Microcalcifications, Fibrocystic Breasts, Cysts, and Other Breast Conditions
There are several breast conditions a woman may experience that are not cancer. Many will produce a noticeable lump, many will be detected in your annual mammogram, but others will only be noticed through other symptoms, such as pain or discharge. Many of these conditions require no treatment.
Although your condition may be benign, it’s important to let your doctor know if you notice any changes to your breasts.
This section includes information on the following conditions:
- Microcalcifications
- Fibrocystic Breasts
- Fibroadenoma
- Simple Cysts
- Lipoma
- Intraductal Papilloma
- Breast Pain
- Nipple Discharge
Microcalcifications
Microcalcifications are tiny deposits of calcium clustered together in the milk ducts.
Symptoms
Microcalcifications have no symptoms that a woman will notice herself (like a lump).
Diagnosis
Microcalcifications will show up on a mammogram as tiny white flecks in the tissue. Many times these are not cancer; however, in some instances they are associated with very early cancer ( ductal carcimona in situ). Consequently, they need to be investigated thoroughly.
In order to evaluate microcalcifications more carefully, additional magnification views are taken during a mammogram. Sometimes a biopsy may be necessary to definitively determine if the microcalcifications are cancerous or not.
Treatment
If the microcalcifications are not cancerous, which they most often are not, there is nothing you need to do. If a biopsy is recommended and the microcalcifications are found to be ductal carcinoma in situ, you will be referred to a surgeon by your referring physician.
Fibrocystic Breasts
Fibrocystic changes occur in about half of all women, mostly during child bearing years. The cause appears to be normal hormonal fluctuations because the symptoms of fibrocystic breasts usually increase right before menstruation and subside after menstruation. Additionally, these monthly changes usually stop after menopause.
Fibrocystic breast changes used to be referred to as a disease. Since the condition is so prevalent, it is no longer considered a disease.
Symptoms
The following symptoms of fibrocystic breasts usually peak right before menstruation. They can range from mild to severe.
- Breast pain and tenderness
- Thickened, lumpy areas in the breast tissue
- Feeling of fullness in the breasts
- Noncancerous cysts
- Nipple discharge or sensation changes
Diagnosis
Mammogram results for women with fibrocystic breasts may be more difficult to read due to the breast tissue being more dense (more fibrous, cystic, and glandular relative to fatty). However, a definitive diagnosis can be made with a combination of mammography, ultrasound and sometimes a minimally invasive needle biopsy.
Treatment
If you have fibrocystic breasts, there is no further treatment necessary. If you have severe or persistent pain though, talk to your doctor.
Some of the following self help measures may alleviate symptoms:
- Restrict fat intake to 25% or less of daily calories
- Eliminate caffeine from the diet
- Wear a well-fitting bra with good support
- Take certain vitamin or herbal supplements – discuss this with your doctor
- Use oral contraceptives – discuss this with your doctor
Additional Information
Women with this condition may find it more difficult to perform a breast self examination. It’s important to monitor the monthly changes in your breast tissue so you will notice if there are any new changes.
Fibroadenomas
A fibroadenoma is a benign (non-cancerous) growth in the breast that is made up of breast cells and fibrous tissue. This condition is more common in younger women and can develop quickly, sometimes within a few months. It will not become cancerous and does not increase your risk of developing breast cancer.
Symptoms
Larger fibroadenomas tend to be round and distinct from surrounding breast tissue and may feel like a marble in the breast.
Diagnosis
Fibroadenomas usually appear as dark gray masses on a mammogram. A definitive diagnosis can be made with a combination of breast ultrasound and a minimally invasive needle biopsy.
Treatment
Surgery is not usually required, but many doctors will recommend it if the fibroadenomas continue to grow or change the shape of the breast.
Having surgery could cause the loss of some normal breast tissue and cause scarring and changes in the shape of the breast. This could also make future exams and mammograms more difficult to interpret.
If a woman chooses not to have surgery, it is important that she have regular clinical breast exams to ensure that the mass isn’t growing.
Additional Information
Sometimes a new fibroadenoma will grow after one is surgically removed.
Simple Cysts
A cyst is a little pocket of fluid in the breast. It occurs when a milk duct becomes blocked, preventing the normal breast fluid to flow through the ducts. The trapped fluid forms a pocket that starts off small, but can grow larger as more fluid builds up. It’s possible to have multiple cysts.
Symptoms
You may or may not be able to feel cysts in your breasts, depending on their size.
Following are some symptoms you may experience with cysts:
- Round, moveable lump that may be tender to the touch
- Fluctuation in the size of lumps that corresponds with hormonal changes
- Breast discomfort or pain
Diagnosis
A cyst will appear on a mammogram as a round or oval gray structure. Ultrasound can provide an accurate diagnosis of cysts.
Treatment
Cysts do not become cancerous and do not need to be surgically removed. If the cyst is painful, it can be drained (aspirated) using ultrasound to guide a tiny needle.
Additional Information
In a small percentage of women, cysts will re-form after being drained.
Cysts may be caused by fibrocystic breasts. Refer to this section for more information.
Lipoma
A lipoma is a pocket of fat that’s encased by a fibrous band. They are not cancerous and do not increase your risk of getting cancer. Lipomas are quite common and harmless. They more commonly occur in post-menopausal women.
Symptoms
Lipomas may or may not be felt. If you can feel one, it will be usually be soft and moveable.
Diagnosis
A lipoma will show on a mammogram as a translucent gray mass. A clear diagnosis can be made with ultrasound and sometimes a minimally invasive needle biopsy.
Treatment
Lipomas do not need to be removed surgically.
Intraductal Papilloma
An intraductal papilloma is a tiny, wart-like growth in a milk duct, often in the large milk ducts near the nipple. These growths are seldom cancerous and generally affect women between the ages of 35 and 55.
Symptoms
Intraductal papillomas don’t always produce symptoms. The most common symptom experienced is a spontaneous bloody or sticky nipple discharge. You may also feel a small lump behind and near the edge of your nipple.
Diagnosis
The diagnosis can be made with a ductogram followed by mammography, ultrasound and a minimally invasive needle biopsy.
Treatment
The intraductal papilloma may or may not need to be removed. Surgical removal will be recommended if the papilloma is large or associated with atypical cells.
Breast Pain
Some women may experience breast pain without an apparent cause. Breast pain is seldom associated with breast cancer.
Possible Causes
Following are possible causes of breast pain:
- Fibrocystic breasts
- Hormone replacement therapy after menopause
- Stress
- Diet, particularly caffeine, mushrooms, nuts, cheese, red wine, bananas, chocolate, and fat in excess
- Mastitis, or inflammation of the mammary gland (also causes redness, swelling and tenderness of the breast) – this condition may require medical attention
Diagnosis
A mammogram, and possibly a breast ultrasound, may be requested by your health care provider to assist in the evaluation of breast pain.
Treatment
There is no specific medical treatment for alleviating breast pain. Following are some measures you can take to reduce pain:
- Restrict fat intake to 25% or less of daily calories
- Eliminate caffeine from the diet
- Wear a well-fitting bra with good support
- Take certain vitamin or herbal supplements – discuss this with your doctor
- Your doctor may consider oral contraceptives in the appropriate setting
It is always important to discuss breast changes or pain with your physician, have yearly mammograms beginning at age 40, and continue regular breast self examination.
Nipple Discharge
Tiny droplets of fluid may appear on the nipple surface or clothing. There is normally fluid in the milk ducts even if a woman is not pregnant or nursing. Discharge of fluid can be caused by squeezing (such as during a mammogram), sexual stimulation, a warm shower or other pressure to the breast.
Identifying Abnormal Discharge
Nipple discharge does not always indicate a problem. Further evaluation is necessary when the discharge:
- Is spontaneous – it comes out by itself without squeezing or nipple manipulation.
- Comes out of only one opening in the nipple - not multiple.
- Is bloody, clear or clear-yellow in color - place discharge on a white tissue to check the color.*
*Green, gray or milky discharge does not usually need further breast diagnostic studies. These secretions may be caused by hormonal stimulation, fibrocystic changes, some medications and rarely, a pituitary gland dysfunction.
Possible Causes
Fibrocystic breasts and Intraductal Papilloma are both common causes of nipple discharge. Breast cancer is an uncommon cause.
Diagnosis & Treatment
A nipple discharge exam called a Ductogram may help identify the cause of the discharge.
With this exam, a tiny catheter is placed in the nipple opening where the discharge is seen. Contrast material is injected and then a mammogram is performed. The contrast material makes it easier to see abnormalities on the mammogram.
If an abnormality is seen, an ultrasound may be performed to further evaluate it.
It’s also possible that a minimally invasive needle biopsy will be done. A biopsy can usually remove and diagnose the problem. The discharge is usually gone after that. Most women have minimal discomfort with this procedure
