A new screening technique that can detect breast cancer by analyzing urine samples has been developed by a professor of chemistry at Missouri University of Science and Technology.
The technique has been developed by Dr Yinfa Ma who made use of a device known as P-scan which can detect the presence of pteredines (metabolites) in the urine samples. While pteredines are present in the urine samples of all humans, high concentrations can be an indicator of cancer.
Dr Ma revealed that the levels of pteredines in the urine samples continue to rise as the cancer advances. The technique has been tested in a group of 400 people, 300 of whom suffered from breast cancer.
While the technique may not be useful for those who already suffer from breast cancer, it could be helpful in early detection of the cancer with the researchers hopeful of concluding their testing by the end of this year.
