Why do People Get Lung Cancer? The Most Common Causes Revealed

Due to the coronavirus pandemic, more of us are thinking about our health. What we eat, how much we exercise and our lifestyle choices have all come into question since we’ve had our mortality highlighted due to the spread of the virus.

Despite COVID-19 being a new threat to our health, for many, the threat of developing cancer is still a considerable concern. There are many different types of cancer, with the most common being prostate, breast, skin, and of course lung cancer. Thanks to advances in technology and the constant evolution of medical understanding around cancers, we no longer have to consider cancer as a death sentence. With new treatments being used all the time and cancers being caught much earlier, more people are surviving than ever before.

Lung cancer is the most common cancer, and sadly many people still aren’t aware of the signs or even what can trigger this devastating disease to develop – click the link to learn more and to find a lung cancer lawyer.

So, with this in mind here we’ll explore why people might develop lung cancer and discuss the most common causes.

Workplace Risks

If you work in an industrial type role, or you’re dealing with harsh substances then you’re more likely to be exposed to the chemicals that can trigger lung cancers.

If you work with fuel engines and you spend most of your time exposed to exhaust fumes (like drivers or a mechanic might) then you could be at a higher risk. Working with substances such as silica – often used in glassmaking and bricklaying – can also increase your risk. And anyone who is working with asbestos – even in old buildings – can increase their chances of developing lung cancers.


Of course, we all know that smoking can cause lung cancer and it's hardly surprising. Around 7 out of 10 lung cancer diagnoses are smoking-related. The chemicals found in tobacco smoke such as ammonia, carbon monoxide and hydrogen cyanide (yes, cyanide) increase your risk of triggering lung cancer development. Even if you're just passively smoking, you're still increasing your risk and harming your health. If you haven’t already, quit!

Air Pollution

We're all familiar with how pollutants in the air are damaging our environment. But did you also know that air pollution can be incredibly damaging to your health? Of course, the risks associated with air pollution and lung cancer are quite minimal, but it's not unheard of and should be taken seriously.

Your Family History

Some cancers, including lung cancer, can be hereditary, which means if your family has a history of lunch cancer, then you could be at risk. If you have a close relative that has battled the disease then you should take additional steps to preserve your health. Recognizing the early signs of lung cancer will also help you.
