A strong coffee-drinking habit is being linked to a lower risk of one kind of cancer.  A new study found that women who drank four or more cups of coffee a day were less likely to develop cancer in the uterine lining. Researchers concluded that women who drank that much coffee were one-quarter less likely to get the endometrial cancer.  Still, one scientist says more research is needed before women are advised to increase their coffee intake.  Edward Giovannucci of the Harvard School of Public Health said it would be "premature" to make that recommendation.  Results of the study are published in the journal "Cancer Epidemiology, Biomarkers & Prevention."
