DENVER -- One of the largest studies ever conducted on  breast cancer shows using genetic information about tumors is paving the way for better treatment options for patients.

The study published in the journal "Nature" reclassifies the disease into ten new categories based on the genetic qualities of a patient's tumor.

Dr. John Lewin, Medical Director of the  Rose Breast Center says the discovery will lead to individually tailored treatment strategies, sparing patients from side effects from treatments they simply don't need.

Dr. Lewin adds, "As we get better and better at that we'll be able to tailor therapy even better and be able to treat women individually and give them only the therapy that's likely to help them."

Identifying genetic patterns in cancerous tumor will also lay groundwork for newer and better drugs to treat patients.

Dr. Lewin emphasis that the first defense against breast cancer is early detection and mammograms are key to catching the disease in it's first stages.

Breast cancer patient Claudia Peterson says a mammogram saved her life and wants other women to realize how important this tool really is.

Claudia warns, "I had a mammogram one year,  the next year I went in and it (cancer) was there just like that, they shouldn't put it off."
