A thermography report with a color copy of the thermography results are sent to the patient and/or the patient’s health care provider. The international standardized grading system used in the report is called the Marseilles System of Classification developed by the Pasteur Institute in Marseilles, France.  This scale provides strict criteria for rating breast thermography scans. The scans are reported on a scale of TH-1 to TH-5.

TH-1: normal tissue
TH-2: some changes in tissue i.e. fibrocystic, but normal response to cold challenge
TH-3: suspicious tissue activity with areas not responding to the cold challenge and maintaining higher heat areas
TH-4: abnormal tissue activity with areas not responding to the cold challenge and maintaining higher heat areas
TH-5: severely abnormal tissue activity with areas not responding to the cold challenge and maintaining higher heat areas.

Level TH-1 provides reassurance that the tissue activity is normal and that the appropriate follow-up is screening by thermography in one year.

Level TH-2 indicates that tissue did respond normally to the cold challenge and tissue health can be improved through preventive therapies.

Level TH-3 indicates that close monitoring through ultrasound and professional examination are advised and preventive therapies are needed.

Levels TH-4 and TH-5 require immediate referral for ultrasound exam on the areas specifically located by the breast thermography along with professional examination and other screening methods as indicated and appropriate preventive therapies.
