Eating Oily Fish Cuts Spread of Prostate Cancer

Eating oily fish and other foods rich in omega-3 fatty acids may help reduce the spread of early prostate cancer, according to new studies from Britain.

Dr Mick Brown, chief scientist at the Paterson Institute in Manchester, England said the studies strongly suggest that a diet rich in omega-3 fatty acids might help to inhibit the spread of the disease in men with early prostate cancer.

"Omega-6 fats, found in vegetable oils, nuts and seeds, increased the spread of tumor cells into bone marrow. This invasion was blocked by omega 3 fats - the ones found in oily fish," Dr. Brown said.

"It is possible to have a healthy balance of these two types of fat - we only need about half as much omega-3 as omega-6 - that will still stop cancer cells from spreading," he added.

The researchers believe omega-3 fatty acids interfere with functions of omega-6, which may be used as a source of energy by cancer cells.

"Eating a diet with the right balance of omega 3 and omega 6 fats may well help to keep prostate cancer within the prostate gland where it may be monitored safely or more easily treated with surgery or radiotherapy," said study co-author Dr. Noel Clarke.

The study appeared in the British Journal of Cancer
