Breast cancer and fat

Another story suggesting that eating too much fat causes breast cancer, based on another cobbled-together amalgamation of many other studies.

'The researchers found that women who ate high amounts of saturated fat were on average around 20 per cent more likely to develop breast cancer than women who ate low amounts. By comparison, women who ate large amounts of monounsaturated fats were around 10 per cent more likely to develop the disease. This figure is not deemed significant in scientific terms. Overall, women who ate large amounts of fats were 13 per cent more likely to develop breast cancer, a small but significant figure.'

No, it's not significant at all. There are so many potential errors in such a study, like matching subjects in different studies, different measurement methodologies etc., not to mention the usual problems of any single study, that only a very strong effect (at least a 100 per cent increase) could be safely regarded as meaningful.
