More than 100 women die from breast cancer every day in the United States. The odds increase in postmenopausal women who have taken a combined estrogen and progestin hormone replacement therapy; these women also have an increased risk of developing progestin-accelerated breast tumors. Now, 色花堂 researchers have found that luteolin, a natural compound found in herbs such as thyme and parsley as well as vegetables such as celery and broccoli, could reduce the cancer risk for women who have taken hormone replacement therapy.
“In most circumstances, hormone replacement therapies improve the lives of menopausal women and achieve excellent results,” said Salman Hyder, the Zalk Endowed Professor in Tumor Angiogenesis and professor of biomedical sciences in the and the . “Nevertheless, research has proven that a higher incidence of breast cancer tumors can occur in women receiving therapies that involve a combination of the natural component estrogen and the synthetic progestin.
“Most older women normally have benign lesions in breast tissue,” Hyder said. “These lesions typically don’t form tumors until they receive the ‘trigger’— in this case, progestin—that attracts blood vessels to cells essentially feeding the lesions causing them to expand.” His newest study shows that when the supplement luteolin is administered to human breast cancer cells in the lab, benefits can be observed including the reduction of those vessels “feeding” the cancer cells causing cancer cell death.
