The Claim
Daily supplementation with 1 gram of marine omega-3 fatty acids (460 mg EPA and 380 mg DHA) for a median of 5.3 years does not significantly reduce the incidence of invasive cancer of any type in healthy adults aged 50 and older, based on a hazard ratio of 1.03 (95% CI: 0.93–1.13; p=0.56) from a large randomized trial involving 25,871 participants.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking a daily omega-3 supplement for over five years doesn't seem to lower the risk of getting any kind of invasive cancer in healthy people over 50, according to a big study.

1 studyStudy: Marine Omega-3 Fatty Acids and Prevention of Vascular Disease and Cancer
This big study gave thousands of older adults fish oil pills every day for over five years and found they didn’t get less cancer than people who took dummy pills. So, fish oil doesn’t seem to help prevent cancer in healthy older people.
