Taking supplements with omega 3 fatty acids, derived from fish oils, may increase the risk of prostate cancer high grade in more than 70% in men, according to a study Fred Hutchinson Oncology Research Center in Seattle, United States.

Regarding the mechanism by which the formation of cancer cells can be triggered and the way to compromise the immune system, the study does not show anything conclusive, therefore, it is necessary to carry out more investigations that confirm this possible relationship with the prostate cancer , according to experts from the Cancer Research UK and Prostate Cancer UK centers.
