According to a study of more than 50,000 women in breast screening women, there is significantly more benefit than treatment without screening. Cancer.

This study, funded by the American Cancer Society and using data on women in Sweden, found that women who chose to participate in an organized breast cancer screening program were at 60% less risk of dying from breast cancer within 10 years of diagnosis. and there is a risk of death by 47% less than 20 years after diagnosis.

The study included 52,438 women aged 40-69 in Dalarna, Sweden, in the 39th year of the screening period (1977-2015). All patients received stage-specific treatment according to the latest national guidelines, regardless of their detection style.

The annual incidence of breast cancer was between 40-69 years of age, the incidence of lethal breast cancer at the age of 10, and mammography screening in women aged 40-69 years. year period (1977‐2015).

The results showed that women who chose to participate in an organized breast cancer screening program were 60% less likely to die from breast cancer within 10 years after diagnosis (relative risk, 0.40; 95% confidence interval, 0.34 ± 0.48) and 47 within 20 years of diagnosis. The risk of dying from breast cancer was lower (relative risk, 0.53; 95% confidence interval, 0.44 ± 0.63) compared with corresponding risks for non-participants.

Researchers said that this benefit is because the screening means they detect cancers at an earlier stage and that they respond better to treatment.

Professor Stephen Duffy, a senior author at the Queen Mary University in London, said: yazar Recent advances in treatments have reduced deaths from breast cancer. These new results, however, demonstrate the vital role that screening has to play, providing a greater benefit to women than modern treatments. We should ensure that participation in breast screening programs develops especially in socioeconomically deprived areas. "

In the United Kingdom, mammography screening for all women between the ages of 50-70 is presented by the NHS Breast Screening Program, with participation rates varying over 70% but dramatically across the country, with lower rates at lower rates in urban areas. it is.
