Dangerous 'Two-Faced' Protein Crucial To Breast Cancer Spread And Growth Identified B
 

Two critical properties of cancer cells are their ability to divide without restraint and to spread away from the primary tumor to establish new tumor sites. Now, researchers from the Mayo Clinic campus in Florida have found a protein they say acts as a deadly master switch, both freeing cancer cells from a tumor while ramping up new growth.
