A few words of thanks would be greatly appreciated.

Pulmonary lymphoma


Pulmonary lymphoma is a form of lung cancer. Some mild forms of lung infiltration by lymphocytes are possible. In its classic form, pulmonary lymphoma is an uncontrolled proliferation of cells of the lymphoid tissue and can develop directly in the cells of the lung, or be secondary to an invasion of the lung by other lymphomas. Generally, lymphoma affects patients whose immune system is weakened.


In most cases, lymphoma is asymptomatic. Cancer progresses silently, without the patient noticing. In other cases, it may be manifested by:
  • irritated breathing (dyspnea);
  • coughing;
  • chest pain;
  • the presence of blood in the sputum (hemoptysis).

Suggestive signs of lymphoma affecting another body may be present, such as an increase in the size of the spleen, liver or lymph nodes.


The diagnosis is made after a clinical examination. Additional tests are performed: chest radiography and a CT scan are frequent. On an X-ray, cancerous lesions may appear as opaque. The diagnosis is confirmed by a biopsy, usually taken during a bronchoscopy, which via the use of a mini camera introduced through the mouth, will help determine the type of tumor involved.


Treatment will depend on the type of lymphoma found, if it is primitive, or metastasized. Depending on the case, chemotherapy based on several drugs, and radiation are used, alone or in combination.
