Diet rich in fish oil 'reduces prostate cancer cell growth'

27 October 2011

A low-fat diet with lots of fish oils could slow the growth of prostate cancer cells, a study has found.

Researchers at UCLA's Jonsson Comprehensive Cancer Center found that a diet rich in fish oil supplements eaten for four to six weeks before prostate removal surgery slowed the growth and spread of cancer cells, making removal more successful.

According to the short-term study published in Cancer Prevention Research, men on a low-fat fish oil supplement diet were able to change the composition of their cell membranes in both the healthy cells and the cancer cells in the prostate.

Dr William Aronson, the study's first author and a researcher with UCLA's Cancer Center, said that the diet reduced the number of rapidly dividing cells in the prostate cancer tissue, which is important because the rate at which the cells are dividing can be used to predict future cancer progression.

Speaking at the Prostate Cancer Charity's National Prostate Cancer Research Conference in London, Professor Gail Risbridger explained that many treatments for prostate cancer focus on blocking the male sex hormone to slow down or even stop the disease from progressing.
