Role of molecular clocks in tumor growth

Just as no two people possess the same genetic makeup, a recent study has shown that no two single tumor cells in breast cancer patients have an identical genome. In fact, depending on the tumor cell, they grow at dramatically different speeds, according to a study led by Nicholas Navin, Ph.D., assistant professor in the Department of Genetics at The University of Texas M.D. Anderson Cancer Center in Houston. The study findings may have important implications for the diagnosis and treatment of breast cancer. Read more here.
