Lifetime caffeine intake and the risk of epithelial ovarian cancer
Caffeine has bad press. Studies have suggested that caffeine may exacerbate various conditions including, diabetes, osteoporosis, hypertension, bleeding disorders, and schizophrenia. Previously a link with ovarian cancer has been suggested. This retrospective study seems to disprove the suggestion.
Total lifetime caffeine consumption was calculated for 497 women with ovarian cancer and compared to 904 women who did not. Only a very few of each group did not consume caffeine either in coffee, tea or cola. Patterns of caffeine consumption were similar for both groups.
Risk assessment showed that overall; those women who had the highest caffeine intake did not have any increased risk. It was noted that pre-menopausal women who were high caffeine consumers did have an increased risk. However, this is a small number of women and may be a coincidence.
