Abstract
Breast cancer is one of the leading causes of death among women worldwide. Survival rate can be improved by early detection of breast cancer and this can be achieved by periodic clinical checkups and self-tests. Mammography, an established technique for diagnosing breast, is an invasive technique but may cause rapture of tumor with possibility of the spread of cancer in area surrounded by lump. Also, it is not reliable for cancer detection in dense breast tissue. Hence, there arises a need of breast cancer detection technique which is more robust, efficient, fast, accurate, non-invasive and can be used for periodical check-ups. Thermography is a non-invasive and non-contact technique of breast cancer detection. Initially rejected for poor sensitivity and accuracy, the technique recently has shown comparable and promising results. Specifically, it shows better performance for younger age women, as well, for dense breast tissues. Being non-invasive, painless and cheap compare to other diagnostic techniques, if accuracy is improved can be used for early detection.
