Consumption of coffee, tea and caffeine consumption was assessed in,, and the follow-up continued through
This updated meta-analysis was conducted to assess the association between coffee consumption and breast cancer risk. We conducted a systematic search updated July to identify observational studies providing quantitative estimates for breast cancer risk in relation to coffee consumption. A total of 26 studies 16 cohort and 10 case—control studies on coffee intake with breast cancer cases were included in the meta-analysis.

The German study compared the health histories, including coffee drinking, of 3, women diagnosed with breast cancer after menopause to the health histories of 6, similar postmenopausal women not diagnosed with breast cancer. The researchers adjusted for differences in health factors linked to breast cancer risk between the diagnosed and undiagnosed women.
Health headlines always seem to include a study about caffeine, and whether or not caffeine consumption is linked to breast cancer is often raised. While there are many unanswered questions about this, experts are learning that caffeine probably does not increase the likelihood of developing the breast cancer. In fact, it may decrease risk in some women, though more research is certainly needed.
Specific coffee subtypes and tea may impact risk of pre- and post-menopausal breast cancer differently. We investigated the association between coffee total, caffeinated, decaffeinated and tea intake and risk of breast cancer. A total ofwomen participating in the European Prospective Investigation into Nutrition and Cancer EPIC Study, completed a dietary questionnaire from toand were followed-up until for incidence of breast cancer.
