Measuring certain enzyme activity in urine shows promise for detection of bladder cancer
... telomerase activity was determined using a highly sensitive telomeric repeat amplification protocol (TRAP) assay. Urine samples were processed for cytological (cell) diagnosis and TRAP assay. The diagnosis of bladder cancer was based on bioptic and cystoscopic examinations (direct visual examination of the ur...New study suggests the stomach not the heart offers greater lie detection accuracy

"We can see that while both men and women who use tobacco and alcohol are diagnosed with colorectal cancer at an earlier age, the effect of tobacco is significantly greater in women...American Thoracic Society journal news tips for November 2005 (first issue)
