Does caffeine cause breast cysts?

Answers from Sandhya Pruthi, M.D.

No, caffeine doesn't appear to cause breast cysts (fibrocystic breast changes), a noncancerous (benign) breast disease. There's also no evidence to suggest a link between caffeine and breast cancer.

Anecdotally, some women report that breast pain symptoms improve when they go off caffeine or reduce the amount of caffeine in their diets. Although no research has documented this effect, it's OK to go to go caffeine-free to see if it relieves discomfort from breast cysts.
