Mesothelioma is a form of cancer that is caused by prolonged exposure to asbestos. It is a rare but aggressive type of cancer that affects the lining of the lungs, heart, or abdomen. Mesothelioma treatment typically includes a combination of surgery, chemotherapy, and radiation therapy.
Introduction
According to the American Cancer Society, radiation therapy is one of the most common treatments for mesothelioma. Radiation therapy uses high-energy radiation to kill cancer cells and shrink tumors. There are several types of radiation therapy that may be used to treat mesothelioma, including external beam radiation therapy, internal radiation therapy, and intensity-modulated radiation therapy.
In this article, we will discuss the different types of radiation therapy used to treat mesothelioma, their benefits and risks, and how to choose the right treatment for you.
What is Mesothelioma?
Mesothelioma is a type of cancer that affects the mesothelium, which is a thin layer of tissue that covers the organs in the body. Mesothelioma is caused by exposure to asbestos, a mineral that was once widely used in construction, insulation, and other industries.
Some common symptoms of mesothelioma include difficulty breathing, chest pain, coughing, and weight loss. Unfortunately, mesothelioma is often diagnosed in its late stages, which makes it difficult to treat.
What is Radiation Therapy?
Radiation therapy is a type of cancer treatment that uses high-energy radiation to kill cancer cells and shrink tumors. Radiation therapy may be used alone or in combination with other treatments, such as surgery or chemotherapy.
Radiation therapy works by damaging the DNA inside cancer cells, which prevents them from dividing and growing. Radiation therapy can be delivered from outside the body (external beam radiation therapy) or from inside the body (internal radiation therapy).
Types of Radiation Therapy
There are several types of radiation therapy that may be used to treat mesothelioma, including:
1. External Beam Radiation Therapy
External beam radiation therapy (EBRT) is the most common type of radiation therapy used to treat mesothelioma. EBRT uses a machine called a linear accelerator to deliver radiation to the tumor from outside the body.
EBRT may be used to treat mesothelioma before or after surgery, or as a palliative treatment to relieve symptoms. EBRT is typically delivered over a period of several weeks, with each treatment session lasting about 15-30 minutes.
2. Internal Radiation Therapy
Internal radiation therapy, also known as brachytherapy, involves placing radioactive material inside the body near the tumor. The radiation is delivered directly to the tumor, which reduces the risk of damage to healthy tissue.
Internal radiation therapy may be used to treat mesothelioma in the chest or abdomen. It is typically delivered over a period of several days or weeks.
3. Intensity-Modulated Radiation Therapy
Intensity-modulated radiation therapy (IMRT) is a type of EBRT that uses computer-controlled beams to deliver radiation to the tumor. IMRT allows for more precise targeting of the tumor, which reduces the risk of damage to healthy tissue.
IMRT may be used to treat mesothelioma before or after surgery, or as a palliative treatment to relieve symptoms. IMRT is typically delivered over a period of several weeks, with each treatment session lasting about 15-30 minutes.
Benefits and Risks of Radiation Therapy for Mesothelioma
Radiation therapy can be an effective treatment for mesothelioma, but it also comes with risks and side effects. Some potential benefits of radiation therapy for mesothelioma include:
- Shrinkage of tumors
- Reduced symptoms, such as pain and difficulty breathing
- Improved quality of life
However, radiation therapy can also cause side effects, such as:
- Fatigue
- Skin irritation
- Nausea and vomiting
- Diarrhea
- Hair loss
In rare cases, radiation therapy can also cause more serious side effects, such as lung damage or heart problems. Your healthcare team will monitor you closely during and after treatment to ensure that any side effects are managed appropriately.
Choosing the Right Type of Radiation Therapy for You
The type of radiation therapy that is best for you will depend on several factors, including the size and location of your tumor, your overall health, and your personal preferences. Your healthcare team will work with you to choose the treatment that is most likely to be effective while minimizing the risk of side effects.
Table 1: Comparison of Types of Radiation Therapy for Mesothelioma
| Type of Radiation Therapy | How it Works | Benefits | Risks and Side Effects |
|---|---|---|---|
| External Beam Radiation Therapy | High-energy radiation is delivered to the tumor from outside the body. | Shrinkage of tumors; reduced symptoms; improved quality of life. | Fatigue, skin irritation, nausea and vomiting, diarrhea, hair loss. |
| Internal Radiation Therapy | Radioactive material is placed inside the body near the tumor. | More precise targeting of the tumor; reduced risk of damage to healthy tissue. | Fatigue, skin irritation, nausea and vomiting, diarrhea, hair loss. |
| Intensity-Modulated Radiation Therapy | Computer-controlled beams deliver radiation to the tumor. | More precise targeting of the tumor; reduced risk of damage to healthy tissue. | Fatigue, skin irritation, nausea and vomiting, diarrhea, hair loss. |
Frequently Asked Questions
1. Does radiation therapy hurt?
Radiation therapy itself is painless, but it can cause some discomfort and side effects. Your healthcare team will work with you to manage any discomfort you may experience during treatment.
2. Will radiation therapy make me radioactive?
No, radiation therapy will not make you radioactive. The radiation is delivered externally or internally, and it does not stay in your body after treatment.
3. How long does radiation therapy take?
Radiation therapy is typically delivered over a period of several weeks, with daily treatments lasting about 15-30 minutes each. Your healthcare team will provide you with a treatment schedule that outlines the exact number and duration of treatments you will receive.
4. Can I work during radiation therapy?
Many people are able to continue working while undergoing radiation therapy, but it will depend on your individual circumstances. Your healthcare team can provide guidance on whether you should take time off work during treatment.
5. What can I do to manage side effects of radiation therapy?
There are several strategies you can use to manage side effects of radiation therapy, including eating a healthy diet, getting plenty of rest, staying hydrated, and taking medications as prescribed. Your healthcare team can provide specific recommendations for managing the side effects you experience.
6. How effective is radiation therapy for mesothelioma?
Radiation therapy can be an effective treatment for mesothelioma, especially when used in combination with other treatments like surgery and chemotherapy. The effectiveness of radiation therapy will depend on several factors, including the size and location of your tumor and your overall health.
7. Are there any long-term side effects of radiation therapy for mesothelioma?
In rare cases, radiation therapy can cause long-term side effects like lung damage or heart problems. Your healthcare team will monitor you closely during and after treatment to detect any signs of long-term side effects.
Conclusion
Radiation therapy can be a valuable tool in the fight against mesothelioma. By understanding the different types of radiation therapy available and their benefits and risks, you can make an informed decision about your treatment plan. If you have mesothelioma, talk to your healthcare team about whether radiation therapy may be right for you.
Remember, early detection is key when it comes to mesothelioma. If you have been exposed to asbestos in the past, be sure to tell your healthcare provider so that they can monitor you for symptoms and detect mesothelioma early if it does develop.
Closing
We hope this article has provided you with a better understanding of the different types of radiation therapy used to treat mesothelioma. If you have any questions or concerns about your treatment plan or mesothelioma, don’t hesitate to reach out to your healthcare team.
