U-M study challenges notion of using Herceptin only for HER2-positive breast cancer

A new University of Michigan study found that the protein HER2 plays a role even in breast cancers traditionally classified as HER2-negative. The research suggests that the drug Herceptin may have a greater impact on treating breast cancer and preventing its spread, particularly when given early to prevent tumor recurrence.
