If shortness of breath happens after exercise activities note if you have a wheezing (high-pitched whistling sound) noise when breathing. This can be asthma. [3] X Research source

If you have acid reflux from spicy, fatty, or acidic foods, it can lead to a chronic cough. If altering your diet reduces the cough, then it isn’t likely a thymoma.

National Institutes of Health Go to source If you live in or have traveled to an area with tuberculosis (TB) and have experienced a chronic cough, bloody sputum (blood mucus coughed up), night sweats, and a fever, then you may have TB for which you should still see a doctor immediately.

If you feel pressure-like chest pain and have sweating, palpitations (feel like your heart is jumping out of your chest), fever, or chest pain when moving or breathing, then you may have an underlying lung or heart disease.

If you experience unintentional weight loss without any known reason, check with your healthcare provider. Many cancers have weight loss as a symptom.

Swelling of the face, neck, and upper body. Note if the upper part of your body looks more red or flushed. Dilated veins in the upper body. Look at the veins in your arms, hands, and wrist to see if they look more prominent or dilated. These are usually the dark lines or tunnels we see on the hands and arms. Headaches due to dilated veins supplying the brain. Dizziness/light headedness. Because blood is backed up, the heart and brain receive less oxygenated blood. When your heart pumps less blood to the brain or when your brain doesn’t receive enough oxygenated blood, you feel light headed or dizzy and may fall. Laying down helps remove the force of gravity your blood has to fight to supply your brain.

MRIs are very loud and some are closed meaning that you will be inserted lying down in a large cylindrical space. This can give the sensation of claustrophobia (fear of enclosed spaces) to some people. The test may take up to an hour to complete.

Doctors use combined PET/CT scans more often than PET scans alone when looking at thymomas. This lets the doctor compare areas of higher radioactivity on the PET scan with the more detailed images on the CT scan.

If you are taking blood thinners (coumadin/warfarin), your doctor may ask you to stop days before the exam and not to eat or drink the day of the procedure.

The exam preparation (fasting, etc. ) is similar to that of a needle biopsy, except an incision will be made in the skin to gain access to the tumor to remove it.

Stage I is an encapsulated tumor without microscopic or gross invasion. Surgical excision is the treatment of choice Stage II is a thymoma with a macroscopic invasion of the mediastinal fat or pleura or the microscopic invasion of the capsule. Treatment is usually a complete excision with or without postoperative radiation therapy in order to reduce the incidence of recurrence. Stage III is when the tumor has invaded the lungs, great vessels, and the pericardium. Complete surgical excision is necessary together with postoperative radiation therapy so that recurrence will not occur. Stage IVA and IV B In these final stages, there is pleural or metastatic spread. The treatment is a combination of surgical debulking, radiation, and chemotherapy.
