A diet rich in a fat found in oily fish and some seeds may
protect men with prostate cancer from developing a more
aggressive form, scientists have found. Oily fish contains
omega-3 fats Prostate cancer is much more likely to be life-
threatening if tumour cells migrate and invade other tissues,
such as the bone marrow. Lab tests found omega-3 oil - present
in fish like salmon - prevented this. The results of the study,
based at Manchester's Christie Hospital, are in the British
Journal of Cancer. The Paterson Institute researchers tested the
effect of two types of dietary fat on prostate cancer cells in
the lab. Previous research has suggested omega-3 fats, which is
also found in some plant sources such as pumpkin seeds, may help
cut the risk of cancer - and other conditions, such as heart
disease. Omega-6 fats, found in vegetable oils, nuts and seeds,
also play a key role in keeping us healthy. However, while
omega-6 fats increased the spread of prostate cancer cells into
bone marrow, omega-3 fats blocked th
