Schamroth window: Simple finger test that ‘can reveal cancer’

Lung cancer is one of the most common and serious types of cancer. 

Around 47,000 people are diagnosed with the condition every year in the UK.

There are usually no signs or symptoms in the early stages of lung cancer, but many people with the condition eventually develop symptoms including:

– a persistent cough

– coughing up blood

– persistent breathlessness

– unexplained tiredness and weight loss

– an ache or pain when breathing or coughing

You should see a GP if you have these symptoms.

Types of lung cancer 

There are two main forms of primary lung cancer. 

These are classified by the type of cells in which the cancer starts growing. 

They are:

– Non-small-cell lung cancer. The most common form, accounting for more than 87 per cent of cases. 

– It can be one of three types: squamous cell carcinoma, adenocarcinoma or large-cell carcinoma.

– Small-cell lung cancer – a less common form that usually spreads faster than non-small-cell lung cancer.

– The type of lung cancer you have determines which treatments are recommended.

Who’s affected

Lung cancer mainly affects older people. It’s rare in people younger than 40. 

More than four out of 10 people diagnosed with lung cancer in the UK are aged 75 and older.

Although people who have never smoked can develop lung cancer, smoking is the most common cause (accounting for about 72 per cent of cases). 

This is because smoking involves regularly inhaling a number of different toxic substances.

Treating lung cancer

Treatment depends on the type of mutation the cancer has, how far it’s spread and how good your general health is.

If the condition is diagnosed early and the cancerous cells are confined to a small area, surgery to remove the affected area of lung may be recommended.

If surgery is unsuitable due to your general health, radiotherapy to destroy the cancerous cells may be recommended instead.

If the cancer has spread too far for surgery or radiotherapy to be effective, chemotherapy is usually used.

There are also a number of medicines known as targeted therapies. 

They target a specific change in or around the cancer cells that is helping them to grow. 

Targeted therapies cannot cure lung cancer but they can slow its spread.
