A new method of detecting breast cancer using the urine has been developed by researchers at the Department of Obstetrics and Gynecology of the Medical Center, University of Freiburg.

The molecules, referred to as microRNAs, enter into the urine over the blood, and by determining the composition of microRNAs in the urine, the scientists succeeded in establishing whether a test subject was healthy or diseased with 91% accuracy.

Should the effectiveness of the method be confirmed in further studies, it could serve as a means of monitoring the success of treatment and potentially also of making an early diagnosis of breast cancer in the future.

The study included 24 healthy test subjects and 24 women who had recently been diagnosed with a breast tumor.

The patients were in tumor stages 1, 2, or 3. It will now be necessary to conduct further studies to confirm the effectiveness of the method with larger groups of patients.

The Freiburg scientists published their findings in the journal BMC Cancer and have applied for a patent for the method.
