Thermobiological Risk Ratings

The Thermogram Center provides a TH Rating to assess each breast’s risk for developing cancer.

Thermobiological Risk Ratings* are a unique component of Advanced Thermography at The Thermogram Center and are not available from basic thermographers in Colorado.

Breast series include 7-11 views/images of the breasts. These images are analyzed by a Board Certified Clinical Breast Thermologist for thermal findings, including: temperature differences between the breasts that exceed the norm; vascular asymmetries; and thermal patterns/abnormalities consistent with cancer and/or other physiological activities.

Examinations result in a TH (thermobiological) rating – or risk category – for each breast. The greater the number and severity of thermal findings in a breast, the greater the TH rating. The risk of developing breast cancer increases with higher TH ratings.

The benefit of Risk Assessing Thermal Imaging, then, is that each breast’s cancer risk is assessed a Thermobiological Risk Rating – a simple number you can use to monitor your thermobiological level of risk over time.

If you are uncomfortable with your thermobiological level or risk… or it is increasing over time… We can discuss potential risk factors in your images, educate you on likely causes, and provide action steps, tools and resources for a healthier tomorrow.

In addition to providing Thermobiological Risk Ratings, The Thermogram Center uniquely measures the highest risk factor for developing breast cancer – prolonged exposure to excess estrogen – with a Hormonal Grade on a Scale of 0 – 4.

Each breast is assessed a TH rating on the following scale: 

Left Image: TH1 – Lowest Risk; Right Image: TH2 – Low Risk

– Lowest and low thermobiological risk of developing cancer.

– 12 month thermal imaging follow-up for women over 30 years of age.

– Clients are advised to follow their doctor’s recommendations regarding breast screening, and maintain a healthy lifestyle.

Left Image: TH3 – Medium Risk

– Medium thermobiological risk of developing breast cancer.

– Early thermal imaging follow-up is recommended to monitor signs of stability and/or change, typically at 6 months. When subsequent imaging indicates stability, standard 12-month follow-up is typically recommended.

– Clients are advised to follow their doctor’s recommendations regarding breast evaluation, maintain healthy lifestyles, and consider exploring opportunities to reduce risk factors with a qualified health provider.

Left Image: TH4 – HighRisk; Right Image: TH5 – Highest Risk

– High and highest thermobiological risk for developing breast cancer.

– Clients are strongly recommended to: obtain further evaluation, i.e. ultrasound; and optimize their risk factors with prevention efforts, potentially including testing/recommendations from functional health provider.

– Early thermal imaging follow-up is indicated in an attempt to discern transient and benign conditions, i.e. infection, lymphatic congestion, inflammation from cancerous conditions given the average doubling time for active cancer is typically 3 – 6 months.

NOTE: The Thermogram Center is not a treatment or diagnosing center. While clients may be imaged at The Thermogram Center with the images analyzed/interpreted by its interpretive service provider, any treatment and/or diagnoses obtained by the client are through his/her health provider(s).
