A study that looked into the molecular mechanisms of DHA against prostate cancer uncovered several methods by which DHA helps prevent, and even combat prostate cancer.

Changes in the healthy connective tissue that forms the prostate gland occur during prostate cancer.  These changes contribute to cancer’s spread, and are key factors that determine the severity of the problem.

One of these changes involves fibroblasts—the carpenter cells that naturally build prostate connective tissue. When cancer sets in, these fibroblasts are changed to a different version called myofibroblasts, which in turn fuel the growth of cancerous prostate tissue. Researchers found that DHA directly inhibits the conversion of normal fibroblasts into cancer promoting myofibroblasts.

Another important factor is the rate that new prostate cancer cells can infiltrate existing healthy prostate tissue.  This process is called invasiveness. The study found that DHA directly inhibits the invasiveness of cancerous prostate cells into healthy tissue.

Both of these issues are significant for prevention and as part of treatment for this issue.
