Lung Cancer

Lung cancer is one of the most common types of cancer, claiming more lives each year than any other type.1 There are many subtypes of lung cancer but broadly lung cancer is divided into two types; non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). As 80% of lung cancers are caused by tobacco exposure, many people with lung cancer also experience stigma and disapproval from others.2 

What is Lung Cancer?

Of the two main types of lung cancer, NSCLC and SCLC, approximately 80-85% of lung cancer cases are classified as NSCLC, while the remaining 15-20% are SCLC.3

Symptoms and diagnosis of lung cancer

People may not always experience lung cancer symptoms early on and so it might be diagnosed only by chance when being tested for a different condition. Common symptoms include:4

  • Persistent cough lasting three weeks or more
  • Changes in a chronic cough
  • Recurrent or non-resolving chest infections
  • Unexplained breathlessness and wheezing
  • Coughing up blood
  • Hoarse voice lasting three weeks or more

Other possible symptoms are:

  • Loss of appetite
  • Losing weight for no obvious reason
  • Feeling tired.

A diagnosis for lung cancer often begins with imaging tests such as MRI, CT scans, bone scans, and PET scans.5 

When it comes to treatment, this will depend on the type and stage of lung cancer and healthcare teams will consider the overall health of the person living with lung cancer, as well as their preferences.5
