Toxic Exposures and Cancer Risk: Findings From Two Recent Studies

Endocrine disrupters and cancer riskTwo recent studies have come out with some interesting and important findings about exposures to endocrine disrupters and our risks for cancer.

One widely-reported study examined the risks for breast cancer associated with the use of hair dyes, which contain endocrine disrupters.

And another study looked at the way exposures to endocrine disrupters are measured. This study was not as widely publicized, but its findings could potentially be very significant. Continue reading

A look at several of the most interesting cancer research stories for Summer 2017What’s the latest news in cancer research that stands out the most? In this post, I’ll briefly review several of the most interesting cancer research stories that have been in the news this summer.

These are a few of the recent stories that seem to have the greatest potential impact, at least from my perspective, and that I know I’ll want to follow as they develop further. Continue reading

Cancer Risk and the Environment

The development of cancer is heavily influenced by external factors, a recent study finds.About a year ago, a study published in the journal Science received a lot of attention and comment because it seemed to suggest that most cancers were mainly the result of random mutations or “bad luck.”  I wrote about the study, including what commenters identified as some of its major weaknesses, in a post last January on Cancer Risk and “Bad Luck.”

A new study by a different team, published recently in Nature, revisits the question. It expands on the analysis in last year’s study and examines the question using several different approaches. It arrives at the conclusions that the development of cancer is heavily influenced by external factors. Continue reading

Camp Lejeune, Environmental Toxins And Breast Cancer Risk

What are the links between environmental toxins and breast cancer risk?It’s recognized that environmental factors play a role in the development of many types of cancer, including breast cancer.  But, unfortunately, there are more questions than there are answers right now about the extent of that role. Studies so far have not been able to clarify how and to what extent exposures to harmful substances in the environment increase our risk for breast cancer.

An opportunity to gain some insight on this issue could potentially come from a study now underway of male breast cancer and exposure to contaminated drinking water at Camp Lejeune in North Carolina.  Results from the study are expected some time this year.
