Swedish researchers found that eating foods that were high in acrylamide did not cause breast cancer. To wit: During a mean follow-up of 17.4 years, a total of 2,952 incident cases of breast cancer were diagnosed in the cohort. In multivariate analyses controlling for breast cancer risk factors, no statistically significant association was observed between long-term acrylamide intake (assessed at baseline and in 1997) and the risk of breast cancer, overall or by estrogen receptor (ER) and progesterone receptor (PR) status.
Interestingly, in looking through media reports about acrylamide, I've found many hostile responses in the Comments sections, some calling the info "junk science." How valid are the accusations? Who knows? But it seems that some researchers consider the substance to be a danger.
