Follow-up after breast lump evaluation

If the breast lump isn't cancerous, a health care provider will decide if there's a need for short-term monitoring with clinical breast exams or repeat breast imaging. You may be asked to return in 2 to 3 months to see if there have been changes in your breast. Consult your provider if you notice changes in the lump or develop new areas of concern.

A diagnosis in question might result in further consultation with a surgeon or other specialist. A diagnosis might be in question, for example, when a clinical breast exam and the mammogram show areas of suspicion, but the biopsy is benign.

A cancerous breast lump requires treatment. The tumor type and other factors will influence treatment options.

How breast tissue feels

Breasts contain tissues of different textures, including fat, glands and connective tissue. Some breast-related symptoms, such as tenderness or lumpiness, change with the menstrual cycle. Lumps during this time might be caused by extra fluid in the breasts. Breast tissue also changes during pregnancy and menopause and while taking hormones.

Imaging tests

To further evaluate a breast lump, a care provider might recommend:

Diagnostic mammogram. This specialized breast X-ray shows breast changes. It takes X-ray pictures from several angles.
Breast ultrasound. Sound waves create images of the inside of the breast on a monitor. Ultrasound imaging is helpful for determining whether a breast lump is solid or filled with fluid.
Breast MRI. An MRI machine uses a magnet and radio waves to create pictures of the interior of a breast. A breast MRI usually is reserved for when the diagnosis is in question. Before a breast MRI, a dye might be injected through an intravenous (IV) line in an arm to enhance the appearance of tissues or blood vessels on the MRI pictures.

Newer tests for breast imaging are being developed and studied.

Breast biopsy

This involves having a tissue sample removed and examined under a microscope (biopsy). Ultrasound or mammography might help guide the needle, and a local anesthetic might be used. Breast biopsy options include:

Fine-needle aspiration biopsy. With a thin needle attached to a syringe, cells and fluid are removed from the suspicious area.
Core needle biopsy. A larger needle with a special tip is used to remove a sample of breast tissue.
Stereotactic biopsy. Mammography produces images of the area in question from several angles (stereo images). A health care provider then removes a sample of breast tissue with a needle.
Vacuum-assisted biopsy. A probe connected to a vacuum device removes a small sample of breast tissue.
Surgical excisional biopsy. A small cut is made in the skin and breast tissue to remove part or all of a lump.

After a biopsy, the tissue sample is sent to a lab for analysis. A health care provider explains the results.

Procedures to evaluate a breast lump

Finding a breast lump or other change in a breast might cause worry about breast cancer.

That's understandable. But breast lumps are common. Most often they're noncancerous (benign), particularly in younger women. Still, it's important to have any breast lump evaluated by a health care provider, especially if it's new or if one breast feels different from the other breast.

What to expect during a clinical breast exam

Evaluation of a breast lump typically begins with a clinical breast exam. During this exam, a health care provider will likely:

Ask about symptoms and risk factors for breast cancer or benign breast conditions
Examine the breasts and lymph nodes in the armpit, feeling for lumps or any other differences
Examine the skin on the breasts
Check for nipple problems, such as inversion or discharge

If the care provider finds a breast lump or other area of concern, you'll likely need testing.

When to consult a health care provider

Being familiar with how breasts usually feel makes it easier to detect when there's a change.

Reasons to consult a health care provider include:

Finding a new breast lump or thickening that feels different from the surrounding tissue or the other breast
Noticing a change in the size, shape or appearance of a breast
Having breast pain that doesn't go away after the next period
Noticing skin changes on a breast, such as itchiness, redness, scaling, dimpling or puckering
Having a newly inverted nipple
Noticing nipple discharge
