ON THIS PAGE: You will find out more about changes and other things that can signal a problem that may need medical care. Use the menu to see other pages.

People with thymoma or thymic carcinoma may experience the following symptoms or signs. Symptoms are changes that you can feel in your body. Signs are changes in something measured, like by taking your blood pressure or doing a lab test. Together, symptoms and signs can help describe a medical problem. Sometimes, people with thymoma or thymic carcinoma do not have any of the symptoms and signs described below. Or, the cause of a symptom or sign may be a medical condition that is not cancer.

  • Persistent cough

  • Shortness of breath

  • Pain or pressure in the chest

  • Muscle weakness

  • Drooping eyelids

  • Double vision

  • Arm or facial swelling

  • Difficulty swallowing

  • Anemia, which is a low red blood cell count

  • Frequent infections

  • Fatigue

  • Dizziness

If you are concerned about any changes you experience, please talk with your doctor. Your doctor may ask how long and how often you have been experiencing the symptom(s), in addition to other questions. This is to help figure out the reason for the symptoms, called a diagnosis.

If cancer is diagnosed, relieving symptoms remains an important part of cancer care and treatment. Managing symptoms may also be called "palliative care" or "supportive care." Be sure to talk with your health care team about the symptoms you experience, including any new symptoms or a change in symptoms.
