Introduction: Understanding Mesothelioma and PET Scans
Welcome to our article about PET scans and mesothelioma in the lungs. We understand that receiving a diagnosis can be overwhelming, and we hope this article can help. Mesothelioma is a type of cancer that affects the lining of organs, commonly the lungs. PET scans are a diagnostic tool that can detect cancer by creating images of the body’s metabolic activity. In this article, we will dive into the details of PET scans and mesothelioma, including how they work and what to expect during the procedure.
What is Mesothelioma?
Mesothelioma is a rare form of cancer that develops in the lining of the chest, abdomen, or heart. It is caused by exposure to asbestos, a mineral used in construction, shipbuilding, and other industries from the 1940s to the 1970s. Asbestos fibers can become lodged in the lungs, causing inflammation and scarring. These fibers can eventually lead to the development of mesothelioma, which can take up to 50 years to develop after exposure. Symptoms of mesothelioma in the lungs include chest pain, shortness of breath, coughing, and fatigue.
What is a PET Scan?
A PET scan, or positron emission tomography scan, is a diagnostic tool that creates images of the body’s metabolic activity. During a PET scan, a small amount of radioactive tracer is injected into the body. This tracer travels to areas of high metabolic activity, such as cancerous cells. The tracer emits positrons, which can be detected by a PET scanner. The scanner creates images of the body’s metabolic activity, which can help doctors detect cancer and monitor treatment progress.
How Does a PET Scan Work?
During a PET scan, the patient lies on a table that slides into the PET scanner. The scanner detects the positrons emitted by the radioactive tracer and creates images of the body’s metabolic activity. The procedure usually takes around 30 minutes to an hour, and the patient may need to fast beforehand. Patients should also inform their doctor of any medications they are taking before the procedure.
What to Expect During a PET Scan for Mesothelioma in the Lungs?
Prior to the scan, patients will need to remove any metal objects, such as jewelry or belts, as well as wear a hospital gown. The patient may also need to fast for several hours before the scan. During the scan, the patient lies on a table that slides into the PET scanner. The scanner will create images of the body’s metabolic activity, which can help identify cancerous cells. After the scan, patients can typically resume normal activities.
How Accuracy is PET Scans in Detecting Mesothelioma in the Lungs?
PET scans are highly accurate in detecting mesothelioma in the lungs. According to a study published in the Journal of Clinical Oncology, PET scans have a sensitivity of 93% and a specificity of 96% in detecting mesothelioma. This means that PET scans are highly effective in detecting mesothelioma, and can also help differentiate it from other types of cancer or non-cancerous conditions.
Can PET Scans Detect Mesothelioma in the Early Stages?
Yes, PET scans can detect mesothelioma in the early stages. In fact, early detection is crucial for improving mesothelioma prognosis. According to a study published in the Annals of the American Thoracic Society, PET scans were effective in detecting early-stage mesothelioma in patients with a history of asbestos exposure. The study found that PET scans detected early-stage mesothelioma in 80% of patients, while chest x-rays only detected it in 26% of patients.

Frequently Asked Questions
How is mesothelioma treated?
Mesothelioma is typically treated with a combination of surgery, chemotherapy, and radiation therapy. Treatment options may vary depending on the stage and location of the cancer.
What is the prognosis for mesothelioma in the lungs?
The prognosis for mesothelioma in the lungs is generally poor, with a five-year survival rate of less than 10%. Early detection and treatment can improve prognosis.
Can mesothelioma be cured?
Currently, there is no cure for mesothelioma. However, early detection and treatment can help improve prognosis and quality of life.
What is the difference between a CT scan and a PET scan?
A CT scan creates detailed images of the body’s internal structures using X-rays, while a PET scan creates images of the body’s metabolic activity. PET scans are often used in conjunction with CT scans to help diagnose and monitor cancer.
What if my PET scan shows mesothelioma in the lungs?
If your PET scan shows mesothelioma in the lungs, your doctor may recommend further testing or treatment. It is important to discuss your options with your doctor and ask any questions you may have.
How long does it take to receive PET scan results?
It typically takes a few days to receive PET scan results. Your doctor will discuss the results with you and recommend any necessary next steps.
Can PET scans detect other types of cancer?
Yes, PET scans can detect many types of cancer, including lung cancer, breast cancer, and lymphoma.
Are PET scans covered by insurance?
Most insurance plans cover PET scans for cancer diagnosis and monitoring, but coverage may vary depending on the plan and specific circumstances.
Do I need to prepare for a PET scan?
Patients may need to fast for several hours before a PET scan and remove any metal objects. Patients should also inform their doctor of any medications they are taking.
Is a PET scan safe?
PET scans are generally safe and have few risks. Patients may be exposed to a small amount of radiation, but the benefits of the scan usually outweigh the risks.
Can PET scans replace biopsies?
No, PET scans cannot replace biopsies, which are necessary for definitive cancer diagnosis. PET scans can help identify areas of concern and guide biopsy placement.
How often should I have a PET scan for mesothelioma?
The frequency of PET scans for mesothelioma will depend on the stage and treatment of the cancer. Your doctor will recommend a schedule for monitoring mesothelioma progression and response to treatment.
Can I drive myself home after a PET scan?
Yes, patients can typically drive themselves home after a PET scan, but they may feel tired or groggy from the procedure. Patients should arrange for transportation if they do not feel well enough to drive.
What should I wear for a PET scan?
Patients should wear comfortable clothing and avoid wearing any metal objects, such as jewelry or belts, that may interfere with the scan.
