More than 825 patients of breast cancer took part in the study with the researchers analyzing the DNAs of the tumors and found that they fell into four distinct classes.

The researchers said that their finding could allow for more specialized and effective treatments which may include drugs currently available in the market.

"With this study, we're one giant step closer to understanding the genetic origins of the four major subtypes of breast cancer. Now we can investigate which drugs work best for patients based on the genetic profiles of their tumors", lead researcher Dr Matthew Ellis said.
