Study finds no association between diet and pancreatic cancer among men and women
... glycemic load and dietary sugar are related to an elevated
risk of pancreatic cancer among women. More research needs to be done to examine individual dietary factors. Prevention is a priority in such a highly fatal disease. Both smoking and obesity increase pancreatic cancer risk and should be considered...

BRCC36 levels compared to normal breast milk-duct cells. "Since BRCC36 directly affects BRCA1 and BRCA1 is activated after exposure to radiation, we wanted to see if BRCC36 might be important in this response," said Xiaowei Chen, Ph.D., a Fox Chase p...
