DOSE FRACTIONATION Meaning and
Definition
-
Dose fractionation refers to the practice of dividing a therapeutic radiation dose into smaller fractions or doses and delivering them over a period of time, rather than administering the entire dose in a single session. This technique is commonly used in radiation therapy to treat various types of cancers.
When radiation therapy is applied to treat cancer, it is crucial to strike a balance between delivering enough radiation to kill cancer cells while minimizing damage to healthy tissues. By dividing the desired total radiation dose into smaller fractions, dose fractionation allows the healthy tissues to repair and recover between radiation sessions, while cancer cells are continuously exposed to radiation in a controlled manner. This enables the cancer cells to be effectively destroyed while reducing the risk of severe side effects.
Dose fractionation has several advantages. It allows for better tumor control by increasing the total dose of radiation that can be delivered without exceeding the tolerance of healthy tissues. It also promotes tissue repair and recovery, improving the overall outcome of the treatment. Additionally, fractionated doses of radiation are often better tolerated by patients, as the side effects are generally reduced compared to high-dose single sessions.
Overall, dose fractionation plays a crucial role in radiation therapy by optimizing the therapeutic ratio between tumor control and normal tissue damage, leading to improved treatment outcomes and patient well-being.

Etymology of DOSE FRACTIONATION
The etymology of the word "dose fractionation" comes from the combination of two terms: "dose" and "fractionation".
1. Dose: The word "dose" can be traced back to the Greek word "dosis", which means "a giving". It entered English from the Latin word "dosis", which also means "a giving" or "a dose". The concept of dosage has been used in medical and pharmacological contexts for centuries, referring to the quantity of a substance administered to achieve a specific effect.
2. Fractionation: The word "fractionation" comes from the Latin word "fractus", which means "broken" or "divided". It is derived from the verb "frangere", which means "to break". Fractionation refers to the process of dividing or splitting something into fractions or smaller parts.
