Fish oil study: Only relationship between cancer, Omega-3 in question, not risk, A fish oil study that appears to reveal that too much of the Omega-3 fatty acids found in fish oil could be linked to prostate cancer in men may be misleading, Examine Health reported this Thursday, July 11. While a connection between Omega-3 in the fish oil study and those men with cancer may indeed exist, only the relationship between these two is brought into question, rather than a direct link of fish oils “causing” cancer.
The fish oil study revealed in its recent findings that some men are up to 71% more likely to develop aggressive cancerous tumors and prostate cancer when they had significantly higher levels of fish oils in their system — namely, Omega-3 fatty acids.
However, Examine Health reveals that the temporal relationship is what needs to be focused on in this fish oil study, rather than a direct link between fatty acids and prostate cancer. According to the report:
“The temporal aspect is important, since fish oil supplementation can drastically change serum levels of omega-3s in the blood. It is quite common for people diagnosed with prostate cancer to supplement with fish oil, as it is commonly touted to be cancer-protective (which would mean that prostate cancer precedes fish oil supplementation). A previous study using persons from SELECT using a design that could assess this temporal relationship found no relation (either protective or harmful) with prostate cancer incidence.”
Finally, the fish oils study in question failed to measure the notion of mortality, concluded the report. While fish oils may not necessarily reduce the risk of prostate cancer or eventual death, that doesn’t necessarily mean they are a major contributing factor either.
Even so, while this fish oil study cannot prove that too many fish oils could lead to cancer, a relationship or link between too many Omega-3 levels in the body and cancer may exist, so men are encouraged to think before popping too many supplemental pills.
