Experts hailed the findings, which examined over 2,400 women with breast cancer over a ten-year recovery period, as “extraordinarily important”.
The study found that women who lost a small amount of weight, roughly five to six pounds, were 70 per cent more likely to survive some of the deadliest formers of breast cancer.
Scientists believe the findings, presented earlier this month at the San Antonio Breast Cancer Symposium, mean that diet could have as large an effect on a patient’s outcome as a breakthrough drug or radical chemotherapy.
The Women’s Intervention Nutrition Study tracked the women for two decades after they received brast cancer treatment to see if changes in their diets affected the diseases reoccurrence.
Half of the women were placed on a low-fat diet, with those who lost weight and maintained that weight loss for five years showing lower death rates.
One theory is that weight loss also reduces levels of glucose and insulin that would otherwise ‘feed’ cancer cells.
The most significant differences were among the 20 per cent of women whose cancer was not linked to hormones. Previous research has indicated that overweight women are more likely to develop breast cancer, as well as being more resistant to attempts to treat it.
Scientists believe this resistance may be linked to lower levels of oestrogen, which is known to trigger cancer.
Professor Tony Howell, director of research at the Genesis breast cancer prevention charity, told the Daily Telegraph the new findings were an “extraordinarily important result”.
“A 69 per cent reduction in deaths in a group with few alternative treatments – that’s as good as any drug,” he said.
“For 20 per cent of women, this is as effective as chemotherapy.”
Despite the promise of the results researchers cannot be sure they are not an anomaly, due to the relatively small sample size, but as further tests are commissioned scientists are optimistic about the effect future results may have on cancer treatments.
