Omega-3 Fatty Acids in Oily Fish like Salmon could block Prostate Cancer

Omega-3 oil present in fish like salmon could block prostate cancer, scientists have found.
Prostate cancer is a disease in which cancer develops in the prostate, a gland in the male reproductive system. It may also spread from the prostate to other parts of the body, especially the bones and lymph nodes.
People in this disease suffer pain, difficulty in urinating and erectile dysfunction.
The disease only occurs in men and develops most frequently in individuals over 50 years old. It is the second most common type of cancer in men and it is responsible for more deaths than any other cancer except lung cancer.
Previous research suggested that omega-3 fats, which are also found in mackerel and fresh tuna, may help cut the risk of cancer and heart disease.
The Paterson Institute researchers at Manchester's Christie Hospital have now found that 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.
Omega-6 fats, found in vegetable oils, nuts and seeds, 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 this, the researchers 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," researcher Mick Brown said.
