Fatty fish lowers kidney cancer risk in women

Study findings published in the Journal of the American Medical Association report that consumption of fatty fish can help prevent the most common form of kidney cancer in women.

More than 80 percent of all kidney cancers are accounted for by renal cell carcinoma (RCC). Age, sex, obesity, smoking and several genetic factors are all believed to be risk factors.

Researchers drew upon data gathered during the Swedish Mammography Cohort Study, which took place between March 1987 and December 1990. Of the 90,303 women who took part, 66,651 returned completed food frequency questionnaires at baseline.

A second questionnaire was sent out to the 56,030 participants who were still alive and residing in the area in September 1997, 39,664 of whom responded.

Researchers observed that those who consumed one or more serving of fatty fish each week seemed to have a 44 per cent decreased risk of RCC compared with those who consumed none at all.

Moreover, those who reported long-term consumption between baseline and the 10-year follow-up had a 74 per cent lower risk.

By contrast, no association was seen between lean fish and other seafood consumption and RCC incidence.
