The March 4 issue of JNCI includes a study showing that even moderate alcohol consumption in women increases the risk of cancer; an analysis of the relationship between smoking, lung cancer risk, and socioeconomic status in Europeans; and a study showing that the drug Goserelin improves long-term survival in premenopausal women with early breast cancer. Also in this issue are clinical trial results showing that gene expression patterns change in prostate tumors after just a few weeks of vitamin E and selenium use; a study showing that a model called 'MMRpredict' is best able to identify colorectal cancer patients who should undergo genetic testing; and an animal study demonstrating that a fluorescent fusion protein can be used to track cancer stem cells.
