New risks for bladder cancer identified by MIT team
...ir paper. Specifically, they analyzed blood samples
from some 600 of the people involved in the study. Half had bladder cancer; the others did not but were matched against their counterparts for such things as age, sex and neighborhood. The team then measured exposure to the arylamines via a te...
