Women's Health Update: Fibrocystic Breasts

Fibrocystic Breasts

Tender or lumpy breasts are one of the most common reasons why women consult their health practitioner for both assessment, examination and treatment. Many women notice painful or sensitive breasts just prior to menstruation. This has been attributed to a more prominent estrogen than progesterone effect on breast tissue at this time. Sometimes less progesterone is made late in the cycle, as in irregular ovulation. Other women may have average amounts of progesterone but increased tissue sensitivity to estrogen with related fluid retention. Most women tolerate this well enough once reassured it is normal, and the symptoms always resolve with menses. Women who take exogenous estrogen, such as oral contraceptives or estrogen replacement therapy during menopause, may be similarly affected.

Virtually all knowledgeable health care providers agree that the term fibrocystic breast "disease" or "condition" should be abandoned in favor of a more accurate physiologically based description. First of all, the benign breast conditions that are present in almost all of us to some degree should never have been given the "disease" label in the first place. Moreover, the widespread misconception that women with painful or lumpy breasts are at increased risk of breast cancer borders on the tragic. Unfortunately, our health care system requires a diagnostic code to reimburse services, and fibrocystic breast disease has one, even though the medical literature is replete with reasons why it shouldn't. This reinforces misinformation and fear and obscures the safe and simple means that exist for obtaining relief and reassurance.

Given that fibrocystic tissue causing breast pain is not really a disease, energy and effort can be directed toward relieving symptoms and optimizing breast health, as well as increasing the patient's motivation towards general optimal health practices.

Overview of Alternative Treatments

Alternative medicine principles includes the recognition that the liver is the primary site for estrogen clearance or estrogen metabolism. A compromised liver function can lead to a state of estrogen dominance, contributing to texture and density changes in the breast. To assure that estrogens are being metabolized properly, it may be necessary to provide nutritional and herbal support for the liver.

Digestion and elimination are also fundamental factors involved in a more holistic approach to hormone-related health problems. Women having fewer than three bowel movements per week have a risk of fibrocystic breasts four to five times greater than women having at least one movement per day. The longer it takes food to move through the colon, the more waste products pass into the bloodstream, creating a potentially toxic physiological environment. Bacterial flora in the large intestine, such as Lactobacillus acidophilus, improve the transit time of bowel toxins, as well as improving the excretion and detoxification of estrogens. Women on a vegetarian diet excrete two to three times more detoxified estrogens than women on an omnivorous diet.


Removal of caffeine from the diet, is probably the most well-known alternative lifestyle approach for fibrocystic breasts. The first randomized study of a larger number of women was conducted by Dr. Virginia Ernster: 158 women eliminated all caffeine (coffee, tea, cola, chocolate) from their diets for four months, as well as caffeinated medications. She found a significant reduction in clinically palpable breast findings in the abstaining group compared with the control group, although the absolute change in the breast lumps was quite minor and considered to be of little clinical significance. Several other studies have been done, leaving us with mixed reports: three studies show no association between methylxanthines and benign breast disease, and two studies show a correlation with caffeine consumption.

How dietary fat affects the human breast is still confusing and controversial. Reducing the fat content of the diet to 15% of total calories while increasing complex carbohydrate consumption, has been shown to reduce the severity as well as reducing the actual breast swelling and nodularity in some women. Reducing the dietary fat intake to 20% of total calories also results in significant decreases in circulating estradiol.

Nutritional Supplements

For more than 35 years, clinicians have used vitamin E in the medical management of benign breast disease. This practice was initially based on positive reports from small numbers of patients as far back as 1965, and in subsequent studies in 1971, 1978, and 1982. When larger numbers of women were studied, vitamin E did not fare so well, showing no significant effects. However, two studies demonstrated that vitamin E is clinically useful in relieving pain and tenderness, whether cyclical or noncyclical., The studies have been done with varying dosages: 150, 300, or 600 IU daily. In clinical practice, practitioners generally recommend from 400-800 IU of D-alpha-tocopherol with a minimum trial period of two months.

The pain and tenderness of benign breast disease associated with "cyclic mastalgia" have been alleviated with evening primrose oil, the only one of the fatty acids to be scientifically studied in relation to fibrocystic breasts. In a study of 291 women who took three grams per day of evening primrose oil for three to six months, almost half of the 92 women with cyclic breast pain experienced improvement, compared with one-fifth of the patients who received the placebo. For those women who experienced breast pain throughout the month, 27% responded positively to the evening primrose oil, compared to 9% on the placebo. Another study of 73 women received three grams per day of evening primrose oil or placebo, After three months, pain and tenderness were significantly reduced in both cyclical and noncyclical groups, while the women who took placebo did not significantly improve.

Thyroid hormone with low or even normal thyroid function may result in improvement of fibrocystic breasts. These results suggest that iodine deficiency may be a factor in fibrocystic breasts. The breast has an affinity for both thyroid hormone and iodine. Without iodine, the breast tissue becomes more sensitive to estrogenic stimulation, which in turn produces microcysts high in potassium. The potassium is believed to be an irritant that produces fibrosis and eventually cyst isolation. Four types of iodine have been studied in the treatment of fibrocystic breasts, only one of which has been truly effective for both pain reduction and cyst reduction, and free of side effects on the thyroid gland. All forms of iodine relieve subjective clinical symptoms: sodium iodide (Lugol's solution); potassium iodide; caseinated iodine (protein-bound); and aqueous (diatomic) iodine. Symptom relief varied a great deal with the different iodines, but only the aqueous or diatomic iodine achieved both s ymptom relief in 74% of the women, but also objective reduction in nodules and resolution of fibrosis in 65% of the patients, without adverse effects on the thyroid gland. The recommended dose of aqueous iodine is a prescription of 3-6 mg per day.

Supplements that may improve liver function and thereby perhaps a more balanced estrogen metabolism include methionine and choline. B vitamins, particularly B6, can help the liver to properly metabolize and conjugate estrogens. Lactobacillus acidophilus may be able to improve the absorption and transport of estrogen by supporting a normalized intestinal micro flora environment.


Herbal therapies for addressing the symptoms of breast pain, swelling, and cystic nodules in the breast are largely arrived at from traditional uses of herbal medicines and from observational empirical evidence in clinical practice. Herbal diuretics can be useful in decreasing breast swelling and the discomfort associated with it. The most effective of these is dandelion leaf. Other diuretics to consider are galium, yarrow, and uva ursi.

Poke root has been used in traditional naturopathic medical practices for decades. It can be applied as an oil to the breasts and rubbed in like a lotion, reducing painful lumpiness and nodularity.

Herbal support for the liver improves how the liver metabolizes steroid hormones. Traditional herbs that support the liver and the normalization of biochemical steroid pathways may include burdock root, dandelion root, and milk thistle.

Natural Progesterone

If we agree that fibrocystic breasts are at least in part due to a high-estrogen/low progesterone problem, then it is logical to use progesterone therapy as a treatment. Many practitioners and women have experienced that the application of natural progesterone in a cream or gel routinely solves the problem. General use guidelines are 1/4 tsp twice per day -day 15 to day 27. It may be that progesterone is desensitizing the breast to estrogen.


These simple therapies, along with lifestyle modification, generally yield very satisfying results within 1 to 3 months, even in women with significantly painful breasts. Although uncommon, if there is no change after three menstrual cycles, a more aggressive alternative treatment plan must be initiated. If not this, then the conventional medical approaches include decreasing hyperinsulinemia, synthetic progestin, Danazol, Tamoxifen and bromocriptene may have to be contemplated in very difficult unbearable cases.
