Exploring Radiation Therapy

Radiation therapy is a type of cancer treatment that uses high-energy beams to destroy cancer cells. This treatment is a local therapy, which means it targets a specific area of the body. The primary goal of radiation is to damage the DNA of cancer cells, which stops them from growing and dividing. Over time, these damaged cells die and are eliminated by the body.

There are different types of radiotherapy. The one chosen by your radiology specialist will depend on the type, size, and location of the tumor. The external beam radiation is a common type. It uses a machine outside the body, called a linear accelerator, that aims radiation at the cancer.

Internal radiation, another type of radiotherapy, uses a radioactive source placed inside your body, in or near the tumor. Treatment is often administered daily over several weeks. This schedule allows for enough radiation to destroy cancer cells while giving healthy cells time to recover between sessions.

Preparing for Treatment

Before starting radiation therapy, you will have a planning session called a simulation. During this appointment, your radiation oncology team will map out the precise area of your body to be treated. This process uses imaging scans, such as a CT scan, to help the team accurately target the tumor while avoiding nearby healthy tissue.

Your team may also create molds or other devices to help you stay in the same position for each treatment. They will also mark the treatment area on your skin with small, often permanent, dots. These marks make sure the radiation is directed to the exact same spot during every session.

Undergoing Treatment Sessions

Radiotherapy itself is a straightforward process. The radiation therapist will help you get into the correct position on the treatment table using the marks and any positioning devices made during your simulation. Once you are correctly positioned, the therapist will leave the room and go to a control area nearby. They will watch you on a monitor and be able to communicate with you through an intercom. The machine will deliver the radiation, and you will not feel anything during this time. After the treatment is complete, you can resume your normal daily activities.

Recovering From Side Effects

Radiotherapy can cause side effects, which vary depending on the part of the body being treated and the dose of radiation. Common side effects include fatigue and skin changes in the treatment area, such as redness or soreness. Most side effects are temporary and can be managed with the help of your healthcare team.

Your radiology specialist and care team will monitor you closely throughout your treatment. They will provide guidance on managing side effects and will support your recovery. It is fundamental to communicate any symptoms or concerns you have with your team so they can assist you effectively.
