Lung cancer symptoms don’t usually become apparent until the tumour has grown. While many of the symptoms can be mistaken for less serious conditions, any signs should be taken seriously. This is because lung cancer is one of the most common types of cancer in the UK, as well as one of the most serious. A cough is one of the most common signs of the disease, as well as feeling breathless, and chest or shoulder pain.
But there are three other symptoms to take note of that aren’t usually associated with lung cancer, according to Macmillan.
- Losing weight for no obvious reason
- Feeling extremely tired (fatigue)
- The ends of fingers change shape – they may become larger or rounded (clubbing)
The cancer charity adds: “If you have any of these symptoms, it’s important to have them checked by your GP.
“Some of these symptoms can be caused by other conditions or by smoking.
“Lung cancer is occasionally diagnosed by chance when a person is having tests for another condition.
“In this situation, the cancer is more likely to be at an early stage.”
While a cough is one of the most common symptoms of lung cancer, they can also be caused by smoking, heartburn, allergies and infections.
So how do you know if your cough is linked to lung cancer? There are three signs to look out for, according to Cancer Research UK.
- It may be more painful
- It may have a different sound
- It may bring up coloured mucus or phlegm
