periods. These symptoms are called fibrocystic breast changes. They may also be
called cyclic breast changes, because they come and go with your
changes are normal and harmless. They aren't cancer, and they don't increase
your chance of getting breast cancer.
But having fibrocystic
breast changes can make it harder to find a lump that could be cancer. This is
a special concern if you also have a higher-than-normal risk for breast cancer.

radiation treatment or a breast biopsy showing atypical ductal hyperplasia (ADH), talk to your doctor

think that fibrocystic breast changes are linked to the hormone changes that
happen during a woman's menstrual cycle. Each month, a woman's body gets ready for a

You don't need to do anything about fibrocystic breast changes. They are normal, and they don't lead to cancer.
If breast pain bothers
Although there is no evidence that any of these help with breast pain, some
women report that they feel better when they give up caffeine; eat a very low-fat diet; or
