Women who participate in breast cancer screening have more than 50,000 studies showing that treatment benefits are much greater than women who are not screened. cancer.

The study was funded by the United Cancer Society and used data from Swedish women. Women who chose to participate in an organized breast cancer screening program had a 60% chance of dying from breast cancer within 10 years of diagnosis Within the next 20 years, the probability of dying from breast cancer was 47% lower.

The study included 52,438 women aged 40 to 69 years in Dalarna County, Sweden, during the 39-year-old screening period (1977 to 2015). All patients were treated according to the latest national guidelines regardless of detection method.

The annual incidence of breast cancer was calculated along with the annual incidence of those who participated in the mammogram or who did not participate at the age of 39 when the incidence of breast cancer among women aged 40 to 69 was fatal between 11 and 20 within 10 years . (1977-2015).

As a result, women who decided to participate in organized breast cancer screening programs were 60% less likely to die of breast cancer within 10 years of diagnosis (relative risk 0.40, 95% confidence interval, 0.34-0.48) Relatively low risk of death from breast cancer (relative risk 0.53, 95% confidence interval 0.44-0.63).

The researchers say these benefits arise because the screening test detects cancer early and has a much better therapeutic effect.

Professor Stephen Duffy, senior author of the Queen Mary University of London, said: "With recent improvements in treatment methods, mortality from breast cancer has declined, but these new results are important for screening "We need to ensure that participation in the breast screening program is improved, especially in socially and economically deprived areas."

In the UK, all women between the ages of 50 and 70 will undergo a mammogram with the NHS Breast Screening Program. Participation rates are above 70% on average, but they are dramatically lower across the country and lower in poor urban areas.
