Understanding your medical notes
Mammogram results explained: what does my result mean?
A mammogram result often arrives as a short letter with a "BI-RADS" category or a request to come back for more images — wording that can be worrying without context. This guide explains the BI-RADS scale, what terms like calcifications and dense tissue mean, and why a recall rarely means cancer.

Radiologists summarise a mammogram using a standard scale called BI-RADS. It tells your doctor what was seen and what to do next:
| Category | What it means |
|---|---|
| 0 | Incomplete — more images or a previous scan are needed to decide |
| 1 | Normal — nothing of concern seen |
| 2 | Benign — a harmless finding (e.g. a cyst or calcifications) |
| 3 | Probably benign — very likely harmless; a short-interval follow-up is suggested |
| 4 | Suspicious — a biopsy is usually recommended to be sure |
| 5 | Highly suggestive of cancer — biopsy strongly recommended |
| 6 | Known cancer — already confirmed by a previous biopsy |
The large majority of screening mammograms are category 1 or 2.
Other common mammogram terms, decoded
| Term | What it means |
|---|---|
| Recall / callback | An invitation back for more images or a closer look — usually not cancer |
| Calcifications | Tiny calcium deposits — very common and usually benign |
| Microcalcifications | Smaller calcium specks; certain patterns prompt a closer look |
| Mass | An area with shape and edges; can be a cyst or other finding |
| Dense breast tissue | More glandular/fibrous than fatty tissue — common and normal |
| Asymmetry | An area that differs between the two sides; often benign |
| Well-defined | Clear, smooth edges — often a reassuring feature |
| No significant abnormality | Nothing of concern seen — reassuring |

What to do when your result arrives
- Find the BI-RADS category or headline result.
- Read what happens next — routine recall, a follow-up in a few months, or further tests.
- Don't panic at a callback — most lead to a normal or benign result.
- Note any dates for follow-up images or appointments.
- List your questions for your GP or the breast clinic.
Unsure what your letter means?
Patiently AI turns "BI-RADS 2, benign calcifications, routine recall" into plain English — and explains what's reassuring and what, if anything, to follow up.

- In plain terms, what does my result or BI-RADS category mean?
- Do I need more images, a follow-up, or any further tests?
- If I've been recalled, what's the most likely explanation?
- Does dense tissue affect what my result can show?
- When is my next routine mammogram due?
Patiently AI generates personalised "Questions for your doctor" automatically from your letter — so you feel prepared, not anxious.
Frequently asked questions
What is a BI-RADS score on a mammogram?
BI-RADS is a standard 0–6 scale radiologists use to summarise a mammogram. 0 = more images needed; 1 = normal; 2 = benign; 3 = probably benign with short follow-up; 4 = suspicious, biopsy suggested; 5 = highly suggestive of cancer; 6 = cancer already confirmed by biopsy. Most screening mammograms are 1 or 2.
Does being recalled after a mammogram mean I have cancer?
No. A recall means the radiologist wants more images or a closer look — often because of overlapping tissue or an unclear area. The large majority of people recalled after screening do not have cancer. It's a normal part of careful screening, not a diagnosis.
Are breast calcifications a sign of cancer?
Usually not. Calcifications are tiny calcium deposits and are very common, especially with age — most are completely benign. Occasionally the pattern of certain small calcifications prompts a closer look, but on their own they're most often harmless.
What does dense breast tissue mean?
It means you have relatively more glandular and fibrous tissue than fatty tissue. It's common and normal, but it can make mammograms slightly harder to read, so your team may mention it or suggest additional views. It's a description, not a disease.
Can Patiently AI explain my mammogram result?
Yes. Paste your result letter — or upload a photo, PDF, or Word file — and Patiently AI explains what the result and any BI-RADS category mean in plain English, decodes the terminology, and suggests questions to ask. It's free, needs no account, and removes identifying details on your device before processing.
