Eat more fish to stop prostate cancer growing

Men whose prostate cancer is in its early phase should start taking omega 3 supplements and eating more fish—it can stop the cancer cells growing.

At the same time, they should be cutting back on the omega-6 fats, which are found in processed foods such as chips, cookies, and fried food.

The combined effect can slow, or even reverse, the growth of prostate cancer cells, say researchers from the University of California’s Los Angeles Health Sciences.

In a test on 100 men with early-stage prostate cancer—who all opted for ‘active surveillance’, where the progress of the cancer is regularly monitored before deciding on next steps—those who followed the omega-3 diet saw their cancer markers drop by 15 percent, while markers for those who followed their usual diet rose by 24 percent.

The dietary change could be enough to not only slow the cancer’s growth but also delay or even prevent aggressive treatment, said William Aronson, the lead researcher.

The approach is ideal for men who have chosen active surveillance of their cancer.  Usually, around half of all men who opt for this end up having surgery or radiation within five years, but that ratio could be reduced if they adopt a high omega-3 and low omega-6 diet, he added.
