Abstract
Mammographic screening for breast cancer was performed in Tokushima prefecture from 1995 to 2000. Of 17, 956 screenees examined, 53 were diagnosed as having breast cancer (recall rate 6.8%). The detection rate and sensitivity in all women and in those aged 50 and over were significantly different from those for physical examination alone. The detection rate and sensivitity in women aged 49 and under were 0.19% and 84.6%, respectively. These results were better than those for physical examination alone, although the difference was not significant. All the breast cancers detected in those aged 49 and under were early cancers.
These results suggest that mammographic screening may be effective for women aged 49 and under in Japan.
