Breast cancer is currently the leading cause of cancer-related death among women. However, according to studies, the risk of developing breast cancer can be reduced by following a healthy lifestyle, which includes a healthy diet that contains sufficient amount of fruits, vegetables and oily fish. Fish oil, according to researchers, can cut the risk of breast cancer by almost 14%.
Oily fish is a prominent source of the omega-3 fatty acids EPA and DHA. The anti-cancer property of oily fish is primarily attributed to these healthy fats. Oily fish are also one of the few dietary sources of vitamin D, which plays an important role in protecting women from breast cancer.
Here Is How Increasing Consumption Of Oily Fish Can Help In Lowering Your Chance Of Developing Breast Cancer:
Chronic low grade inflammation is a precursor to breast cancer. Although inflammation is a normal immune response of the body, prolonged inflammation damages the healthy cells and increases risk of mutation of the genetic materials of the cells. The anti-inflammatory property of the omega-3 fatty acids found in oily fish helps in suppressing production of the prostaglandins and other pro-inflammatory compounds. By reducing inflammation, oily fish helps in reducing risk of developing breast cancer.
Stops Proliferation of Breast Cancer Cells
Studies have shown that the omega-3 fats help in activating peroxisome proliferator-activated receptor (PPAR), which helps in blocking growth and multiplication of the breast cancer cells. Hence, adding omega-3 fatty acid rich fish to the daily diet helps in preventing cancer from spreading in the breast tissues.
Repairs Damaged DNA
Furthermore, omega-3 fats reduce the risk of developing breast cancer by supporting the natural ability of the body to repair the damaged breast cells. They support expression of BRCA1 and BRCA2, the two human tumor suppressor genes that are involved in repairing the damaged DNA. Mutation of BRCA1 and BRCA2 makes women vulnerable to breast cancer.
Triggers Breast Cancer Cell Death
Vitamin D found in fatty fish also plays an important role in preventing breast cancer. Studies have found a link between low vitamin D level and increased risk of breast cancer. Vitamin D binds to the vitamin D receptors in the breast tissues and triggers chemical signals that block growth of the breast cancer cells and help in destroying the cancer causing cells.
