Cancer Cells Force Normal Cells to Mimic Viruses to Help Tumors Spread, Resist Treatment

on .

In a study that could explain why some breast cancers are more aggressive than others, researchers say they now understand how cancer cells force normal cells to act like viruses - allowing tumors to grow, resist treatment, and spread. The virus mimic is detected in the blood of cancer patients, particularly in cases of an aggressive type known as triple-negative breast cancer. Researchers from the Perelman School of Medicine at the University of Pennsylvania say cracking the code of how this process works opens up the possibility of targeting this mechanism for treatment.
