Protein May Be Key to Cancer's Deadly Resurgences

March 3, 2015 4:29 pm | by Pete Farley, University of California San Francisco | Comments

Tumor recurrence following a period of remission is the main cause of death in cancer. The ability of cancer cells to remain dormant during and following therapy, only to be reactivated at a later time, frequently with greater aggressiveness, is one of the least-understood aspects of the disease.
