The first was published Friday [March 24, 2017] in Science…. When discussing the things that can cause cancer, causes normally fall into one of two broad categories: nature (environmental factors) or nurture (inherited genetic factors). These authors, however, point to a third factor: as we grow, our cells naturally replicate themselves, and in the process, unavoidable DNA replication errors occur which ultimately lead to cancer. The authors calculate that these replication errors or
Secondly, I ran across this interesting paper published [March 2017] in the Journal of the American Medical Association.[According to the study,] 54.6% of deaths from heart disease, stroke, and type 2 diabetes seems to be caused by something other than diet.
Why does all this matter? Because these statistics help us understand the impacts of dietary and lifestyle changes.[E]ven if you could completely eliminate the cancer risk from diet and lifestyle factors, you’d go from a 0.45% chance of getting a new cancer to a 0.30% chance, a reduction of 0.15 percentage points.
