Breast cancer screening has come under criticism for unnecessarily sending women for surgery for cancer.
However, a new study conducted by scientists at the Wolfson Institute of Preventive Medicine in Barts and the London School of Medicine and Dentistry, has found that the positive results of screenings outweigh any negatives.
According to the research, for every one woman that is 'over diagnosed' with the cancer, another two women's lives are saved.
Dr Stephen Duffy, lead author on the study, commented: "Unfortunately, we haven't yet got a flawless screening test, and some cases that are picked up wouldn't have needed treatment.
"But for every case like this, screening saves two women who would have otherwise died from breast cancer."
The news comes as a further study has re-examined the close link between breast cancer and lifestyle choices.
According to the research from Queen's University Belfast, consuming large amounts of alcohol can increase the chance of developing breast cancer by 21 per cent.
