A discovery made by a University of Minnesota scientist may give women diagnosed with breast or ovarian cancer a greater chance for long-term survival. Dr. Timothy Hallstrom, in collaboration with his former colleagues at Duke University, has found how key genes cause the breast and ovarian cancer cells to either multiply or die. The scientists have spent 7 years working on this project; their recently released data is based on tissue samples taken from 408 women diagnosed with breast cancer and 153 women diagnosed with ovarian cancer. Hallstrom says cancer begins in pathways in the body that become extremely active through mutations. The new research, he explained, shows that certain pathways converge to block target genes from causing the cancer cells to die. Hallstrom presented his research to the highly reputable journal "Cancer Cell" last summer, after performing a few more necessary experiments, his findings were released Tuesday morning.
