Breast cancer is a type of cancer that forms in breast cells, this type of cancer is very common, diagnosed in most cases in women. Approximately 5% to 10% of breast cancers are estimated to be associated with inherited genetic mutations. It is important to know that most breast lumps are benign and not cancerous (malignant), it means that there are tumors that are not life threatening because they spread outside the breast, but if it should be examined by a specialist to obtain a clearer diagnosis of what it could be. That is why in this research work the detection of suspicions of breast cancer using thermal images is proposed, because some discomfort presented in the breast could be identified in time and determinate if it could possibly be a benign or malignant cancer, in addition keeping in mind that the analysis does not require physical contact with the patient and, furthermore, the infrared camera does not produce a congenital defect, being ideal for quick analyzes and to rule out illnesses. It was obtained as a result that the patients with suspicions of breast cancer, were a little reluctant to the diagnosis of the image processing, but after checking it with a specialist they were surprised, it was also identified that the different temperature between the body and breast cancer is 3 °C to 5 °C.
