women for all age and 32, 967 women for 40-84 years old. If breast cancer screening is not performed in 2025, number of breast cancer deaths is estimated to be 11, 411 women for all age assuming mortality rate of 30%. However if mammographic screening of 2 year interval is practiced to 50% of women of 40-84 years old in 2025, number of breast cancer deaths is expected to be 9, 375 women. Thus we can obtain that Relative Risk is 0.82 and Risk Difference is 2, 036 women. Japanese Government sets a goal for the attendance rate of cancer screening to be 50%. If we can attain this objective, mortality of breast cancer of Japanese women can be reduced by 18% in 2025.
