Cancerous tumours form when a group of cells in the body begin to reproduce at an uncontrollable rate. This can prohibit normal cells from functioning properly, and the body begins to malfunction.
Providing details on the lungs is the American Cancer Society, who explained the difference between this pair of organs.
The right lung has three parts called lobes, while the left lung has two lobes.
The left lung is smaller (with only two lobes) as it needs to accommodate for the size of the heart, which is angled slightly to the left of the body.
However, how do you know if it’s a smoker’s cough, a sign of chronic obstructive pulmonary disease or lung cancer?
Simply put, you can’t – that’s the blunt answer put forward by Medical News Today.
This fact highlights the importance of regular medical check-ups, particularly for smokers.
The Cancer Treatment Centres of America highlighted other key warning signs of lung cancer.
For example, chest pain that gets worse with deep breathing, laughing or coughing can be indicative of lung cancer.
Another symptom of the condition is unexplained loss of appetite and weight.
The voice may sound hoarse, you could be wheezing, and feel weak or tired.
In terms of coughing, you may cough up blood or rust-coloured phlegm, and suffer from shortness of breath.
Second-hand smoke is also highly linked to the development of the disease.
Staying away from tobacco smoke (and quitting if you do partake in the activity) is highly recommended to lower your chances of lung cancer.
Another culprit is radon gas – odourless, it can be found in some homes.
