What do Thermography ratings/scoring mean?
What Do the Ratings Mean?
Breast thermography commonly uses a scale from TH-1 to TH-5.
Think of this as a spectrum — from very balanced, stable patterns through to patterns that need closer attention and follow-up.
TH-1 (Very Stable)
This is the most balanced pattern.
- Symmetrical thermal patterns
- Low vascular activity
- No areas of concern
This is what we consider an ideal baseline, and ongoing routine monitoring is recommended.
TH-2 (Stable)
Still within a healthy range.
- Slight variations may be present
- Normal vascular patterns
- No significant thermal concern
This is very common and typically just monitored over time.
TH-3 (Intermediate)
This is where we begin to monitor a little more closely.
- Some asymmetry or increased activity
- May reflect hormonal influence or mild inflammation
A follow-up scan is often recommended to observe stability or change.
TH-4 (Needs Closer Observation)
This rating indicates more significant thermal patterns.
- Noticeable asymmetry
- Increased vascular activity
- Patterns that require careful monitoring
At this stage, we may suggest:
- Short-term follow-up imaging
- Additional support strategies
- Referral for further investigation if appropriate
TH-5 (Significant Thermal Findings)
This rating shows stronger patterns that need prompt attention.
- Significant asymmetry
- Marked vascular activity
- Patterns that require further investigation
At this point, we will guide you clearly on the next steps, which may include medical referral.
Important Things to Remember
- These ratings are not a diagnosis
- They do not confirm or rule out disease
- They are a tool for monitoring and early awareness
Thermal imaging is about observing how your body is functioning — particularly inflammation and circulation — so we can respond early and support your health.
Why This Matters
One of the greatest benefits of thermography is the ability to:
- Track changes over time
- Identify subtle shifts early
- Take a proactive, supportive approach to breast health
Your body is always communicating — this is simply another way of listening.
