A lung NET is a rare form of lung cancer. Some doctors may refer to a lung NET as a bronchial NET.

There are many subtypes of lung NETs, some of which are slow growing, while others may grow more rapidly.

Lung NET Symptoms You May Have

A lung NET usually causes symptoms such as coughing and wheezing. Because these symptoms are common or similar to symptoms that are associated with other diseases, it may take a long time for doctors to diagnose a lung NET.

There are different types of lung NET, which are grouped into the following categories:

• Low-grade, typical carcinoid

• Intermediate-grade, atypical carcinoid

• High-grade, small cell lung carcinoma (SCLC)

• High-grade, large cell neuroendocrine carcinoma (LCNEC)

Common signs and symptoms of a lung NET:

• Chronic cough

• Chest pain

• Shortness of breath

• Coughing up blood

• Wheezing

Recurrent and Progressive Disease

Depending on the type of lung NET, after the tumor has been surgically removed, the disease returns and/or metastasizes in 30% to 40% of patients. A lung NET that has become metastatic can spread to the liver or bones or other areas. Therefore, it is important to consult your doctor, who can order scans and do other follow-up exams on a regular basis.
