Extra Virgin Olive Oil may be able to Prevent Aggressive Triple-negative Breast Cancer

According to an article that appeared in Olive Oil Times, January 30, 2019, researchers at the University of Jaén in Spain discovered that a minor compound, hydroxytyrosol (HT) found in extra virgin olive oil (EVOO) may be able to prevent an aggressive deadly type of breast cancer. This rare deadly type of breast cancer is known as triple-negative breast cancer. The results of this research were published November 21, 2018, in the European Journal of Nutrition.

Results of the Study

In the lab (in-vitro) the compound hydroxytyrosol (HT) was able to prevent the growth of triple-negative breast cancer stem cells and also to prevent tumor cell migration which causes metastatic new tumors.

This experiment was successful in that hydroxytyrosol was found to be chemopreventive against aggressive triple-negative breast cancer cells and kept them from multiplying in the lab.

Even though this hydroxytyrosol compound found in extra-virgin-olive oil may prove to be able to successfully treat triple-negative breast cancer in humans, more research is needed.

Human Clinical Trial

A human clinical trial is taking place at Houston Methodist Cancer Center to test hydroxytyrosol on high-risk patients. Also, the results of this study may be used to test hydroxytyrosol on animal models.

Triple-Negative Breast Cancer

According to the Centers for Disease Control and Prevention (CDC), Triple-negative breast cancer is a very aggressive type of cancer with a low survival rate. It does not have any receptors that are commonly found in other kinds of breast cancer, so doctors have fewer options for treatment. Certain ethnic groups like Ashkenazi Jews have a high genetic risk for this kind of breast cancer. Treatment is usually by chemotherapy, but there is also a new kind of immunotherapy-chemotherapy treatment that has been approved by the Food and Drug Administration (FDA). Unfortunately, according to the National Cancer Institute (NCI), triple-negative breast cancer commonly returns after treatment and then it is very difficult to treat.

Breast Cancer in the United States

According to the Centers for Disease Control and Prevention (CDC), except for skin cancer, breast cancer is the most common cancer in women and is the second most common cause of death from cancer in women.
Every year about 237,000 new cases of breast cancer are diagnosed in women and about 2,100 in men. About 41,000 women and 450 men in the United States die every year from breast cancer.

Age Increases Risk for Breast Cancer

Women usually get breast cancer around the age of 61. Men usually get breast cancer when they are from 60-70 years old.

Other Studies Linked to Preventing Breast Cancer

See our blog post from September 20, 2018, about research that shows that high levels of Vitamin D may lower the risk for developing breast cancer.

A study published October 16, 2018 in Clinical and Experimental Metastasis by researchers at the University of Nebraska Medical Center shows that omega-3 polyunsaturated fatty acids (PUFAs) found in oily fish may lower the risk for breast cancer.
