How to spot lung cancer early

One of the reasons lung cancer is so dangerous is because the symptoms are vague and often aren't severe until the cancer is in its late stages. Here's how to spot it as early as possible.

UK survival rates are poor compared with the rest of Europe and the US.

Only 9% of people with lung cancer in the UK survive for at least five years compared with 12.3% in Europe and 15% in the US. Many people don't realise that if lung cancer is detected earlier, it can be cured.

Experts believe that the poor survival rate in the UK is partly because people don’t recognise that their symptoms could be serious. They don't get help until it’s too late.

More than two thirds of lung cancers are diagnosed at a late stage when the likelihood of survival is reduced.

Some smokers feel they shouldn't bother their GP when they have symptoms that may be caused by smoking. For this reason they can be reluctant to go to the doctor.

Many lung cancers spread quickly and can grow to quite a large size if they’re not detected, so it’s vital to recognise warning signs early and get medical attention promptly.

Lung cancer can be cured, and this is more likely if it’s caught early.

If you have any of the following symptoms, especially if you smoke or have been a smoker, see your GP as soon as possible:

  • A cough that doesn't go away after three weeks.
  • Coughing more often and more severely than usual.
  • Coughing up blood.
  • Shortness of breath.
  • Feeling weak or more tired than usual.
  • Losing weight without knowing why.
  • Pain in the ribcage and/or shoulder.
  • Chest infections that won’t go away, even with antibiotics.
  • Hoarseness.
  • Swelling of the face and neck. 

These symptoms may not be serious, in which case you’ve got nothing to lose by getting them checked. If they are serious, you’ve got everything to gain. Diagnosis at an early stage could save your life. 

There are many places you can get help:

Screening for lung cancer

The search is on for a screening test for people at high risk of lung cancer (such as heavy smokers, ex-smokers and people exposed to asbestos) that can diagnose the disease at an early stage, even before symptoms have appeared. 

At the moment, lung cancer is usually identified on a chest X-ray. This is a valuable test in many patients but it's not reliable for detecting tumours in their early stages.

Researchers are trying to find a reliable test to detect early disease. So far, there are two possibilities: low-dose radiation computed tomography (CT) scanning, and new ways of examining the sputum (spit) combined with an advanced type of bronchoscopy (looking into the airway with an instrument). Both tests are currently being trialled in thousands of people.

Lung cancer awareness

At the launch of Lung Cancer Awareness Month, Gary Lineker and former patients talk in this video about why it's important to be aware of symptoms.
