Small-cell lung cancer

In SCLC, the cancer cells are small cells that are mostly filled with the nucleus (the control centre of cells).

The cancer usually starts in the cell lining of the trachea or bronchi. As this type of lung cancer can spread quickly, it is often found to have spread at the time it is diagnosed.

Symptoms of lung cancer

Lung cancer often has no symptoms in the early stages of the disease.

A cough is usually the first symptom of lung cancer in most people. swollen lymph nodes (lymph nodes are part of the body's immune system)

Causes of lung cancer

Many of the causes of lung cancer are unknown but there are certain factors that make lung cancer more likely, which are listed below.

Smoking - most lung cancers are smoking-related. Smokers are at much greater risk of getting lung cancer and passive smoking has also been linked to lung cancer. Chemicals - exposure to chemicals such as asbestos increases the risk of lung cancer.

Diet - some studies have shown a diet low in fruit and vegetables may contribute to an increased risk of developing lung cancer.

Diagnosis of lung cancer

A CT scan (computerised tomography) can be useful for detecting non-small-cell tumours and can help your doctor see how far the cancer has spread (if at all). Ask your doctor for more information.
