Pneumonia: Not Just an Older Person’s Disease

“Pneumonia is often misunderstood as an elderly disease, but anyone can get it — even healthy, young adults.” – Dr Aneez D.B. Ahmed

Pneumonia is an infection of the lungs that causes the air sacs to fill with fluid or pus. It can range from mild to life-threatening, depending on the severity of the infection, the type of pneumonia, and a person’s overall health.

Early Cases Highlight the Danger of Pneumonia (0:03–0:17)

Pneumonia can affect people of all ages. Some high-profile cases include:

February 2015: Singapore’s founding Prime Minister, Mr Lee Kuan Yew, was admitted with pneumonia and passed away the following month.
April 2025: Actor Val Kilmer died from pneumonia.

“These cases show that pneumonia is serious and should never be underestimated,” notes Dr Aneez.

What Is Pneumonia? (0:49–1:30)

Pneumonia occurs when the lungs’ air sacs become inflamed and filled with fluid. If bacteria, viruses, or other pathogens infect this fluid, it becomes pus, making the condition severe.

Inflammation alone is not pneumonia; infection must be present.
Left untreated, pneumonia can be life-threatening.

Who Can Get Pneumonia? (2:36–3:22)

Pneumonia can happen to anyone, but risks are higher at the extremes of age or when underlying conditions exist.

High-risk groups: very young, seniors, people with chronic conditions, immunocompromised individuals, smokers, vapers, and long-term care residents.
Middle-aged adults without health issues can also develop pneumonia, especially if exposed to infections while travelling or under stress.

Symptoms: How Pneumonia Differs from Flu (3:22–4:43)

Pneumonia can present like the flu:

Symptom	Bacterial Pneumonia	Viral Pneumonia
Cough	Phlegm, often yellow	Dry
Fever	High	High
Body aches	Mild	Headaches/body aches
Shortness of breath	Common	Less common

“All pneumonias must be treated with equal seriousness — don’t assume viral is mild.” – Dr Aneez

Diagnosis (5:23–6:38)

Doctors may use:

Blood tests for infection markers
Cultures to identify bacteria
Chest X-rays or low-dose CT scans to view lungs
Bronchoscopy in severe cases to remove fluid and test for infection
Home monitoring with a pulse oximeter can help detect early oxygen drops

Types of Pneumonia (6:41–7:08)

Bacterial pneumonia – often treatable with antibiotics
Viral pneumonia – may be self-limiting but requires monitoring
Other types – tuberculosis-related pneumonia

“Viral pneumonia can still be serious and may require active intervention.” – Dr Aneez

Real-Life Experience: Jarrett’s Story (8:08–11:51)

Jarrett, 42, a fit and active adult, contracted bacterial pneumonia during a holiday.

Symptoms: fever, severe cough, tight chest
Oxygen dropped below 80% → emergency hospitalisation and ICU stay
Recovery involved home oxygen and medications for a month, with careful monitoring and lifestyle adjustments
Even fit individuals must take pneumonia seriously

“You always need to be proactive about health — tracking oxygen, blood tests, and exercise helps reduce risk.” – Jarrett

Recurrence and Recovery (12:00–15:06)

Pneumonia can recur, especially in immunocompromised individuals or those with prior lung damage.
Recovery duration depends on severity and fitness:
- Fit adults: 3–6 weeks
- Less fit adults: weeks to months, sometimes up to 6 months
Recurrent infections can cause deconditioning, requiring rehabilitation for diet, exercise, and lung function

Smoking, Vaping, and Pneumonia Risk (16:02–19:12)

Vaping reduces lung immunity and increases susceptibility to pneumonia.
Teens and young adults are particularly at risk due to easy access and underestimation of harm.
Smoking and vaping create long-term risks that may only show up years later.

“Vaping compromises your lungs’ defenses, inviting infection.” – Dr Aneez

Prevention Tips (20:04–20:47)

Don’t smoke or vape
Exercise regularly (aerobic + resistance training for those 50+)
Maintain a healthy diet
Take flu vaccines and pneumococcal vaccines as recommended
Travel safely with hygiene measures (hand washing, masks, monitoring oxygen)

Key Takeaways

Pneumonia can affect anyone, not just seniors.
Early symptoms can mimic flu, but untreated pneumonia can be severe.
Both bacterial and viral types require careful management.
Fitness and proactive health monitoring improve recovery and reduce risk.
Preventive measures like vaccination, avoiding smoking/vaping, and maintaining immunity are crucial.

Robotic Thoracic Surgery in Singapore: A New Era of Care for Patients

Introduction

At the heart of Singapore’s healthcare is the constant pursuit to offer patients safer, more precise, and less invasive treatments. Robotic-assisted thoracic surgery (RATS) is one such advancement, enhancing the way chest surgeries are performed. For many patients facing lung or chest diseases, robotic surgery brings the promise of a quicker recovery, less pain and optimal outcomes.

Understanding Robotic-Assisted Thoracic Surgery

If you or your loved one is recommended for robotic thoracic surgery, it is natural to have questions. Simply put, robotic-assisted thoracic surgery is a way for doctors to perform delicate operations inside the chest using robotic technology.

However, it is important to know that the robot never operates by itself. A highly skilled surgeon sits at a console just a few feet away, controlling robotic arms that move with precision — even more finely than human hands could. Through small openings, the surgeon can perform complex surgeries with the help of a high-definition, 3D camera that gives a detailed view of the inside of the chest. This combination of human expertise and technology allows for surgery that is more accurate, less invasive, and ultimately more beneficial to patients.

Role of Robotic Surgery in Lung Cancer Treatment

Lung cancer is one of the most common and serious health challenges in Singapore. When detected early, surgery can offer the best chance for cure. Robotic surgery has become a powerful tool in treating early-stage lung cancer. Surgeons can remove cancerous parts of the lung and check nearby lymph nodes without having to make large cuts. The benefits of robotic surgery for lung cancer entail:

Less pain after surgery
Lower chances of complications
Faster return to normal life

Local mid-term results, including those published by Dr Aneez Ahmed in the Journal of Thoracic Diseases, have confirmed that completely portal robotic lobectomy for Stage I and II non-small cell lung cancer achieves excellent oncological outcomes with rapid post-surgical recovery.

Robotic Lung Surgeon Dr Aneez believes that with earlier cancer detection from lung screening programmes in Singapore, robotic surgery will be key to improving survival rates and quality of life.

Role of Robotic Thoracic Surgery in Treatment of Mediastinal Tumours

The mediastinum is the space between your lungs where important organs like the heart and major blood vessels sit. Tumours in this area can be tricky to reach. In the past, surgeons often had to make large chest openings to remove them.

Today, robotic thoracic surgery changes that. Using small keyhole-sized incisions, surgeons can remove mediastinal tumours, including thymomas, cysts, and benign growths, with great care and less trauma. In Singapore, many patients have benefited from robotic surgery for these conditions, experiencing shorter hospital stays, quicker recoveries, and enhanced outcomes without the burden of large surgical scars.

Advantages of Robotic Surgery to Patients in General

Robotic thoracic surgery offers many patient-centred benefits:

Smaller incisions mean minimal scarring
Less blood loss during surgery
Reduced pain, often requiring fewer painkillers
Shorter hospital stay, sometimes just 2–3 days
Faster return to daily activities and work
Lower risk of wound infections

Another remarkable advantage is the surgical precision that helps protect vital structures like nerves, resulting in fewer long-term side effects, such as chronic pain or voice changes.

As a surgeon, Dr Aneez has experienced firsthand how patients recover not only faster but also more confidently after robotic procedures, regaining their normal life activities with less disruption.

Challenges in Robotic Surgery Implementation

While robotic surgery brings great promise, it also faces challenges:

The cost of robotic systems and maintenance is high.
Surgeons and their teams require specialised training and ongoing practice.
Not every hospital can immediately offer robotic surgery because it requires significant investment in technology and infrastructure.
Some patients are understandably anxious about the idea of a robot being involved in their surgery.

I believe that educating patients and families about the human-driven nature of robotic surgery — and maintaining the highest standards of surgical training — are essential steps for making this technology more widely available and trusted across Singapore.

Future of Robotic and AI in Thoracic Surgery in Singapore

Looking ahead, the combination of robotic surgery and artificial intelligence (AI) will further enhance the way chest surgeries are performed.

Dr Aneez comments, “Imagine robotic systems that can assist surgeons in real-time by highlighting important blood vessels or warning about dangerous areas. AI could help doctors plan surgeries better, predict risks more accurately, and even offer support for remote surgery — where an experienced surgeon in one hospital could assist a surgery happening elsewhere in Singapore or abroad.

With Singapore’s strong focus on medical innovation, I am confident we will be among the leaders in advancing these technologies for patient benefit.”

Conclusion

Robotic thoracic surgery is not just about using new machines — it is about giving patients better care.

Through smaller incisions, faster recovery, and safer outcomes, robotic surgery is changing lives in Singapore. As technology and surgical expertise continue to evolve hand-in-hand, patients can look forward to a future where even complex chest conditions are treated with minimal discomfort and maximum success.

For those facing thoracic surgery, knowing that Singapore offers world-class robotic options should be a source of reassurance and hope.

10 Medical Myths About Lung Cancer Answered By a Lung Specialist

Introduction

Lung cancer happens due to excessive and uncontrolled cell division of cells in the lung, resulting in the growth of tumours. There are 2 major types of lung cancer—non-small cell lung cancer (NSLC) and small cell lung cancer (SCLC).

In Singapore, lung cancer is the second most common type of cancer among men and the third most common among women. It is also the most common cause of cancer death worldwide.

Here are 10 medical myths about lung cancer, answered by a lung specialist:

Myth #1: “Only smokers can get lung cancer”

While lung cancer has always been thought to have been mainly associated with people who smoke, there is now a significantly higher proportion of non-smokers among those diagnosed with lung cancer in Singapore.

A 2018 study by the National Cancer Centre Singapore (NCCS) showed that 48% of people diagnosed with non-small cell lung cancer were actually non-smokers, and the trend has been rising, especially in non-smoking women.

Myth #2: “I’ve smoked for years, there’s no point stopping now”

Smoking cessation is always a good thing, no matter how many years you have smoked. Damage and risks associated with tobacco smoking usually have a cumulative effect, and sequelae of smoking may only manifest many years later.

Quitting smoking as soon as possible will help to minimise your health risks in the future, and may also halt the progression of any lung and organ damage that has already occurred. In fact, after smoking, your lungs start to heal and regenerate. For example, the cilia (tiny hair-like structures that line the lungs) start to regain normal function in weeks to months.

Myth #3: “If you have lung cancer, it doesn’t pay to quit smoking”

No matter which stage you are at in your health journey, quitting smoking is beneficial for your health. In fact, when you have lung cancer, your treatment plan will require surgery or chemotherapy and/or radiotherapy. This will require you to maintain your health well to minimise side effects of these treatments and ensure they are the most effective they can be. Continuing to smoke increases the chance of recurrence in a previously treated cancer.

If lung cancer is detected early, there is as high as an 80% chance of cure (Stage I). Early diagnosis may also make you eligible for a minimally invasive thoracic procedure, which entails faster recovery and a shorter hospital stay.

Myth #4: “Lung cancer surgery causes cancer to spread”

A properly done operation will not spread lung cancer. A thorough lung surgeon, along with advancements in equipment and detailed imaging tests, makes this risk very low.

Lung cancer surgery is usually done to remove the tumour from the lungs, and to ensure that all of it is removed, a small sliver of normal lung tissue is usually removed together with the tumour to make sure nothing is left behind.

Myth #5: “I don’t have symptoms, so I don’t have lung cancer”

Lung cancer may be very insidious, and signs and symptoms typically only present in the late stages of the disease. In fact, only around 20%-25% of lung cancers are detected early.

Early lung screening involves a low-dose CT scan, which allows your doctor to detect asymptomatic lung cancer.

Myth #6: “Lung cancer is definitely terminal”

Not all lung cancers are diagnosed during end-stage disease. In some cases, patients maybe cured completely after surgical removal of the tumour. This is especially so if the cancer is detected in its early stages.

Myth #7:“Smoking is the only risk factor for lung cancer”

Other environmental risk factors aside from tobacco smoking include second-hand smoke exposure and air pollution. Chemical exposure to substances such as asbestos and occupational hazards for those working in chemical industries.

Myth #8: “A polluted environment poses a greater risk for lung cancer than smoking”

Although both smoking and air pollution is linked to lung cancer, smoking remains the biggest risk factor for lung cancer.

Myth #9: “I am too old to receive lung cancer treatment”

Nobody is too old to receive treatment. In fact, elderly patients are candidates for cancer treatment for all types of cancers. Whether or not you are eligible typically depends on your medical background and overall health condition.

Myth #10: “Switching to e-cigarettes (vaping) reduces my risk of lung cancer”

E-cigarettes typically contain substances such as nicotine and other toxic chemicals, which can still damage the lung and increase the risk of lung cancer. It is also important to note the long-term effects of vaping are still being studied, and it is advised to err on the side of caution. A better alternative would be to stop smoking completely, and not use e-cigarettes as a replacement, as they are still harmful to health.

Summary

Overall, lung cancer is very common, and understandably, there are many misconceptions surrounding the topic. However, because of its prevalence, it is important to be well-informed.

In Singapore, lung cancer screening is not part of the general population-level cancer screening regimen yet. However, lung cancer screening may be recommended by some doctors for those with risk factors such as having a ≥20 pack-year (1 pack year refers to smoking an average of 1 pack of cigarettes per day, for a year) smoking history, in the elderly, or those who have been regular smokers anytime within the last 15 years, people with a family history of lung cancer, and people with a history of other cancers. Lung cancer screening may be done using a low-dose computed tomography (LDCT) scan, which can help to take detailed images of the lungs to help look out for any tumours.
