Recent research has suggested that having a yearly mammogram "greatly reduces the risk" of mastectomy following incidences of breast cancer in women.
Presented at the annual meeting of the Radiological Society of North America, the study showed that regular screening had demonstrable benefits.
A total of 19 per cent of women aged between 40 and 50 who had been screened for breast cancer in the previous year required a mastectomy after diagnosis.
This is significantly less than the 46 per cent of women who had not been screened in the previous year, suggesting that regular screening has a clear health advantage.
However, Dr Marilyn Glenville, a nutritionist specialising in women's health, said that other studies have shown that "mammograms can trigger cancer and increase the risk by more than 50 per cent if the woman already has a family history risk of breast cancer".
Breast cancer is the most common cancer in the UK and in 2007 alone almost 45,700 women were diagnosed with the disease.
