A new breast change deserves a clinical conversation, even after a recent normal mammogram. Describe what changed and ask which evaluation is appropriate. Many changes are benign, but touch, appearance or a home test cannot reliably establish the cause.
This guide is for anyone with breast tissue who has noticed a change or is preparing for an examination. It also explains how investigating symptoms differs from routine screening.
Record what is different for you
Changes to report include a new lump or thickening in the breast or underarm, a change in breast size or shape, skin dimpling or redness, a newly turned-in nipple, or nipple discharge other than breast milk. Mention persistent focal pain as well. NCI's symptom guidance recommends follow-up for a breast change even when a recent mammogram was normal.
When booking, say that you have a symptom so the service can arrange the appropriate appointment. Describe where it is, when you first noticed it, whether it is changing, and any related skin or nipple change. Include pregnancy or breastfeeding, hormone medicines, prior breast procedures and previous imaging. Ask how promptly you should be seen and what changes should trigger an earlier call.
Familiarity with your usual appearance and feel can help you describe a change. Repeatedly checking or squeezing an area does not turn it into a diagnosis. Keep a brief record and arrange assessment.
Match the test to the question
On a small screen, scroll the table sideways. Keyboard users can focus the table region and use the arrow keys.
| Step | Purpose | What to clarify |
|---|---|---|
| Clinical examination | A clinician asks about the change and examines the breasts and relevant nearby areas. | What did you find, and what question remains? |
| Screening mammogram | Looks for possible cancer in people without symptoms. | Which schedule fits my risk and history? |
| Diagnostic imaging | Investigates a symptom or an abnormal screening finding; extra mammographic views and/or ultrasound may be used. | Which area are we evaluating, and will I receive results today? |
| Biopsy | Collects tissue so a pathologist can establish what the cells are. | Who will explain the result and arrange the next step? |
NCI's mammogram guide explains screening and diagnostic imaging. A callback may mean that more views or another test are needed. It is a request to resolve a finding, not a cancer diagnosis. NCI's diagnosis guide explains the role of biopsy when tissue confirmation is needed.
For help preparing for imaging or understanding a callback, use the mammography guide to 2D and 3D imaging, breast density and results.
Keep routine screening on a separate track
For the U.S. population covered by its average-risk recommendation, the USPSTF recommends mammography every two years from age 40 through 74. Its 2024 recommendation includes cisgender women and other people assigned female at birth, with specified exclusions for high-risk histories. Known high-risk genetic variants, prior breast cancer and certain prior chest-radiation exposures call for a different discussion.
Other organizations use different schedules. Ask which recommendation your clinician is applying and why it fits you. Decisions after 74 and about additional imaging for dense breasts need individualized discussion. A screening timetable is not a reason to wait for evaluation of a new symptom at any age.
Prepare for a comfortable, useful appointment
Bring prior imaging details and reports if available, a medication list, and the change record. Ask whether the service needs the actual earlier images as well as the written report. Comparisons with earlier mammograms can help the radiologist interpret a finding.
Tell the clinician if you are worried about pain, a previous difficult examination or privacy. Ask them to explain each step, request a chaperone or support person according to the service's arrangements, and say if you need to pause. Ask the imaging facility for its own preparation instructions before your visit.
Close the loop after a result
Before leaving, write down the result or the expected reporting date, the person responsible for contacting you, and the recommended follow-up. If the result is described as normal but the original change persists, ask how the finding and symptom fit together and what reassessment is planned.
For a proposed commercial test, ask what it measures, whether it is validated for your situation, and what action follows each possible result. An investigational nipple-fluid test or another marketed alternative should not displace a recommended clinical assessment, imaging or biopsy.
