A massive study related to mammogram followed around 100,000 sewdish women for 29 years. Many doctors believe that this study will put the recent furore over breast cancer screening to rest.

Study has revealed that mammograms for 7 years reduce breast cancer deaths by approximately 30 percent compared to women who didn’t take mammograms.

“I think this study indicates the absolute benefit of screening in terms of breast cancer deaths prevented,” says Stephen Duffy, a professor of cancer screening at Queen Mary, University of London, and lead author of the study.

The Swedish study promulgated in Journal Radiology has suggested that mammograms can save many more lives. But regarding breast cancer, long term consideration is important because many types of breast cancer take many years to become fatal and dangerous.

Latest study included around 100,000 women from two countries in Sweden. Started in 1977, researchers made half of the women to receive regular medical attention for 7 years and other half were given regular mammograms. After the end of 7 years, researchers did a follow up for 22 years.It was found that with passing years; effect of mammograms became more apparent. After 10 years of the study, 71 lives were saved; after 29 years 158 lives were saved , said Duffy, study leader.
