Final Answer:
The term that means giving radiation in small, repeated doses is "fractionation."
Step-by-step explanation:
Fractionation: Fractionation is the process of delivering radiation therapy in smaller, divided doses over several sessions. This approach helps minimize damage to healthy tissues while effectively treating the targeted cancer cells.
Radiation Therapy: This term refers to the medical use of ionizing radiation to treat various diseases, particularly cancer. It works by damaging the DNA inside cells, preventing them from growing and dividing. Fractionation involves breaking down the total prescribed dose of radiation into smaller fractions. Each fraction is administered over separate treatment sessions, allowing normal tissues to recover between exposures while maintaining the overall therapeutic effect on cancer cells.
