Lung cancer is one of the biggest killers in the world. Lung cancers often spread more quickly than other forms of cancer, with cancer cells spreading through the blood that runs through the lungs and travels to the rest of the body. This often means that lung cancer is detected only after spreading. While there are treatments available, very often, early detection offers the best possible chance for successful treatment. Spotting the signs early is therefore the key. However, to spot the signs, you first have to know what they are.
Here are the 7 signs to look out for.
- Bloating
If you have had unexplained bloating for 3 weeks or more, it is definitely time to consult the advice of a medical professional.
2. Changes in your bowel movements
If you have sustained constipation, diarrhea, blood in your stools, or any other irregularity, it is best to get this checked out with a doctor.
3. Unexplained and rapid weight loss
If you rapidly lose weight without any corresponding change to your diet or exercise regime, it might be time to consult your GP.

4. Coughing, Chest Pains or shortness of breath
If you have a sustained cough, chest pains, or shortness of breath, consult a medical professional as soon as possible.
If the tumour is obstructing the airways it may also cause shortness of breath, wheezing, and a persistent cough that may include blood and phlegm.
5. Fatigue and chronic tiredness
In some cases, a lung tumour might release large amounts of hormones that cause symptoms further away in the body.
6. Chronic lung infections
Lung cancer can coincide with other lung infections. If you have a lung infection that is not responding to antibiotics or other treatments your doctor might investigate for lung cancer.

7. Pain in limbs
A tumour located at the top of the lung can create pressure on nerves and blood vessels going into the arm, causing pain and weakness of the limbs.
