Mesothelioma Radiation Effects: Understanding the Impact of Radiation Therapy

Mesothelioma is a rare and aggressive form of cancer that affects the mesothelium, a thin layer of tissue that covers most internal organs. Exposure to asbestos is the primary cause of mesothelioma, and it can take years, even decades, for the cancer to develop. While there is no cure for mesothelioma, radiation therapy can be effective in managing symptoms and improving quality of life for patients. However, radiation therapy also comes with its own set of side effects and potential risks that patients should be aware of before undergoing treatment.

What is Radiation Therapy?

Radiation therapy is a commonly used treatment technique for mesothelioma, which uses high-energy radiation to kill cancer cells in the affected area. The radiation can be delivered either externally, using a machine that directs radiation beams at the cancer cells from outside the body, or internally, by placing radioactive material directly into the tumor cells. Radiation therapy can be given alone or in combination with other treatments such as chemotherapy and surgery, depending on the stage and location of the cancer.

How does Radiation Therapy Work?

Radiation therapy works by damaging the DNA of the cancer cells, preventing them from dividing and growing. Normal cells in the area may also be affected by the therapy, but they can recover more easily than cancer cells. The radiation dose and duration of treatment are carefully calculated to minimize damage to healthy cells while effectively treating the cancer. The goal of radiation therapy for mesothelioma is usually to alleviate symptoms such as pain and shortness of breath, rather than aiming for a complete cure.

Types of Radiation Therapy

External Radiation Therapy Delivers radiation beams from outside the body using a machine such as a linear accelerator. The machine can be adjusted to deliver radiation at different angles to target the cancer cells while minimizing damage to surrounding tissues.
Internal Radiation Therapy Also known as brachytherapy, involves placing radioactive material directly into the tumor cells using a catheter or other device. This method allows for a higher radiation dose in the affected area, while minimizing exposure to healthy tissues.
Systemic Radiation Therapy Uses a radioactive substance that is injected into the bloodstream and travels throughout the body to target cancer cells. This method is less commonly used for mesothelioma.

Side Effects of Radiation Therapy

While radiation therapy can be effective in treating mesothelioma, it can also cause side effects that vary depending on the type and extent of radiation used, as well as the patient’s overall health. Common side effects of radiation therapy for mesothelioma include:

  • Fatigue
  • Skin irritation and redness
  • Nausea and vomiting
  • Loss of appetite
  • Shortness of breath
  • Swelling and inflammation of the affected area
  • Increased risk of infection

Some side effects may be immediate and short-lived, while others may develop over time and persist after treatment has ended. Patients may work with their healthcare team to manage side effects and improve their quality of life during and after treatment.

Long-Term Risks of Radiation Therapy

While radiation therapy can be an effective treatment for mesothelioma, it also comes with its own set of risks and potential long-term effects. These risks may include:

  • Radiation pneumonitis, or inflammation of the lungs
  • Radiation fibrosis, or scarring of the lung tissue
  • Damage to other organs in the affected area
  • Increased risk of developing a secondary cancer
  • Damage to healthy tissues and cells

Patients should discuss the potential risks and benefits of radiation therapy with their healthcare team before undergoing treatment, and weigh the options based on their individual situation and goals of care.
