Olive oil has long been known to have many health benefits. The great scholar Ibn al-Qayyim in his Prophetic Medicine promoted some of its benefits, and more recently many studies have shown its benefits for fighting cancer, heart disease, and an olive oil-rich diet has been linked to long, healthy and happy lives.
Researchers investigated the effects of this growth factor with extracts from commercial extra virgin olive oil in cultured human breast cancer cell lines. They tested for the ability to kill both HER-2 positive and negative tumors.
The lead researcher, Javier Menendez said, "Our findings reveal for the first time that all the major complex phenols present in extra-virgin olive oil drastically suppress overexpression of the cancer gene HER2 in human breast cancer cells".
They found that the main extra virgin olive oil polyphenols had strong tumor killing effects by selectively triggering high levels of apoptotic cell death (programmed cell death). The study concluded that extra virgin olive oil is an excellent and safe treatment targeting HER-2.

Types of Olive Oil
All types of olive oil are sources of monounsaturated fat, but extra virgin olive oil, the oil that comes from the first pressing of the olives, contains higher levels of antioxidants, particularly polyphenols and Vitamin E, because it is less processed.
