MINNEAPOLIS (WXOW) -- Researchers at the University of Minnesota have discovered a potential breakthrough in the fight against breast cancer.
Researchers at the school have discovered an enzyme that plays a key role in causing most breast cancers -- and blocking its growth could block cancer.
The University of Minnesota reported the discovery Wednesday. The finding could pave the way for better ways of diagnosing and treating the disease.
The enzyme is the "probable source" of DNA mutations found in most breast cancers.
If scientists can figure out how to block it, they may be able to slow or stop the cancer from growing.
