The natural extract from rose hip can prevent and slow the growth of triple-negative breast cancer, one of the most aggressive forms of the disease, and one that is not responding to chemotherapy.
A 1 mg dose of rosehip extract has reduced the growth of triple-negative cancer cells by 50 per cent and limited its spread by up to 45 per cent, researchers from North Carolina Agricultural and Technical State University have discovered in major breakthrough research.
They exposed cancer cell lines to various strengths of rosehip extract, and the effect lessened with decreasing concentrations. The extract also appears to make the chemotherapy drug, doxorubicin, more effective.
The next stage for the researchers is animal studies, with the hope that rosehip will be recommended as a preventative of breast cancer as well as a treatment, especially for triple-negative cancer.
Triple-negative breast cancer mainly affects young women and non-whites and Hispanics. It does not respond to chemotherapy because the cells do not have the normal growth-factor receptors that chemotherapy targets.
