Your report explained
Radiology terms in your report: spiculated, architectural distortion and more
A radiology report describes shapes, edges and patterns. It is not a diagnosis. The radiologist is saying what an area looks like, how concerned they are, and what should happen next. This page translates the words that frighten people most, and points you to the one line on the report that actually carries the meaning.

The short answer
What do the words on a breast scan report mean?
A radiology report describes shapes, edges and patterns. It is not a diagnosis. The radiologist is saying what the area looks like and how concerned they are, then giving it a score that tells your doctor what to do next.
Why the language sounds so alarming
Words like spiculated and distortion are technical descriptions, not judgements about how bad things are. They exist so that one doctor can describe a picture precisely to another. Read on your phone at midnight, they land very differently from how they were meant.
The score at the end is the part that matters
Most breast reports finish with a category, usually written as BI-RADS followed by a number. That single number carries more meaning than any adjective in the body of the report, because it says directly what should happen next.
If you read nothing else on the report, find the category number and the recommendation line.On your report
The descriptions, in plain language
- Mass
- A three-dimensional lump seen on more than one view. The word says nothing about whether it is cancer.
- Spiculated
- An area with fine lines radiating from it, like a star. This pattern raises concern and usually leads to a biopsy.
- Circumscribed
- A smooth, clearly defined edge. This is generally a reassuring description.
- Architectural distortion
- The normal fanning pattern of breast tissue is pulled out of shape without an obvious lump. It is taken seriously and usually sampled.
- Microcalcification
- Tiny specks of calcium. Extremely common. The pattern and grouping matter far more than their presence.
- Asymmetry
- An area that differs from the same place on the other side. Often normal tissue, and usually checked with extra views.
- BI-RADS
- The final score. It runs from a normal study through probably harmless, to suspicious, to known cancer, and each level has a recommended next step.

What the score is actually telling your doctor
Each level is tied to an action. That is the whole purpose of the system.
Incomplete
More pictures are needed before anything can be said. This is the category behind most screening recall letters, and it is not a finding in itself.
Normal or benign
Either nothing was found, or something was found and is confidently harmless, such as a simple cyst. You return to routine screening.
A named benign finding is a result, not a worry.Probably benign
Very likely harmless, but worth looking at again sooner than usual rather than sampling. This is where short-interval follow-up comes from.
Suspicious, or highly suggestive
A biopsy is recommended. The higher levels signal how strongly the radiologist suspects cancer, which helps your team plan, but tissue is still what gives the answer.
Ask at this point
- What is my category
- What is the recommended next step
- How soon should it happen

Being straight with you
What a scan report cannot tell you
It cannot tell you whether you have cancer. No scan can. Imaging describes appearance, and appearance overlaps: harmless things can look worrying and some cancers look unremarkable. Only tissue under a microscope settles it.
It also cannot tell you your stage
People read a size in millimetres on a report and try to work out their stage from it. Scan measurements are estimates and often differ from what is measured after surgery. Stage comes from the pathology report.
Two radiologists can word it differently
Some of this language is judgement. A report from one centre may sound more alarming than another describing the same pictures. This is why the category and the recommendation matter more than the adjectives, and why comparing your wording with someone else's is not useful.
What to do with the report
Find the category and the recommendation. Take the report and the images, not just the printed summary, to your appointment. Ask your doctor to point at the area on the screen. Seeing it usually does more to settle the fear than any amount of reading.
Keep your own copy of everything
Ask the imaging department for the pictures on a disc or a drive, not only the typed report. Any doctor giving you a second opinion will want the images themselves, and having your own set avoids repeating scans later simply because the originals cannot be found. Keep them with your biopsy report in one folder, and take that folder to every appointment.
Commonly believed
What people conclude from the wording
It is a concerning pattern and it does usually lead to a biopsy, but scar tissue from previous surgery and some harmless conditions produce the same appearance. The word describes a shape. The biopsy gives the answer.
They have nothing to do with your diet, your calcium tablets or your bones. They are tiny deposits that form in breast tissue for many reasons. Stopping calcium supplements will not change them and may harm your bones.
Scan measurements are estimates and frequently differ from the size measured after surgery. Stage also depends on the nodes and on whether disease has reached other organs. A number in millimetres on its own settles nothing.
It is a specific category with a specific action: look again sooner rather than take a sample now. It exists to avoid putting thousands of women through biopsies for findings that almost never turn out to be cancer. Keep the follow-up appointment.
Questions we are asked
Common questions about imaging reports
My report says BI-RADS 4. Does that mean cancer?
It means suspicious enough that a biopsy is recommended. That category covers a wide range, from mildly to strongly suspicious, and a large share of biopsies in it turn out not to be cancer. Ask your doctor where within the category yours sits.
Should I ask for a second reading of my scan?
It is reasonable where the report is unclear or where a decision turns on it. Ask for the images themselves on a disc, not only the typed report, because a second opinion on the pictures is what actually helps.
What does architectural distortion mean for me?
It means the normal fanning pattern of tissue is pulled out of shape without an obvious lump. It is taken seriously and usually sampled, because it can be the only sign of some cancers. It can also be old scar tissue from previous surgery.
Why does my report mention breast density?
Because dense tissue makes a mammogram harder to read and slightly raises risk. It is a normal finding, extremely common, and not a disease. It may be a reason your team adds an ultrasound to your screening.
The report mentions a clip. What is that?
A tiny marker placed at the time of a biopsy so the exact spot can be found again. It is harmless, stays put, and does not set off airport scanners. It is especially useful if chemotherapy shrinks the area before surgery.
Can I get my images, not just the report?
Yes, and you should. Ask the imaging department for a disc or a digital copy. Any doctor giving a second opinion will want the pictures, and having your own copy avoids repeating scans unnecessarily later.
My report says correlate clinically. What does that mean?
It means the radiologist is asking your doctor to read the pictures alongside your examination and history. It is standard wording and is not a hint that something was found. Your doctor will do exactly that at your appointment.
How soon should a biopsy happen after a suspicious report?
Within days to a couple of weeks in most systems. If you have been given no date, chase it rather than waiting for a call. A planned short wait is normal; an open-ended one is worth pushing on.
