According to researchers from Britain, women who are under the age of 50 and have a considerable family history of breast cancer appear to benefit greatly after going through the screening process, mammography.

Stephen Duffy, BSc, MSc, of Queen Mary University in London along with colleagues said that due to the screening program held by the annual screening program among 6,170 women five deaths were prevented and these women were followed up for four years and were all in the same age group.

The estimates of the figures were done from the historical data from similar populations of women who didn't undergo a routine screening. The ratio is screenings required to prevent a death is 5,000 to one as per the researchers indications online in Lancet Oncology.

Duffy and colleagues wrote. "Our results provide some confidence in the interim that the surveillance strategy is effective." She also said that the National Health Service wanted to offer a screening mammography to younger women along with observing a `quantitative assessment' which didn't need a random trial.
