Cancer cells force normal cells to mimic viruses to help tumors spread, resist treatment

Cancer cells force normal cells to mimic viruses to help tumors spread, resist treatmentIn 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 say cracking the code of how this process works opens up the possibility of targeting this mechanism for treatment.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.
