Understanding Radiation Therapy Basics

It’s important for patients to know the basics of radiation therapy. This treatment uses high-energy particles or waves to kill cancer cells. It targets a specific area of the body.

What Is Radiation Therapy and How Does It Work

Radiation therapy damages cancer cells’ DNA, stopping them from growing. This damage comes from high-energy radiation. It can be from a machine outside the body or a radioactive material inside.

The aim is to give the right amount of radiation to the tumor. This way, it harms the cancer cells but not the healthy tissues around them. New technology has made this treatment more precise, reducing side effects.

Common Types of Radiation Treatments

There are several types of radiation therapy, each used for different reasons. The main types are:

• External Beam Radiation Therapy (EBRT): This is the most common type. A machine outside the body sends radiation beams to the tumor.
• Internal Radiation Therapy (Brachytherapy): This involves placing radioactive material inside the body, close to the tumor.
• Stereotactic Body Radiation Therapy (SBRT): It uses high doses of radiation for small tumors in a few sessions.
• Intensity-Modulated Radiation Therapy (IMRT): A type of EBRT that changes the radiation beam’s intensity. This makes treatment more precise and spares healthy tissues.

Knowing these basics helps patients make better choices about their care. It also prepares them for what to expect during treatment.

How to Prepare for Radiation Therapy: Essential First Steps

Before starting radiation therapy, it’s important to prepare well. You need to understand the process, talk to your radiation oncologist, and gather important information.

Initial Consultation with Your Radiation Oncologist

Your first meeting with the radiation oncologist is key. They will explain your treatment plan and what to expect. This is also a chance to ask questions and get a clear understanding of the process.

Questions to Ask Before Starting Treatment

It’s helpful to ask questions before starting treatment. You might want to know about side effects, how to manage them, and what support is available.

• What are the possible side effects of radiation therapy?
• How can I handle side effects during treatment?
• What support services are there for me during treatment?

The Simulation Appointment: What to Expect

Knowing what to expect at your simulation appointment can make you feel less anxious. It helps you get ready for radiation therapy.

Purpose of the Simulation Session

The simulation session is a key part of getting ready for radiation therapy. Your team will use CT scans to map out the area to be treated. This helps us pinpoint the tumor or area needing treatment.

Key objectives of the simulation session include:

• Determining the optimal treatment position.
• Identifying the precise area to be targeted by radiation.
• Creating a customized plan tailored to your specific needs.

Positioning and Immobilization Devices

To ensure accurate radiation therapy, staying in the same position is key. We use molds, casts, or masks to keep you in the right spot.

Device Type	Purpose	Benefits
Molds or Body Casts	To immobilize the body or a specific part.	Ensures consistent positioning, reducing movement during treatment.
Head and Neck Masks	To secure the head and neck in place.	Provides precise targeting of the treatment area, minimizing exposure to surrounding healthy tissues.
