Etymology
The term 'detection' is derived from the Latin word 'detectus', which means 'to uncover' or 'to discover'.
In Medicine
In medicine, detection often refers to the process of identifying a disease or medical condition. This can be achieved through various methods such as medical imaging, laboratory testing, and physical examination. Early detection of diseases, such as cancer, can significantly improve the chances of successful treatment and survival.
