Hyperfractionated radiation therapy

Hyperfractionated radiation therapy is a type of radiation therapy that is given in smaller amounts and more frequently than standard radiation therapy. Hyperfractionated radiation therapy is used to treat certain types of cancer, including head and neck cancer and lung cancer.

Overview

Hyperfractionated radiation therapy is a form of external beam radiation therapy that uses a linear accelerator to deliver high-energy x-rays to a tumor. The goal of this therapy is to kill cancer cells while minimizing damage to healthy tissue.

Procedure

In hyperfractionated radiation therapy, the total dose of radiation is divided into small doses, or fractions. The fractions are given more than once a day. This allows a higher total dose of radiation to be given in a shorter period of time than with standard radiation therapy.

Benefits

Hyperfractionated radiation therapy can be more effective than standard radiation therapy in treating certain types of cancer. This is because cancer cells may be more sensitive to radiation if it is given in smaller amounts and more frequently.

Risks

As with any form of radiation therapy, there are risks associated with hyperfractionated radiation therapy. These can include skin reactions, fatigue, and other side effects depending on the area being treated.
