Students of Engineering in Computer Systems at the National Technological Institute of Mexico, campus Oaxaca, created a wizard to help detect early breast cancer, which was tested in 1,200 individuals, showing very promising results.
Nowadays, breast self-examination for early detection breast cancer is still a rare habit among the Mexican population, both men and women. In most cases, physicians perform the test when people visit their offices.
To facilitate the procedure, the team of students created “Pinktest”, advised by Dr. Marisol Altamirano Cabrera, which assists and teach patients the techniques needed for a proper self-examination.
The wizard uses adhesive paper, which is placed in the breasts without the need of undressing. The next step is to use a camera that works with infrared light and detects the adhesive paper, marking in its surface the manual patterns needed for self-examination.
Since the camera detects depth, it can record whether the test is performed correctly; that is, if the force and detail are correct, otherwise indicating to start the examination again. The information that the device generates is processed by a free piece software that produces a three-dimensional model.
“The camera also detects heat. This is important because having nodules in the body increases the temperature in the area. So, the apparatus detects temperature changes in the skin. In this way the generated information gives rise to the interpretation of the doctor, who will determine whether it is needed to analyze to verify or rule out the presence of suspicious tissue, not necessarily malignant,” explained Dr. Altamirano Cabrera, Head of Department of Computer Systems the National Technological Institute of Mexico, campus Oaxaca.
Pinktest participated in April 2017 in the international contest Exporecerca XVIII Jove 2017, held in Barcelona, Spain, where it won third place in the category for Research Projects at Higher Education. The event is organized by the Association for the Promotion of Young Research and the prototype was chosen from over 720 projects from countries around the world.
Students Roberto Sánchez Flores, Wilfrido Colmenares Alavez and Valente Guevara Lopez said their project is mainly directed to rural population, where groups of users will be trained for its operation and medical students will periodically check the progress on the user’s interaction with the system.
