ScienceDaily (Nov. 9, 2007) Researchers have discovered that a molecular switch in the protein making machinery of cells is linked to one of the most common forms of lethal breast cancer worldwide. The discovery by researchers at NYU School of Medicine could lead to new therapies for the cancer, called locally advanced breast cancer (LABC). Although precise data isn't available, LABC may account for 50 percent or more of breast cancers among women in developing countries, and 30 percent of breast cancers among socially disadvantaged and minority women in the United States. This type of cancer is defined by a large tumor that is about 2 inches or larger in diameter, about the size of a plum, when first diagnosed. The cancer may have spread into surrounding lymph nodes or other tissues. However, it hasn't yet spread to more distant areas in the body. Without treatment, fewer than 20 percent of patients with LABC are living five years after their diagnosis. Unfortunately, even with appropriate treatments, this cancer is deadlier than other types of breast cancer that are detected earlier. |
