NEW BRUNSWICK - Scientists have uncovered new information about the genetics of breast cancer.

A published study in the journal "Nature" says there are four different types of breast cancer. It also says each cancer has its own history and responds differently to treatment.

The new findings could spell big changes, including new drugs and treatments, in treating breast cancer.

The study was based on tumors in 825 patients. It's the first full scale genetic analysis of breast cancer.
