What Is Radiation Therapy?

Radiation therapy, often referred to as radiotherapy, is a medical treatment that uses high doses of radiation to kill or damage cancer cells. It is a common and effective method for treating various types of cancer, either alone or in combination with other treatments such as surgery and chemotherapy. The primary goal of radiation therapy is to target and destroy cancerous cells while minimizing damage to surrounding healthy tissue.

Radiation therapy can be administered in two main forms:

• External Beam Radiation Therapy (EBRT): This is the most common type, where a machine called a linear accelerator directs high-energy beams of radiation from outside the body to the tumor.
• Brachytherapy: In this method, radioactive sources are placed directly inside or very close to the tumor, allowing for a higher dose of radiation to the cancer cells while sparing nearby healthy tissue.

Radiation therapy is typically used to treat localized cancers, meaning those that have not spread extensively. It can also be used to shrink tumors before surgery or to relieve symptoms in advanced cancer cases. Understanding the role of radiation therapy in cancer treatment is crucial for patients and their families as they navigate their treatment options.

How Radiation Therapy Works

The effectiveness of radiation therapy lies in its ability to damage the DNA of cancer cells. When the DNA is damaged, the cancer cells are unable to grow and divide, leading to their eventual death. Here’s a closer look at how radiation therapy works:

The Mechanism of Action

Radiation therapy primarily works through two mechanisms:

• Direct Damage: Radiation can directly break the DNA strands in cancer cells, leading to cell death.
• Indirect Damage: Radiation can also ionize water molecules in the body, creating free radicals that can further damage the DNA of cancer cells.

Because cancer cells are more sensitive to radiation than normal cells, radiation therapy can effectively target tumors while minimizing harm to surrounding healthy tissue. However, some healthy cells may still be affected, which is why understanding the side effects of radiation therapy is essential for patients.

Planning and Delivery of Radiation Therapy

The process of radiation therapy involves several steps to ensure that the treatment is as effective and safe as possible:

1. Consultation: Patients meet with a radiation oncologist to discuss their diagnosis, treatment options, and potential side effects.
2. Simulation: A simulation session is conducted to determine the exact location of the tumor. This may involve imaging tests like CT scans.
3. Treatment Planning: Based on the simulation, a personalized treatment plan is created, detailing the radiation dose and the number of sessions required.
4. Delivery: During treatment sessions, patients lie on a treatment table while the radiation machine is positioned to deliver precise doses of radiation to the tumor.

Each session typically lasts only a few minutes, and most patients undergo treatment five days a week for several weeks, depending on their specific case.

What to Expect During Treatment

Many patients wonder, “Is radiation therapy for cancer painful?” The good news is that the treatment itself is generally painless. However, some patients may experience side effects, which can vary based on the treatment area and individual response. Common side effects include:

• Fatigue
• Skin irritation or redness in the treated area
• Nausea
• Changes in appetite

It’s important for patients to communicate openly with their healthcare team about any side effects they experience, as there are often ways to manage them effectively.

1. External Beam Radiation Therapy (EBRT)

External Beam Radiation Therapy (EBRT) is the most common form of radiation therapy. It involves directing high-energy beams, such as X-rays or protons, from outside the body to the tumor. This method allows for precise targeting of cancer cells while minimizing damage to surrounding healthy tissue.

• 3D Conformal Radiation Therapy: This technique uses advanced imaging to create a 3D model of the tumor, allowing for more accurate targeting.
• Intensity-Modulated Radiation Therapy (IMRT): IMRT adjusts the intensity of the radiation beams, providing a more tailored approach to treatment.
• Stereotactic Body Radiation Therapy (SBRT): SBRT delivers high doses of radiation in fewer sessions, making it a time-efficient option for certain tumors.

2. Internal Radiation Therapy (Brachytherapy)

Internal radiation therapy, or brachytherapy, involves placing a radioactive source directly inside or very close to the tumor. This method allows for a higher dose of radiation to be delivered to the cancer cells while reducing exposure to surrounding healthy tissue.

• Low-Dose Rate (LDR) Brachytherapy: This involves placing radioactive seeds in the tumor, which release radiation slowly over time.
• High-Dose Rate (HDR) Brachytherapy: In this method, a higher dose of radiation is delivered in a shorter time frame, often requiring multiple sessions.

3. Systemic Radiation Therapy

Systemic radiation therapy involves administering radioactive substances through the bloodstream, allowing them to target cancer cells throughout the body. This method is often used for cancers that have spread or for specific types of cancer, such as thyroid cancer.

• Radioactive Iodine Therapy: Commonly used for thyroid cancer, this treatment involves taking a pill or liquid that contains radioactive iodine.
• Radiolabeled Antibodies: These are antibodies that have been tagged with a radioactive substance, allowing them to target specific cancer cells.
