Women who are involved in breast screening significantly have a significant benefit of treatments than those that are not screened, according to a study * of more than 50,000 women announced in Cancer.

The study, funded by the American Cancer Association and data used on women in Sweden, found that women who chose to take part in a systematic breast cancer screening program were 60% less death of breast cancer within 10 years after diagnosis, and 47% of lower risk of breast cancer died within 20 years of diagnosis.

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

The annual breast cancer cases combined with the annual causes of cancerous cancer cancers were reported within 10 and within 11 to 20 years of diagnosis among women aged 40 to 69 who were either taken part in mammography screening during the 39-year period (1977-2015).

The results showed that women who chose to take part in a systematic breast cancer screening program had 60% less death of breast cancer within 10 years of diagnosis (relative risk, 0.40; 95% confidence interval, 0.34-0.48 ) and 47% lower risk of breast cancer within 20 years of diagnosis (relative risk, 0.53; 95% confidence interval, 0.44-0.63) compared to the corresponding risks to people who do not participate.

The researchers said that this benefit was due to screening and cancer finding earlier, making them responding better to treatment.

Senior author Stephen Duffy, of Queen Mary, University of London, said: "Recent improvements in treatments have led to fewer deaths from breast cancer, however, these new outcomes show the role It is essential that screening must also be played, giving women more benefits of modern treatments. We need to ensure that participation in breast screening programs improves, especially in disadvantaged areas economically- social. "

In the UK, mammography screening is offered to all women aged 50 to 70 through the NHS Breast Screening Program, with participation rates averaging more than 70% but varied dramatically across the country, with lower rates in poorer city cities.
