EXTERNAL RADIATION Meaning and
Definition
-
External radiation, also known as external beam radiation therapy or teletherapy, refers to a medical treatment that involves the delivery of high-energy radiation to the body from an external machine or device. It is a common method used in cancer treatment, aiming to destroy cancer cells or prevent their growth by damaging their DNA.
This type of radiation therapy relies on the use of X-rays or other forms of radiation such as photons, electrons, or protons, which are generated externally and directed towards the specific area of the body that requires treatment. The radiation is delivered from a machine called a linear accelerator, which emits the high-energy beams that penetrate the skin and reach the targeted tumor or cancerous cells.
External radiation is typically administered in periodic sessions over a period of several weeks, allowing healthy cells to recover between treatments. The treatment plan is carefully designed by a radiation oncologist, who takes into account factors such as the size and location of the tumor, the overall health condition of the patient, and the desired outcome of the therapy.
Given its external delivery method, external radiation therapy allows for precise targeting of the tumor while minimizing the impact on surrounding healthy tissues. However, it may still cause some side effects, such as fatigue, skin irritation or redness, and temporary hair loss in the treated area. These effects vary depending on the individual and the dosage received, and are closely monitored and managed by healthcare professionals throughout the course of treatment.

Etymology of EXTERNAL RADIATION
The word "external radiation" is a compound word that consists of the root words "external" and "radiation".
1. External: The word "external" originated from the Latin word "externus", which means "outward" or "pertaining to the outside". It was derived from the word "exter", meaning "outward" or "on the outside".
2. Radiation: The word "radiation" came from the Latin word "radiatio", which means "a shining" or "beam". It is derived from the verb "radiare", meaning "to emit rays" or "to shine".
Therefore, "external radiation" refers to the type of radiation therapy that is applied from outside the body, directed towards the affected area, typically used to treat cancer.
