Breast lump

Considerations:
A lump in the breast has different significance at different ages and for different sexes. Since some lumps and some changes are considered normal, understanding the structure of the breast and how it functions may help eliminate some concerns.

The first lump to concern parents is often the lump found beneath the nipple of the newborn infant. This is true breast tissue that is enlarged in response to circulating maternal estrogens and will decrease over subsequent months as maternal estrogen effects decrease. The breast enlargement may be found in both male and female infants and is not only normal, but expected. The size of the breast is used in evaluating how close to term the newborn infant is.

The next most worrisome lump is that found in girls, often as young as 6 years old. A

Common Causes:

Note: There are other causes of a breast lump. This list is not all inclusive, and the causes are not presented in order of likelihood. The causes of this symptom can include unlikely diseases and medications. Furthermore, the causes may vary based on age and gender of the affected person, as well as on the specific characteristics of the symptom such as location, quality, time course, aggravating factors, relieving factors, and associated complaints. Use the Symptom Analysis option to explore the possible explanations for a breast lump, occurring alone or in combination with other problems.

Home Care:
Treatment for known, diagnosed fibrocystic breast changes includes the following: Perform a breast self examination monthly; wear adequate bras for good breast support; and avoid caffeine . The effectiveness of vitamin E , vitamin B6 , and herbal preparations such as evening primrose oil are somewhat controversial and should be discussed with your health care provider. Oral contraceptives may be prescribed because they often decrease symptoms.

For a lump in the breast caused by a benign cyst , see your health care provider who may take a biopsy or aspirate (use a needle and syringe to obtain a sample of fluid) to be sure the cyst is benign.

For a lump in the breast caused by an injury, it should clear up eventually without treatment.

For a lump in the breast caused by a drug reaction, consult with your health care provider about discontinuing the offending drug. NEVER CHANGE MEDICATIONS WITHOUT CONSULTING YOUR HEALTH CARE PROVIDER.

For a lump in the breast caused by cancer , follow the provider's recommendations for appropriate treatment. The choice of initial treatment for biopsy-confirmed breast cancer is based upon the extent of the disease and it aggressiveness. Currently, breast cancer is viewed as a systemic disease that requires both local and systemic treatment. Local treatment may include lumpectomy , mastectomy (partial, total, or radical with axillary dissection) and radiation therapy , all directed at the breast and surrounding tissue. Systemic treatment includes chemotherapy and hormonal therapy--both of which circulate throughout the entire body to, hopefully, eliminate cancer cells that may be present in distant parts of the body. Most women receive a combination therapy including surgery, radiation, chemotherapy, or hormonal therapy.

Note: Self monitoring of a breast lump may be done in premenopausal women for 1 to 2 months to observe for any cyclical changes associated with the menstrual period. Self care may also include restricting dietary fat to approximately 25% of the total daily calorie intake and eliminating caffeine intake and cigarette smoking to see if symptoms subside.

Call Your Healthcare Provider If:

  • there is any unexplained breast lump! EVERY breast lump should be checked by the health care provider.
  • you are a woman, 20 years or older, unfamiliar with how to perform breast self-examination .
  • you are a woman, 40 years or older, with no baseline mammogram .

There are 3 general rules:
1) ALL lumps should be checked three ways--by breast self-examination, by the health care provider, and by mammography .
2) Any new breast lump, particularly if painless and located in one breast, could be cancer until proven otherwise.
3) Many breast lumps need to be biopsied, particularly if the results of mammography do not clearly show the lump to be benign .

What to Expect:
A complete history should be obtained, with special attention to factors that increase the patient's risk of breast cancer . A thorough breast examination will be performed. If you don't know how to perform breast self-examination , ask your health care provider to teach you the proper method.

Medical history questions documenting breast lumps include:

  • How did you notice the lump?
  • What part of the breast is affected?
  • How many lump(s) are present?
  • Are both breasts affected?
  • Has there been an injury to the breast(s)?
  • What other symptoms are present?

Diagnostic tests that may be performed include:

  • cytologic examination of nipple discharge (a study of the types of cells)
  • mammography
  • needle aspiration or open biopsy of the nodule to see if the fluid indicates a cyst
  • thermography (similar to mammography)
  • transillumination
  • mammography to delineate a breast mass
  • ultrasound to detect cancer .
  • breast biopsy to confirm or rule out suspected cancer in solid masses:
    • needle biopsy involves removal of cells for evaluation directly from the mass (can be done in conjunction with needle aspiration procedure)
    • incisional biopsy involves surgical removal of a portion of the mass for evaluation
    • excisional biopsy includes surgical removal of entire mass for evaluation

After seeing your health care provider:
You may want to add a diagnosis related to a breast lump to your personal medical record.


A breast self examination should be performed monthly by all adult women. Early detection of breast cancer results in a higher cure rate and survival rate. Increased awareness, routine breast exams, and regular mammograms allow for earlier detection of breast cancer. Increased longevity is just now beginning to show as survival statistics are being compiled.
