The functionality of cancer monitoring devices varies based on their type and purpose. For example, imaging devices use advanced technologies like magnetic resonance or radioactive tracers to create detailed images of the body's internal structures. Wearable devices often use sensors to collect physiological data, which is then analyzed to detect any anomalies. Blood tests and liquid biopsies involve collecting a small sample of blood, which is analyzed for specific cancer markers. Genomic sequencing requires a sample of tumor tissue or blood, which is then sequenced to identify genetic mutations.
