What are Lung NETs?

NETs is the shortened name for “neuroendocrine tumors”. This type of can start to grow in different places in the body. NETs are different from other types of tumors, because they grow in cells that produce hormones.

Because the tumors affect hormones, the symptoms of NETs can be very different depending on where in the body the NET is in. Not all NETs are cancerous, but some are.

NETs grow very slowly, and it sometimes takes years for them to form. The earlier they are spotted, the better are the chances for recovery.

If the NETs are found in the lungs, the condition is called either Lung NETs, Bronchial NETs, or Pulmonary NETs.

What are the symptoms of Lung NETs?

The symptoms of Lung NETs can be very difficult to link to the particular disease. Since the tumors grow in cells that produce hormones, the symptoms can be different depending on exactly where the tumor is. Sometimes, there are no symptoms at all.

Some symptoms of Lung NETs that might show are coughing, wheezing, issues with breathing and pains in the chest area.

It’s important to remember that these symptoms most likely is the cause of something that is not Lung NETs, but it’s always good to get checked out by your doctor.

What causes Lung NETs?

Doctor’s are not sure what exactly causes Lung NETs. There are, however, some factors that can increase the risk of Lung NETs. For example, if there are family members who’ve had Lung NETs, the risk is higher.

Also, old age and already existing diseases seem to have an impact on the risks of getting Lung NETs. Research has for example shown that people who suffer from Cushing’s disease have a higher risk of getting Lung NETs.

It’s important to remember that these are only risk factors, and that they don’t automatically mean a Lung NET diagnosis. Always consult a doctor if there are any concerns.  

How can Lung NETs be treated?

There are different treatment options for Lung NETs. Which treatment works best depends on if the tumor is cancerous or not, how much it has spread, and where it’s located.

If the NETs are small and haven’t spread too much, they can often be surgically removed. If the NETs have spread and are cancerous, surgery is often not the best option. Usually, chemotherapy in combination with radiotherapy is used in those cases.

Are there clinical trials for Lung NETs?

Yes, a clinical trial for Lung NETs has recently been launched, mainly looking for participants across the Unites States. Read more about it here:
