As October Pink, an annual campaign dedicated to raising awareness about breast cancer screening and early detection, begins, researchers are exploring new and innovative ways to identify the disease at an earlier stage. In France, the Kdog project, developed by the Curie Institute, is at the forefront of this effort. This project uses an electronic "nose," a device that can detect specific chemical odors, to identify molecules emitted by breast tumors. These molecules can be analyzed using techniques like chromatography or mass spectrometry, which are commonly used in scientific research. If successful, this method could offer a quick and potentially less expensive alternative to traditional mammograms, and it might be used in various public places, such as pharmacies, train stations, and airports, making early detection more accessible. Once breast cancer is diagnosed, treatment often includes radiotherapy, a method that uses ionizing radiation to destroy cancer cells. Approximately two-thirds of patients undergoing breast cancer treatment will receive radiotherapy. The Curie Institute is working with Thales, a French technology company, to develop a new form of radiotherapy known as "flash" radiotherapy. This method could deliver radiation in just a few seconds, although the intensity of the radiation would be significantly higher—between 1,000 and 10,000 times greater than conventional techniques. The aim is to minimize damage to healthy tissues and reduce the side effects typically associated with radiotherapy, potentially allowing patients to complete treatment in a single session. A preliminary test of this method is planned for 2027, pending successful trials. After treatment, some patients may need prostheses or implants to reconstruct their breast tissue. Lattice Medical, a startup based in Lille, is working on a new type of 3D-printed implant that resembles a grid structure placed under the skin. These implants are designed to support the body's natural tissue regeneration process and are engineered to be gradually absorbed by the body over time. This approach could reduce the risks of rejection and infection, which are common with traditional implants, while also allowing for greater customization to meet individual patient needs. These advancements in detection, treatment, and reconstruction highlight the ongoing efforts to improve the quality of care for breast cancer patients. By combining innovative technologies with traditional medical practices, researchers and medical professionals are striving to make breast cancer treatment more effective, less invasive, and more personalized for those affected.
