Regression
Regression (Medicine)
Regression (pronounced: /rɪˈɡrɛʃən/) is a term used in various fields of medicine to describe the process or state of reduction, decrease, or return. The term is derived from the Latin word 'regressus', which means 'return' or 'retreat'.
In Oncology
In oncology, regression refers to the reduction in size or disappearance of a tumor or cancer after treatment. This can occur naturally or as a result of medical intervention such as chemotherapy, radiation therapy, or surgery.
