Prostate Cancer :: Diet rich in fish reduce spread of prostate cancer

Eating foods such as fish that are rich in omega 3 fats might help prevent the spread of prostate cancer to other parts of the body, according to research published in the British Journal of Cancer last week.

Omega 3 fats are found in so-called ?oily? fish such as salmon, mackerel and fresh tuna. It has previously been claimed that they have protective effects against cancer. This research, though still at an early stage, suggests that a diet rich in particular omega 3 fats might protect men with prostate cancer from developing a more aggressive form of the disease.

There are two main groups of polyunsaturated fatty acids found in our diet ? omega 3 and omega 6. Both types have essential roles in keeping us healthy but the Manchester research shows they have very different effects on prostate cancer cells.

Dr Mick Brown from the Paterson Institute, chief scientist in the research group, said: ?Omega 6 fats, found in vegetable oils, nuts and seeds, increased the spread of tumour cells into bone marrow. This invasion was blocked by omega 3 fats ? the ones found in oily fish. 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.?
