LONDON -- A new study reopens the question, long dismissed by researchers, of whether women who eat high-fat diets increase their risk of breast cancer.
The study found that those who average more than 90 grams of fat a day have roughly double the risk of those who eat just 37 grams.
However, the finding is likely to be controversial, since it contradicts many large, careful studies that found no link between what women eat and their risk of this common cancer.
Researchers who conducted the latest study argue theirs is better, because it used a more precise method of measuring women's typical diets. However, others said the study is too small to overturn the vast research suggesting diet plays little or no role in breast cancer risk.
The study, published in this week's Lancet medical journal, was conducted at Cambridge University in England and involved 13,070 women who kept diet records from 1993-97.
