Omega-3s improve energy in cancer survivors
Many people treated for cancer have lingering fatigue after therapy ends, which may be aggravated by chronic inflammation, doctors said. Omega-3s have reduced inflammation in healthy people, leading doctors to examine its effect in breast cancer survivors.

In one study, doctors measured the diets of 633 survivors with stage I to stage IIIA breast cancer, and followed up 39 months after diagnosis. Overall, 42 percent complained of being chronically fatigued three years after diagnosis. Women with the highest levels of C-reactive protein (CRP), a sign of inflammation, were nearly twice as likely to be fatigued as women with low CRP levels.

When doctors looked at the ratio of omega-3s to omega-6s in the diet, women who got the most omega-3s compared to omega-6s were half as likely to be chronically fatigued as women who got the least omega-3s.
