Many patients with thymic tumors are asymptomatic and their tumors are discovered incidentally during imaging for other reasons. When symptoms do occur, they may include:
Chest pain Cough Shortness of breath Hoarseness Swelling of the face, neck, or upper limbs
Additionally, due to the thymus' role in the immune system, thymic tumors are often associated with paraneoplastic syndromes, such as myasthenia gravis, which can cause muscle weakness and fatigue.
