Lower Breast Cancer Events in Survivors with Higher Omega-3 fish oil Consumption- specifically EPA

Links between the chance of developing breast cancer and the consumption of fat or individual fatty acids have been around for years, but the research findings have been all over the map. Animal and cell culture studies have often reported links between omega-3 fatty acids from seafood and lower growth and spread of breast cancer tumors, but these findings have not consistently carried over into human studies. Nevertheless, the topic continues to be investigated. A systematic review of the scientific literature a few years ago analyzed 10 studies in humans and concluded there was about a 30% lower risk of breast cancer in women with higher intakes of seafood omega-3s.

Investigators in California asked a different question about the possible links between fish or omega-3 consumption and breast cancer. They focused on breast cancer survivors. The researchers asked whether omega-3 intakes affect a woman’s disease-free survival or subsequent breast cancer events after she has been treated for early-stage breast cancer. Participants in the study were enrolled in the Women’s Healthy Eating and Living Study, which was designed to learn whether eating more vegetables, fruits and fiber affected the risk of recurrent or new primary breast cancer. The study included women from the ages of 18 to 70 who were monitored over a 7-year period.

Food intake information was obtained when the women entered the study. The women were assessed for their health outcomes and the development of any cancer at intervals from 1 to 6 years after the study began. At the beginning of the study, the women consumed an average of 186 mg per day of the long-chain omega-3s found in seafood. This is nearly double the amount consumed by the general population.

After 6 years, their intake had increased to 237 mg per day, an increase of 27%. This change was unrelated to the study. Women’s use of fish oil supplements also increased during that time from 4% to 10% of women. The investigators found that the increase in omega-3s was significant for women who did not experience additional breast cancer events, but not among those who had additional events. An “event” was considered to be a recurrent cancer or a new invasive breast cancer.
The key finding was that women in the upper two-thirds of long-chain omega-3 intakes experienced a 25% reduction in the likelihood of developing an additional breast cancer event. Higher omega-3 intakes ranged from a median of 73 to 365 mg per day. It made no difference whether the omega-3s came only from food or from food plus supplements. The investigators also noted that women in the highest third of omega-3 consumption were 40% less likely to die from breast cancer compared with women in the lowest third of omega-3 consumption. The cutoff for the highest omega-3 intake was 153 mg/day or more.
