Lifestyle and home remedies
To minimize discomfort associated with breast cysts, you might try these measures:
- Wear a supportive bra. If you have breast pain from a breast cyst, good support to surrounding breast tissue may help relieve some discomfort.
- Avoid caffeine. There's no scientific proof that caffeine consumption is linked to breast cysts. However, many women find relief from their symptoms after eliminating caffeine from their diets. Consider reducing or eliminating caffeine — in beverages as well as in foods such as chocolate — to see if your symptoms improve.
- Reduce salt in your diet. Although studies on salt restriction and cyst formation aren't conclusive, some experts suggest that reducing salt in your diet may help. Consuming less sodium reduces the amount of excess fluid retained by your body, which in turn may help alleviate symptoms associated with a fluid-filled breast cyst.
Alternative medicine
Evening primrose oil is a fatty acid (linoleic acid) supplement that's available over-the-counter. Some evidence suggests that evening primrose oil, taken alone or in combination with vitamin E, may help minimize cyclic breast pain that can be associated with breast cysts. Although the exact mechanism isn't clear, experts believe that women deficient in linoleic acid are more sensitive to hormonal fluctuations during the menstrual cycle, resulting in breast pain associated with breast cysts.
