In medicine, "cm" stands for centimeter, a unit of length measurement equal to one-hundredth of a meter. It's commonly used to express the size of anatomical structures, lesions, or the distance between anatomical landmarks.
For instance, a doctor might describe a tumor as being "2 cm in diameter" or a patient's height as "170 cm". This measurement is crucial for accurate diagnosis, treatment planning, and monitoring the progress of diseases.
