Researchers have taken a giant step forward in understanding the different types of breast cancer, some similar to one other, some not.

"The findings add to growing evidence suggesting that tumors should be catalogued and treated based on the genes that are disrupted rather than their location in the body,"  according to the researchers.

This discovery may help scientists target treatments in a more specific way by identifying the genetic profile of tumors, hopefully leading to more effective treatments.
