In a preliminary, small study of 98 samples of urine, all from men—24 who had cancer, and 74 with bladder-related problems but no cancer yet used a gas chromatograph to successfully examine the vapor from heated urine samples to canncer cancer.
Radiological studies such as CT scans or ultrasound do not have sufficient sensitivity to be useful for detecting bladder cancers.
