Cancer detection

Definition

Cancer detection refers to the process of identifying the presence of cancerous cells or tumors in the body, often at early stages when treatment is more effective. It employs various imaging techniques and biomarkers to reveal the characteristic changes in tissues that indicate malignancy. Effective cancer detection is crucial for improving patient outcomes, guiding treatment decisions, and conducting biomedical research aimed at understanding cancer mechanisms and therapies.
