You might be curious to learn more about carcinoid tumours in the Lung Cancer  if you or someone you know has been diagnosed with one and how they differ from other types of lung cancer.

Lung cancers with carcinoid tumours are extremely uncommon. Carcinoid tumours make up only 1% to 2% of lung cancer cases. They often develop slowly. Since they are a specific kind of neuroendocrine tumour, they develop from the body’s particular neuroendocrine cells, which are located in the lungs and other parts of the body.

Lung Cancer Types

To receive the greatest care, it’s critical that you understand what form of carcinoid tumour you have. The two types of carcinoid tumours are typical and atypical.

The most typical carcinoid tumours are those. Approximately 90% of carcinoid Tumours are classified as normal. They often don’t spread outside of the lungs and they grow slowly.

Atypical carcinoid tumours have a faster rate of growth and a higher propensity to metastasis (spread) to organs other than the lungs.

According on where they are, lung carcinoid tumours are also referred to by doctors. Central carcinoids are tumours that develop in the walls of the major airways of the lungs. Peripheral carcinoids are those that are locate in the smaller airways towards the borders of your lungs.

The future is frequently bright. About 85% to 90% of persons with normal carcinoid lung tumours, as well as 50% to 70% of those with atypical carcinoids, continue to live for another 5 years or more.

Risk factors and the causes

The origins of lung carcinoid tumours are still largely unknown. They discover that while atypical carcinoid tumours are more common in smokers, conventional carcinoids do not appear to be related to smoking.

If you have any of the following:

  • Age. Carcinoid tumours can develop at any age, but they most frequently affect adults between the ages of 45 and 55.
  • Gender. Women experience carcinoid tumours more frequently than males do.
  • Race/ethnicity. White people experience these tumours more frequently than people of other races and ethnicities.
  • Family history. Your risk is higher if you have family members with carcinoid tumors.
  • Multiple endocrine neoplasia. This hereditary syndrome increases your risk of developing lung carcinoid tumours, pancreatic tumours, pituitary tumours, and Parathyroid tumours.

Symptoms Of Lung Cancer

You might be symptom-free. Most patients with these malignancies don’t—about 25% of them. When you undergo tests for another condition, your doctor might find them.

Lung carcinoid tumours may result in:

  • Coughing, occasionally with blood.
  • Wheezing
  • Chest ache
  • Breathlessness

Carcinoid syndrome is a disease that can occasionally be brought on by carcinoid tumours. That is a result of the hormones the cells in the tumours release. Flushing of the face and neck, diarrhoea, a rapid heartbeat, and weight gain are possible symptoms.


Your doctor will examine you and listen to your lungs while asking you questions about your medical history (which also includes family history).

Carcinoid tumours can be identify using these tests:

X-rays of the chest might reveal whether you have any lung tumours. Some might be too small or located in areas where normal X-rays can’t notice them.

A CT scan can provide you a cross-sectional view of your lungs and can also show you whether any cancers have spread to other organs like your liver.

Tests on the blood and urine may reveal compounds that carcinoid tumours occasionally emit. Blood levels of serotonin or chromogranin-A could indicate a typical carcinoid tumour. Your urine may contain traces of the serotonin byproduct 5-HIAA.

A biopsy is the process of removing a sample of tumour tissue to examine it under a microscope. There are two methods to do it. You’ll probably be anaesthetize if you undergo a nonsurgical biopsy. To examine the tissue, your doctor may introduce a bronchoscope, a kind of thin, flexible camera, into your lungs. You will require anaesthesia and a hospital stay if you undergo a surgical biopsy. Additionally, recovery time will be extended. In order to obtain the tissue sample, your doctor will need to make a few tiny surgical incisions in your chest.

Stages Of Lung Cancer

The size of your tumour and whether it has spread to surrounding lymph nodes or other areas of your body determine the stage of your cancer. Knowing the stage aids you in discussing treatment choices with your doctor.

The earliest stage is stage 0, while the most advance stage is stage IV. In order to further decompose it, doctors occasionally utilise letters in addition to the stage number.

Treatment Of Lung Cancer

Your doctor can explain to you the advantages and disadvantages of each of your treatment options and which one is most likely to benefit you.

Depending on your overall health, the location, type, stage, and atypicality of your lung tumours, surgery is typically the first option.

Following surgery, you can receive chemotherapy or radiation treatment. Your doctor might suggest targeted therapy, a specialised form of chemotherapy, if your tumours cannot be removed surgically, have spread, or have return. Everolimus  (Afinitor) was given FDA approval in 2016 for this use. Certain medications may limit the growth of your tumours and reduce the symptoms brought on by the hormones they emit.

If you find that alternative treatments aren’t a good fit for you, a clinical trial can be a possibility. Researchers investigate the efficacy and safety of novel medicines in clinical trials. Your doctor can assist you in finding a clinical study for which you could qualify. Before you sign up, make sure you are aware of everything that is involved, including the dangers, advantages, and the location of your treatment.
