Exterior Means for Premature Recognition of Breast Cancer

This research is aimed at the early detection of breast cancer. Breast cancer is a form of cancer that is found in the breast tissue. Though mostly common in women, research has shown that it can also be diagnosed in men. The increasing trend in the mortality rate attributable to breast cancer can be traced to inefficient methods of detecting the cancer in its early stage. Current methods involve invasion, exposure of the patient to radiation, and/or compressing the breast. These may cause pain or even invest patient with other forms of ailments. In this work, infrared (IR) thermography has been deployed to detect breast cancer in its early stage. IR thermography uses IR radiation to measure heat patterns of human skin. It is passive in nature and it neither emit harmful radiation nor subject the patient to further risks. The thermograms captured by infrared camera are analysed by a software in stages, viz: extraction of region of interest, detection and masking of warm region among others. The resulting image in grayscale is sampled by comparing the white pixels (warm region) to the dark pixels (cool region). The software subsequently compares the outcome with a predefined threshold to predict the chances of occurrence of cancer and displays result for further diagnosis by medical expert. Our proposed modality is cost effective, safe and user friendly.
