"The method is better than mammography, which can only be used when the disease has already occurred," said Rasmus Bro, professor of chemometrics at the University of Copenhagen in Denmark."It is not perfect, but it is truly amazing that we can predict breast cancer years into the future," Bro stressed.

While a mammography can detect newly developed breast cancer with a sensitivity of 75 percent, the new metabolic blood profile is able to predict the likelihood of a woman developing breast cancer within the next two to five years with a sensitivity of 80 percent, the study noted.

"When a huge amount of relevant measurements from many individuals is used to assess health risks - here breast cancer - it creates very high quality information. The more measurements our analyses contain, the better the model handles complex problems," continued professor Bro.The model does not reveal anything about the importance of the single biomarkers in relation to breast cancer, but it does reveal the importance of a set of biomarkers and their interactions, the researchers said.
