Lung cancer is one of the most common cancers to be diagnosed in the UK, warned the NHS.
Around 45,000 people are diagnosed with lung cancer in the UK every year.
Signs of the disease only tend to reveal themselves once the cancer has spread through the lungs.
You could be at risk of lung cancer symptoms if you notice a blue or violet-coloured rash on your skin, it’s been revealed.
“Lung cancer causes several types of symptoms, including generalised, whole body symptoms such as fatigue and weight loss,” said the medical website.
“Lung cancer also causes symptoms from the invasion of the tumour into normal tissues, as well as symptoms related to various hormone-like compounds produced by the tumour. These processes can produce visible changes in the skin.
“The muscle weakness is progressive, and tends to occur in and around the hips and shoulders equally on both sides of the body.
“The rash is red to violet and may have blue patchy discolouration. It most commonly occurs over the eyelids and around the eyes, but may also occur on the hands, arms, legs and trunk.”
