Thermography
Thermography uses an infrared camera to detect heat emissions from the targeted body region. Digital infrared thermal imaging is the thermography used to diagnose breast cancer. This method shows high accuracy and is a cost-effective form of diagnosis. The concept behind this test is that as cancer cells multiply, they need more oxygen-rich blood for growth. As there is an increase in blood flow to the tumor, the temperature around the tumor also increases. Malignant cells discharge nitric oxide into the bloodstream and cause impairment in the microcirculation [22]. This released nitric oxide, along with the active growth of the cancerous cells, increases blood circulation and temperature in that particular region. Therefore, evaluating these differences in temperature leads to the detection of the malignant region in the breast [23].
