All infrared breast examinations are placed in a specific TH (thermobiological) risk category. The higher TH rating, the higher your risk of future breast cancer and the chance that a cancerous tumor is present.
Colder Areas
Hotter Areas
TH 1 –Normal Non-Vascular Image
Normal with minimal risk of cancer.
When compared to each other, both breasts are even in temperature and cool (dark colors).
TH 2 –Normal Vascular Image
Normal with minimal risk of cancer.
Evenly distributed areas of heat (blood vessels) in both breasts.
If present, specific vascular patterns indicate increased estrogen activity.
TH 2 –Normal Vascular Image
Normal with minimal risk of cancer.
Evenly distributed areas of heat (blood vessels) in both breasts.
If present, specific vascular patterns indicate increased estrogen activity.
TH 3 –Equivocal Image (questionable)
Classified between normal and abnormal.
One breast with a single thermovascular finding.
Early follow-up infrared examination is indicated to monitor the stability and/or possible progression of any noted regions of interest.
TH 4 –Abnormal Image
Abnormal with a higher possibility that cancer is present.
More aggressive heating (blood vessels) in one breast vs. the other.
Higher risk of future breast cancer when other tests are negative.
Early follow-up infrared examination is indicated.
TH 5 –Severely Abnormal Image
Severely abnormal with a higher possibility that cancer is present.
Highly aggressive heating (blood vessels) in one breast vs. the other.
Higher risk of future breast cancer when other tests are negative.
Early follow-up infrared examination is indicated.
