Mammography screening can reduce breast cancer mortality. A study published in the March issue of the International Journal of Cancer (Int J Cancer 2007; 120: 1076-1080.) suggests that mammogram screening Checking can reduce breast cancer mortality in women over the age of 40. Dr. Andrew Coldman of the British Columbia Cancer Center in Canada and colleagues examined the impact of breast X-ray screening on breast cancer mortality in women who volunteered to participate in the British Columbia Mammography Screening Program. They identified a female cohort who had undergone mammography screening at the age of 40 to 79 years between 1988 and 2003. All breast cancer cases and deaths that occurred in British Columbia came from the British Columbia Cancer Registry and were linked to the screening cohort. Female morbidity and survival rates not in this cohort were used to calculate the expected death of breast cancer in the cohort. The investigator adjusted the age and socioeconomic status of residents in this area at the time of diagnosis. Observed breast cancer deaths were excluded from expected breast cancer deaths and breast cancer mortality rates were calculated. A total of 598,690 women were included in the cohort. These women had a total of 2,196,441 mammograms, with an average of 3.7 screenings per woman. A total of 14,247 breast cancers were identified in the cohort during the study period. A total of 19,913 women in British Columbia who were not in the cohort were identified as invasive breast cancer. For all ages, the mortality rate was 0.60 (p < 0.0001). For women aged 40 to 49 years at the first screening, the mortality rate was 0.61, similar to that seen in women older than 50 years. Dr. Coldman explained that the mortality rate increased from 0.61 to 0.65 only in cases of age under 50, but it was still significant (p < 0.0001), indicating that the observed reduction in mortality was not due to this group of 50. Screening after age. The literature was used to correct the self-selection bias and increase the mortality rate for all ages to 0.76.
