Making Connections

(via washingtonpost) A fascinating study from University Medical Center in the Netherlands suggests a connection between handedness and breast cancer. Conclusions held up even after factoring for "social and economic status, smoking habits, family history of breast cancer, and reproductive history." The study tracked more than 12,000 healthy, middle-aged women from 1982 to 2000 and found that "...left-handed women in the study were more than twice as likely as right-handed women to develop breast cancer before going through menopause." An increased occurrence of left-handedness had already been linked to intrauterine exposure to the hormonal drug diethylstilbestrol (DES). Researchers are looking to DES as a best-guess for the now found connection between handedness and breast cancer, but it's all guesses right now. The work goes on.

They no longer use this drug (DES)and it was only used in the early 70's for nausea, I believe. So it makes sense that these women are pre-menopausal. Yet another lesson that drugs are not innocuous as many in the population would like to believe.
