Getting a call or letter that says your OBSP mammogram results are abnormal can feel scary. We see this reaction all the time. Take a breath. In most cases, abnormal OBSP results do not mean cancer. They mean the radiologist saw something that needs a closer look.
At Ontario Breast Screening Program clinics across Ontario, follow-up imaging is a normal and expected part of breast screening. In our experience, many women who come back for additional tests leave with reassurance and clear answers within weeks.
This guide walks you through what abnormal OBSP results mean, what happens next, and how to move forward with confidence.
Abnormal OBSP Mammogram Results: What They Mean and What Comes Next
An abnormal mammogram simply means the images were not completely clear or showed a change that needs more detail.
Common reasons we see include:
- Dense breast tissue that makes images harder to read
- Overlapping tissue that looks suspicious on a first scan
- Small calcifications that need magnification
- A new shadow or asymmetry compared to prior exams
We’ve had patients tell us they assumed the worst. After follow-up imaging, most were relieved to learn everything was normal.
Received Abnormal OBSP Results? Here’s What Ontario Patients Should Expect
If your OBSP results are abnormal, the process usually looks like this.
First, you are contacted by the screening program or your imaging clinic. This may be a phone call or a mailed letter. You are then referred for follow-up imaging at an OBSP referral imaging clinic.
In many cases, the clinic will help book the next appointment for you. If not, you will be given clear instructions on how to book follow-up mammogram Ontario services.
This step is about clarity, not diagnosis.
OBSP Abnormal Results Explained: Follow-Up Tests, Timelines, and Referrals
Most OBSP next steps happen quickly. We often see follow-up imaging scheduled within one to three weeks.
Possible follow-up tests include:
- A diagnostic mammogram Ontario exam with focused views
- A breast ultrasound after abnormal mammogram results
- Short-term imaging follow-up in a few months
Only a small number of patients are referred for biopsy. Even then, many biopsy results come back benign.
What Does an Abnormal Mammogram Mean Under OBSP Screening?
An abnormal OBSP mammogram meaning is very different from a diagnosis. OBSP is designed to be cautious. Radiologists prefer to double-check rather than miss anything.
We’ve seen many cases where a spot that looked concerning on the screening exam disappeared with better imaging. That’s exactly why the system works.
OBSP Next Steps After an Abnormal Mammogram: A Step-by-Step Guide
Here’s what we typically recommend to patients.
- Read the letter or message fully
- Book your follow-up imaging as soon as possible
- Bring prior mammogram history if available
- Ask questions at your appointment
- Avoid searching worst-case scenarios online
Knowledge reduces fear. Clear steps make the process easier.
Ontario Mammogram Abnormality Results: When to Worry—and When Not To
It’s normal to worry. It’s not always necessary.
In our experience:
- Most abnormal mammogram Ontario findings are benign
- Dense breasts often trigger follow-up
- Early detection improves outcomes when something is found
OBSP abnormal results are part of a careful screening system, not a sign that something is wrong.
From Abnormal OBSP Results to Diagnosis: How the Follow-Up Process Works
If additional imaging still raises questions, a biopsy may be recommended. This is not common, but it is part of standard breast exam follow-up Ontario care.
Biopsies are outpatient procedures. Results are usually available within days. Many come back showing cysts, fibroadenomas, or normal tissue.
We’ve seen patients walk in terrified and walk out relieved. That matters.

These are signs you’re getting detailed care, not bad news.
