Symptoms of lung cancer explained as doctors admit disease isn't 'just for smokers'

Since its Lung Cancer Awareness Month, doctors are lifting the lid on the cruel disease and raising awareness to common symptoms.

According to the American Cancer Society, lung cancer is the leading cause of cancer death in the US, with an estimated 124,730 people to die from the cruel disease in 2025.

Catching it early is considered to be crucial when it comes to saving lives, with symptoms ranging from a lingering cough, fatigue and breathlessness.

Yet, there are many misconceptions surrounding its causes which can cause people to ignore these red flags.

Now, doctors are urging people to pay attention, particularly highlighting that lung cancer doesn't just impact smokers.

In fact, people who don't use tobacco products are still vulnerable due to air pollution and passive smoke as well as other genetic factors.

Dr. Anadi Pachaury, Associate Director and Unit Head of Surgical Oncology at Max Super Speciality Hospital, said in a report on the matter that some people can shrug off early warning signs in the colder months for flu or chest problems, reports Economic Times.

He warned people to watch out for a lingering cough that doesn't go away for weeks as well as a hoarse voice, shortness of breath, chest pain and/or feeling constantly tired.

Dr. Arun Kumar Goel added alarm bells should ring when a cough lasts more than three weeks, and could even show up in other ways like blood when coughing (in sputum), chest or back pain and frequent chest infections - even sudden weight loss can be a tell-tale sign.

The doctors said the signs are even more serious for smokers and people in polluted areas, though non-smokers can also contract lung cancer from inhaling smoke passively.

They explained that this is because cigarette smoke contains thousands of toxic chemicals which damage the DNA in lung cells, therefore causing cancer.

Longtime smokers and heavy smokers are at an increased risk, but they say the risk hikes no matter how much you smoke.

"The most powerful step to prevent lung cancer is to quit smoking completely—there’s no safe limit,” the pair said as per the report by TOI.

As for non-smokers, they advise to reduce exposure to air pollution by using clean fuel and air purifiers in the home.

Protective masks can also be used when out and about on high-pollution days.

The good news is that we can all work to keep our lungs healthy and happy through a good diet and regular exercise regime.

Dr Pachaury said green leafy vegetables, fruits and nuts would be a good start since they have antioxidants to protect cells, while steering clear of junk food and alcohol.

To add, Dr Goel said tumeric is also a good shout, as is exercise for 30 to 34 minutes every single day to help breathe better and improve the lungs.
