New risks for bladder cancer identified by MIT team

...eam then measured exposure to the arylamines via a technique developed by Tannenbaum's team more than 25 years ago. Arylamines to which a person is exposed react with a protein in the blood, resulting in specific products that can be detected and measured via mass spectrometry. "So what popped out of...
