Researchers say they were able to identify four genetically-distinct types of cancer - which will lead to new treatments. The new treatments could include using drugs already approved for cancers in other parts of the body. It will also lead to more personalized and precise treatments.

Dr. Lora Barke, with Invision Sally Jobe in south metro Denver, saysthe new study is encouraging.

"It allows us to help diagnose breast cancer better. It helps us to then treat breast cancer in the way that it needs to be treated specifically for that patient," Dr. Barke said.

Breast cancer kills 35,000 women a year in the United States.

Dr. Barke says because they are so many different types of cancer, it's extremely important to see your doctor. 

"Get screened with mammography. Because mammography does save lives. It allows us to find breast cancer before it actually can be found by palpitation or a self exam," Dr. Barke said.

Dr. Barke said breast-cancer screening has also become very personalized. 

"What we're doing, is now we're able to determine if a patient may need something more than mammography to help in terms of finding that breast cancer early."
