New formation of blood vessels is seen in cancer cells/region. when there is hemoangiogensis in a focal lesion there will be increased blood supply. This will cause increase in temperature .This can be detected easily by thermography before the focal lesion is felt by finger as a palpable lump. With this advantage the cancer can be detcted in a very early stage that is before the patient has symptoms of before the doctor see a lump
Thermography is a painless, non invasive, state of the art clinical test without any exposure to radiation and is used as part of an early detection program which gives women of all ages the opportunity to increase their chances of detecting breast disease at an early stage.
This patient was also age 37 when her first baseline thermogram showed a slight hyperthermic asymmetry in the upper right breast. The follow-up study showed the pattern had become more well defined and although clinical correlation did not find anything remarkable it was decided to repeat the exam again in a further 3 months, when again significant changes were seen. Mammography was performed at this stage with the thermographic guidance of the locally suspicious area at 1 O’clock to the right nipple. The mammographic findings were inconclusive and the patient was referred for a repeat mammogram in 12 months. Thermographic monitoring was continued and at the fifth comparative study at 12 months significant changes were still evident and the hyperthermic asymmetry (temperature differentials) had increased. Immediate further investigation was strongly recommended despite a scheduled mammogram in 6 months, and at the patients insistence a repeat mammogram was performed which clearly showed a small calcification (1 mm) at 1 O’clock. Within one week a lumpectomy had been performed with good margins and the pathology confirmed as a malignant carcinoma (DCIS). This patient has now had stable thermograms for the last 2 years and is expected to remain healthy.
The results of this routine study led to the diagnosis of inflammatory carcinoma in the right breast. There were no clinical indications at this stage. (Thermography can show significant indicators several months before any of the clinical signs of inflammatory breast disease, skin discoloration, swelling and pain). Inflammatory breast disease cannot be detected by mammography and is most commonly seen in younger women, the prognosis is always poor. Early detection provides the best hope of survival.
This 37 year old patient presented for routine thermographic breast screening, she was not in a high risk category and had no family history. No breast exams had been performed previously. The vascular asymmetry in the upper left breast and the local hypothermia at 11 O’clock was particularly suspicious and subsequent clinical investigation indicated a palpable mass at the position indicated. A biopsy was performed and a DCIS of 2 cm was diagnosed.
Thermography is an important tool in Breast cancer Screening. The chemical and blood vessel activity in both precancerous tissue and the area surrounding the tissue in breast cancer is almost always higher than in the normal breast. However precancerous and cancerous masses are highly metabolic tissues and they need a large supply of nutrients to maintain their growth. So to do this they increase circulation of their cells by sending out chemicals to keep existing blood vessels open and create new ones (neoangiogenesis). This process results in an increase in surface temperatures of the breast. Breast Thermography uses an infrared camera and computer to detect analyze and produce high resolution images of these temperature changes in the breast.
