Interesting how data can be "spun" by researchers to say something else. Check this article from last week:

High Fat Diet May Contribute to Breast Cancer Risk

NEW YORK (Reuters Health) - The primary cause of breast cancer is still largely unknown. But the results of a new study indicate that a high fat diet by itself, while not likely to cause breast cancer, probably plays a supporting role.

The study findings are the latest round in a scientific debate about the link between breast cancer and dietary fat.

UK researcher Dr. Richard A. Wiseman, of the London School of Hygiene and Tropical Medicine, examined ``all relevant epidemiological and biological evidence'' pertaining to the development of breast cancer, in an effort to pinpoint a single cause responsible for the majority of cases.

The published data do not incriminate genes, the environment or infection as the main cause of breast cancer, Wiseman reports in the November issue of the Journal of Epidemiology and Community Health. Although estrogen is a promoter of breast cancer, according to the data, it is not the main cause of the disease.

``Dietary factors and especially fat consumption are associated with breast cancer,'' Wiseman concludes. ``However, the hypothesis that best fits the data is that dietary fat is not itself the causal agent but instead causes depletion of an essential agent that is normally protective against breast cancer.''

Wiseman further hypothesizes that a deficiency of this yet-to-be discovered agent, either by inadequate intake or depletion via a high-fat diet, working in tandem with age and estrogen, permits breast cancer to develop.

He speculates that the primary cause of breast cancer is a ''micro-nutrient or trace element present in soils,'' which then enters the food chain. ``Research into...micro-nutrients, trace elements, antibodies to infective agents and vitamins,'' should help identify the agent, he concludes. ``If such an agent is detected, then intervention studies with supplementation should lead to a decline in the incidence of breast cancer.''
