Researchers have shown that combining blueberry extract with radiation may be the next treatment in the war against cervical cancer. Plus, Blueberry extract also offered normal cell protection from the radiation at the same time
Worldwide, cervical cancer is the third most common cancer among women and the second most frequent cause of cancer-related death, accounting for nearly 300,000 deaths annually. In developing nations, it is often the most common cause of cancer-related death among women and a leading cause of death overall.
One of the most common treatments for cervical cancer is radiation. While radiation therapy destroys cancer cells, it also destroys nearby healthy cells. University of Missouri School of Medicine researchers studied in vitro human cancer cells to show that combining blueberry extract with radiation can increase the treatment’s effectiveness.
When Radiation therapy is needed it uses high-energy X-rays and other particles such as gamma rays to destroy cancer cells. For some cancers, such as late-stage cervical cancer, radiation is a good treatment option. However, collateral damage to healthy cells always occurs. Because of the damage to healthy cells researchers studied blueberry extract to verify if it could be used as a radiosensitizer.
Radiosensitizers are non-toxic chemicals that make cancer cells more responsive to radiation therapy. In a previous studies research has shown that resveratrol, a compound in red grapes, could be used as a radiosensitizer for treating prostate cancer. It is also know that Blueberries also contain resveratrol. In addition to resveratrol, blueberries also contain flavonoids, which are chemicals that may have antioxidant, anti-inflammatory and antibacterial properties.
The researchers used human cervical cancer cell lines to mimic clinical treatment. The cell lines were divided into four groups that included a control group, a group that received only radiation, a group that received only blueberry extract, and a group that received both radiation and the extract.
Researcher found that on its own, radiation decreased cancer cells by approximately 20 percent. Interestingly, the cell group that received only blueberry extract had a 25 percent decrease in cancer. However, the biggest decline in cancer cells occurred when the radiation was combined with the blueberry extract. There was a 70 percent decrease in cancer cells in the group the blueberry and radiation group.
The other interesting observation was that the blueberry extract also reduced the abnormal explosion of cell growth, which is what cancer is. While the blueberry extract inhibits the birth of cancer cells it also tricks the cancer cells into dying. So the extract inhibits the borth and promotes the death of cancer cells.
Blueberries are an amazing food source with antioxidant properties and many health benefits. They are also found all over the world and it is great to see this super food doing a super job of boosting the effectiveness of existing medical therapies to save women’s lives around world.
