Background: A recent guideline by the American Cancer Society recommended that mammography (MMG) should be done for women starting in their mid-40s. In Thailand, information on opportunistic mammography screening is limited and data on the total incidence of breast cancer are also lacking. The purpose of this study was to estimate the breast cancer detection, incident and prevalence rates among Thai women. Materials and Methods: We retrospectively reviewed the opportunistic mammography screening of normal women between 30 and 80 years who underwent the procedure between 2001 and 2010. All cases were followed until 2012. The detection rate was calculated for the whole period of observation using 'number of women with positive findings' divided by 'total number of women screened'. The incidence rate was calculated only at the first MMG while the subsequence rate was calculated based on all new cases detected at each subsequent MMG. Results: Among the 47,430 women, there were 152,091 MMGs or approximately 3.2 occasions per person (range, 1-10). The average duration of the interval between each subsequence visit was 1.8 years. Overall, breast cancer was detected in 543 women, with a detection rate of 10.3 per 1,000 persons. The prevalence rate of breast cancer at the first visit was 5.78 per 1,000 persons. The incidence or new cases detected at any follow-up visit was 10.4 per 1,000 persons. The overall interval cancer was 0.91 per 1,000 women, mainly detected before their second and third MMG, with a rate of 0.0.47 and 0.76 per 1,000 women. Conclusions: Opportunistic mammography screening in Thailand detected 10 case of breast cancer from each 1,000 women. This paper indicated a high rate of cancer detection during a two year interval, hence, a screening mammogram should be performed more often.
