Caffeine and Sore Breasts

Many women experience sore breasts in the days or weeks leading up to their periods. Most often this is part of a benign condition known as "fibrocystic breast changes," which is caused by normal hormonal variations. While caffeine does not cause fibrocystic changes, many women find that reducing caffeine intake before their period reduces the soreness in their breasts.

Fibrocystic Breast Changes

Fibrocystic breast changes are normal changes in breast tissue that occur in response to varying levels of the female hormones estrogen and progesterone, according to the American Congress of Obstetricians and Gynecologists. The most common pattern is a thickening and swelling of the breast that becomes more tender in the days just before your period. Typically the pain and swelling will resolve once your period starts.

Caffeine's Effect on Breast Tissue

Some women find that reducing caffeine intake in the days before their period decreases breast tenderness. It is not clear what effect caffeine has on the breast tissue. The American Academy of Family Physicians states that three different studies failed to prove a connection between caffeine avoidance and reduction of breast pain. In her book "Women's Encyclopedia of Natural Medicine" Tori Hudson, a naturopathic doctor, acknowledges these studies but states that she recommends abstaining from caffeine for women with sore breasts and that many, but not all, find relief.

Other Remedies for Sore Breasts

Since breast soreness is thought to be caused by the effect of hormones on the breasts, oral contraceptive pills are often prescribed. For some women, this helps; for others, it makes the problem worse. Natural approaches include supplementation with vitamin E or evening primrose oil. Some women find relief from wearing a very supportive bra, such as a sports bra, when their breasts are sore.

Dangers

Fibrocystic changes are not associated with breast cancer. The American Academy of Family Physicians states that most breast pain resolves on its own. If your breast soreness is interfering with your daily activities; if it persists regardless of your menstrual cycle; if the soreness is accompanied by fever or nipple discharge; or if you notice a non-painful mass, see your doctor immediately. These may be signs of a more dangerous condition.
