Clinical Information

  • Lung masses are growths in the lungs that can be benign (noncancerous) or malignant (cancerous).
  • The causes of lung masses vary, ranging from infections and inflammation to various lung diseases, including cancer.
  • Symptoms associated with lung masses can vary, with some individuals exhibiting no symptoms. However, common symptoms can include chest pain, a persistent cough, and shortness of breath.
  • Diagnosing a lung mass typically involves imaging tests such as X-rays, CT scans, and PET scans. A biopsy may be performed for further analysis if necessary.
  • The treatment approach for a lung mass depends on the cause, size, and location of the mass, along with the patient's overall health. Treatment options may include monitoring, surgical removal, radiation therapy, or chemotherapy.
