When it involves lung cancer, there’s a frequent false impression that it will possibly solely have an effect on sure folks, similar to those that are older or these with a historical past of smoking.
However, the query in relation to lung cancer is now not simply “Do you smoke?”.
The actuality is {that a} non-smoker who lives a wholesome way of life will be identified with lung cancer too.
While smoking stays the most typical reason behind lung cancer in Malaysia, the variety of non-smokers being identified with this cancer has been rising in recent times, in response to the expertise of medical practitioners in Malaysia.
“Up to a third of the patients we see with confirmed lung cancer are non-smokers or never smokers,” says marketing consultant cardiothoracic surgeon and Lung Cancer Network Malaysia (LCNM) president Dr Anand Sachithanandan.
For senior marketing consultant scientific oncologist and LCNM vice-president Dr Tho Lye Mun, half his lung cancer sufferers are non- or very gentle people who smoke, and surprisingly, most of them are girls.
Family and air pollution
Aside from smoking, an individual can be in danger for lung cancer if they’ve a historical past of lung cancer within the household.
A scientific trial carried out in Taiwan between February 2015 and July 2019 discovered that a person’s lung cancer danger will increase with the variety of first-degree relations with lung cancer they’ve.
According to Dr Tho, the atmosphere we dwell in poses dangers too.
If you might be continually uncovered to secondhand smoke from people who smoke round you or in case you are continuously uncovered to asbestos at work, your possibilities of getting identified with lung cancer will probably be larger.
In reality, the World Health Organization (WHO) just lately confirmed a regarding hyperlink between air air pollution and lung cancer.
The International Agency for Research on Cancer (IARC) had formally declared that outside air air pollution is a Group 1 carcinogen in 2013.
A current research from the famend Francis Crick Institute within the United Kingdom, means that very small pollutant particles (PM2.5) within the air – from car exhaust fumes and combustion of fossil fuels, amongst others – could trigger irritation that predisposes to lung cancer.
Dr Anand notes that there’s rising proof that continual air air pollution triggers an inflammatory response at a mobile stage which will “activate” pre-existing dormant cancer genes or driver mutations (e.g. EGFR and KRAS) which will give rise to lung cancer within the inclined never-smoker.
This would account for the rising incidence of lung cancer detected in younger folks and non-smokers in densely populated, polluted city cities.
As a preventative measure, Dr Anand urges the general public to keep away from or stop smoking as it is a preventable danger issue for lung cancer.
However, we sadly have little management over the air we breathe, however he says that LCNM stays a vocal and powerful advocate for the Health Ministry’s proposed generational endgame tobacco ban as this may restrict the perils of secondhand smoke and defend future generations.

Most identified late
Compared to different forms of cancer like breast cancer and prostate cancer, most individuals with lung cancer are normally solely identified at a late stage.
According to Dr Tho, an awesome majority – over 90% of the lung cancer sufferers that he has encountered – offered in levels III and IV.
Stage IV lung cancer is taken into account incurable.
The motive for the late analysis is as a result of the symptoms of lung cancer will be troublesome to identify.
They are normally imprecise or non-specific, and will be simply disregarded as one thing far much less sinister.
“For example, it may be confused with a simple cold or chest infection,” Dr Tho says.
He provides that if the person is a smoker, the suspicion that it might be lung cancer could be even extra delayed as they could mistake the symptoms for his or her common smoke-induced symptoms, like coughing.
Lung cancer could cause coughing, ache within the chest, weight reduction, the manufacturing of blood whereas coughing, and shortness of breath, amongst others.
Do most of those symptoms sound acquainted to you?
They could even sound just like the frequent symptoms of Covid-19.
Dr Tho urges folks to not ignore these symptoms, particularly if they’ve skilled them for a chronic time period.
“It is imperative for you to seek medical attention and have the symptoms investigated as appropriate,” he says.
Early detection

The excellent news is that lung cancer will be detected early, even earlier than one has symptoms.
Dr Tho says: “There are available screenings that use a low-dose computed tomography (LDCT) scan.
“If detected early, lung cancer can be cured.”
According to Dr Anand, the LDCT scan is the gold normal for lung cancer screening.
Compared to the standard CT scan, which requires you to quick for a number of hours previous to the scan and entails use of a distinction dye, the LDCT scan is “quick, painless, does not involve needles and has minimal lower radiation”.
He provides that one shouldn’t be required to quick or do any blood assessments previous to the scan.
It is a single-breath expertise, which takes footage of the lung in a short time and supplies top quality detailed photographs.
The LDCT scan is advisable for women and men aged between 45 to 75 years outdated who’ve been smoking for 20 years or extra.
Meanwhile, for many who don’t have any historical past of smoking, there’s now a man-made intelligence (AI) screening programme that helps to detect early stage lung cancer.
“The sophisticated AI machine technology will automatically scan and quickly read the patient’s chest X-ray more accurately than the human eye can, as it is based on deep learning algorithms and will generate a detailed report,” says Dr Anand.
This is a possible gamechanger for lung cancer because it can’t solely help normal practitioners (GPs) in detecting lung cancer on the neighborhood stage, however will even improve diagnostic accuracy and expedite the referral of suspected circumstances to a related lung specialist, he provides.
Once the AI software program detects one thing uncommon on the X-ray, the affected person will be referred to a hospital that may conduct the extra detailed LDCT scan.
If the affected person is confirmed to have early stage lung cancer, they’ll obtain remedy to successfully remedy the cancer.
“With the LDCT scan and AI chest X-ray screening, we hope to achieve a true shift and detect more cases at an early stage when the disease can be treated more effectively – often less invasively and cheaply,” he says.
Not a demise sentence
Many folks assume or share a typical false impression that getting identified with lung cancer is akin to receiving a demise sentence, and as such, there is no such thing as a level in treating it.
According to Dr Tho, this was true prior to now when the anticipated survival price for stage IV lung cancer sufferers was roughly six months or much less.
However, due to large advances within the remedy of lung cancer similar to immunotherapy and oral focused therapies, this has modified.
He says: “With precision diagnostics and bespoke personalised therapies, we can now get even some stage IV patients surviving more than five years with a reasonably good quality of life.”
He and Dr Anand share the story of how one in all their youngest lung cancer sufferers has efficiently fought the illness.
The then 30-year-old girl had no historical past of smoking or cancer in her household, and didn’t expertise any lung cancer symptoms previous to the analysis.
Her cancer was an surprising discovering from a routine medical check-up.
Upon screening, she was identified with early stage IV lung cancer.
According to Dr Tho, the medical crew did a genetic check and located that her tumour had a mutation that might be focused by an obtainable drug.
They prescribed her this oral focused remedy.
Following a great response to the remedy, Dr Anand was capable of function on her and safely take away the tumour utterly.
Almost 5 years on, the docs share that the affected person stays nicely, cancer-free and is prospering.
However, Dr Anand notes that monetary toxicity is an actual concern as lung cancer remedy can value in extra of a six-digit determine, relying on the stage of the illness.
The remedy prices are usually much less if the illness is picked up earlier.
The finest outcomes are achieved with multimodal remedy, similar to surgical procedure together with immunotherapy or oral focused remedy, and a multi-disciplinary strategy with enter from completely different related specialist docs working intently collectively.
In conjunction with the New Normal, Same Cancer public service marketing campaign by LCNM, the National Cancer Society of Malaysia (NCSM) and Pink Unity, supported by AstraZeneca, vouchers for a reduced LDCT scan (together with physician’s session) to display for lung cancer will be downloaded here. They can be utilized at over 20 collaborating non-public hospitals throughout the nation.
