Lung cancer remains one of the most common and deadly cancers affecting the population. According to data from the Centre for Health Protection, there were 5,707 new cases of lung cancer in 2022, accounting for 16.1% of all new cancer cases that year . The majority of patients were male, with 3,340 cases in men and 2,367 in women . These numbers reflect the prevalence of the conditions and the urgency in raising awareness about this disease.-What is Lung Cancer?Lung cancer is a malignant tumor that develops in the lower respiratory tract, specifically in the cells lining the walls of the bronchi and bronchioles. Lung cancer occurs when these cells begin to divide uncontrollably, forming abnormal growths or tumors. Typically, cells divide to repair and maintain tissue. When mutations happen, they cause excessive growth, resulting in masses that interfere with lung function and can spread to other parts of the body, leading to organ damage and breathing difficulties.-Lung cancer can be categorized into two main types:-●Non-small cell lung cancer (NSCLC):NSCLC is the most common form, making up 80–85% of all cases globally.●Small cell lung cancer (SCLC): SCLC is a less common type, accounting for approximately 15% of all lung cancers globally. This form of lung cancer is typically more aggressive and spreads more quickly than NSCLC.-While both types of lung cancer are serious, small cell lung cancer (SCLC) is considered more severe because it grows and spreads much faster than non-small cell lung cancer. SCLC often reaches an advanced stage by the time it is diagnosed, which makes it harder to treat effectively. As a result, treatment options are more limited, and the focus is often on slowing the cancer down and relieving symptoms rather than achieving a cure.-How Does One Get Lung Cancer?One of the most critical risk factors for lung cancer is cigarette smoking, which is linked to around 90% of all cases . A smoker’s risk of developing lung cancer can be up to 20 times higher than that of a non-smoker, with an average of 1 in 10 smokers who will eventually be diagnosed with the disease. The danger of lung cancer isn’t limited to smokers alone, as second-hand smoke exposure can increase the risk by two to three times , posing a serious threat to non-smokers, especially in densely populated areas like Hong Kong.-Poor dietary habits can also increase the risk of lung cancer. A long-term lack of fresh fruits and vegetables can mean the body is missing out on vital antioxidants and nutrients that help repair cell damage and prevent abnormal growth. Meanwhile, a frequent consumption of BBQ or preserved foods introduces carcinogens such as polycyclic aromatic hydrocarbons (PAHs) and nitrosamines, which are formed during high-heat cooking or food preservation.-The Symptoms of Lung CancerThe main challenge with lung cancer is that it shows no apparent symptoms in the early stages. The main symptoms usually appear only when the condition has progressed. The common lung cancer symptoms related to the lungs include:-Persistent coughA new cough that doesn’t go away may indicate irritation or blockage in the airways caused by a tumor.Chest painA discomfort or pain in the chest can be caused by tumors pressing on the lung tissue or chest wall.Coughing up bloodSmall amounts of blood in the mucus could be a sign that a tumor is damaging lung tissue-As the lung cancer spreads to other parts of the body, the symptoms can be different to the ones mentioned above:-Bone painWhen the cancer spreads to the bones, patients may feel deep or aching pain, especially in the spine and ribs.HeadachesMetastasis (cancer spreading beyond the place it first started) to the brain can cause persistent or severe headaches.Unexplained weight lossThe body is burning more energy as it fights the cancer, leading to weight loss even without dietary changes.-The Stages of Lung CancerLung cancer staging indicates the severity and location of the cancer within the body. Only applicable to NSCLC, The staging of lung cancer helps doctors determine the most appropriate treatment based on how advanced the disease is.-Lung Cancer StagingCharacteristics5-year Relative Survival RateStage 0Cancer is found only in the top layer of cells lining the airwaysYet to spread to the lymph nodes or other parts of the bodyN/AStage 1Cancer is limited to the lung and has not reached the nearby lymph nodes72.4%Stage 2Cancer has grown and may have spread to nearby lymph nodes45.4%Stage 3The cancer has spread to central chest lymph nodes or nearby structures like the esophagus or trachea24.6%Stage 4Cancer has metastasized to other organs such as the brain, liver, or bones7.8%-The Lung Cancer Treatment OptionsThe type of lung cancer treatment mainly depends on several factors, including the type, stage, and location of the cancer, as well as the patient’s overall health condition.-NSCLC Treatment OptionsFor non-small cell lung cancer (NSCLC), treatment often begins with surgery, particularly if the tumor is localized and detected early. In some cases, chemotherapy or immunotherapy may be given before surgery to shrink the tumor, or afterwards to eliminate any remaining cancer cells. Suppose surgery isn’t an option due to medical risks or the extent of the disease. In that case, Radiotherapy can be used as an alternative option to help control tumor growth and relieve symptoms.-SCLC Treatment OptionsAs small cell lung cancer is typically more aggressive and fast-growing, chemotherapy is the main form of treatment. Depending on how far the cancer has spread, radiotherapy or immunotherapy may also be used in conjunction to enhance the overall effectiveness. Surgery is rarely used for SCLC because it is usually diagnosed at a later stage when the cancer has already spread. In rare cases where the disease is detected very early, surgery may still be a viable option.-Facing Lung Cancer with Awareness and ActionLung cancer continues to pose a significant health challenge with its high prevalence in Hong Kong and its silent onset and aggressive progression. The disease is particularly concerning due to its deep connection to both lifestyle choices and environmental exposures. From cigarette smoking and second-hand smoke in densely populated areas to traditional practices like incense burning and frequent consumption of preserved foods, the risks are embedded in daily life more than many people realize.-While the disease can be severe, it is not untreatable. Early diagnosis through screening and awareness of symptoms plays a critical role in improving outcomes. At the same time, advances in surgical techniques and systemic therapies have made it possible to manage lung cancer as effectively as ever.-Reference:1.Centre for Health Protection. (2025).

Diabetes is one of the most common chronic conditions in the world today, and its presence is growing steadily in Hong Kong. Recent data from 2022 indicates that approximately 8.5% of Hong Kong residents aged 15 to 84 have diabetes or elevated blood glucose levels, with 5.4% self-reporting a doctor-diagnosed condition and an additional 3.1% identified through biochemical testing . With an increasingly busy lifestyle, long work hours, and dietary habits that lean towards convenience over nutrition, many working adults may unknowingly be placing their health at risk. Understanding diabetes is essential to managing the condition effectively and preventing complications from developing.-What is Diabetes?Diabetes is a condition where the body has difficulty regulating blood sugar (glucose) levels. There are two main types:-●Type 1 Diabetes:Usually diagnosed in children or young adults, Type 1 diabetes is caused by the immune system attacking insulin-producing cells in the pancreas. People with Type 1 diabetes have no insulin and need daily insulin injections to survive.-●Type 2 Diabetes: Far more common, especially among adults, Type 2 diabetes occurs when the body doesn’t use insulin properly or doesn’t produce enough. It's often linked to lifestyle factors such as diet, lack of exercise, and excess weight.In both cases, unmanaged diabetes leads to high blood sugar levels, which over time can damage vital organs like the heart, kidneys, eyes, and nerves.-Risk Factors for DiabetesSeveral factors can contribute to an increased risk of developing Type 2 diabetes. These include:-Sedentary lifestyleLack of regular physical activity can contribute to insulin resistance.Unhealthy dietHigh intake of refined carbohydrates, sugary foods, and processed snacks can lead to weight gain and higher blood sugar levels.Family historyHaving a parent or sibling with diabetes raises your risk.Being overweight or obeseExcess body fat, especially around the abdomen, is a major risk factor.AgeThe risk of Type 2 diabetes increases after the age of 45.High blood pressure or abnormal cholesterol levelsThese conditions often occur alongside diabetes and may signal underlying metabolic issues.-Understanding and managing these risk factors can go a long way in preventing or delaying the onset of diabetes.-Common Symptoms and Early Warning SignsWhile Type 2 diabetes often develops gradually, making early symptoms easy to overlook, both Type 1 and Type 2 diabetes share common warning signs. These symptoms can include:-●Frequent urination●Excessive thirst or hunger●Fatigue●Blurred vision●Slow wound healing●Numbness or tingling in the hands or feet-Prompt consultation with a healthcare provider is important if any of these symptoms are noticed, as early diagnosis significantly reduces the risk of complications.-How is Diabetes Diagnosed?Diagnosing diabetes typically involves a series of blood tests that measure how effectively the body manages glucose. These tests are usually recommended if diabetes symptoms are present or if an individual falls into a high-risk group.-The most commonly used diagnostic tests include:-Fasting Blood Sugar TestThe Fasting Blood Sugar Test measures blood glucose levels after fasting (having nothing to eat or drink except water) for at least 8 hours. Blood glucose levels are measured in millimole per litre (mmol/L), a unit that indicates the concentration of glucose in blood. In the USA, it is usually expressed in milligrams per deciliter (mg/dL). -Interpreting the test results:●Normal: A result below 5.6 mmol/L (100 mg/dL) is considered within the healthy range.●Prediabetes: A reading between 5.6 to 6.9 mmol/L (100 and 125 mg/dL) indicates prediabetes, a condition where your blood sugar levels are higher than normal but not high enough to be classified as diabetes.●Diabetes: A result of 7.0 mmol/L (126 mg/dL) or higher on two separate occasions confirms a diagnosis of diabetes.-What Does Prediabetes Mean for Your Body?When blood sugar levels fall within the prediabetes range (5.6 to 6.9 mmol/L), it indicates that the body is beginning to have difficulty managing glucose. During this stage, the body’s cells become less responsive to insulin, the hormone responsible for regulating blood sugar levels. Although diabetes has not yet developed, prediabetes significantly increases the risk of progressing to Type 2 diabetes over time. However, with lifestyle changes, such as adopting a healthier diet, increasing physical activity, and losing weight, it’s possible to return blood sugar levels to normal and prevent the onset of diabetes.-HbA1c Test (Glycated Haemoglobin)The HbA1c test measures the average blood sugar levels over the past 3 months by determining the percentage of haemoglobin bound to sugar in the blood.-○A level below 5.7% is considered normal.○A level between 5.7% and 6.4% indicates prediabetes.○A level of 6.5% or higher typically confirms diabetes.-Oral Glucose Tolerance Test (OGTT)Often used for diagnosing gestational diabetes (during pregnancy), this test involves taking a fasting blood sugar reading, drinking a glucose-rich beverage, and then measuring blood sugar levels at intervals (usually after 1 and 2 hours).○A 2-hour glucose level of 11.1 mmol/L (200 mg/dL) or higher suggests diabetes.-Random Blood Sugar TestThe Random Blood Sugar Test measures blood sugar at any given time, regardless of when the individual last ate. A result of 11.1 mmol/L (200 mg/dL) or higher, coupled with symptoms of diabetes, may be sufficient to confirm a diagnosis.-Managing Diabetes: Lifestyle and Medical ApproachesWhile diabetes is a lifelong condition, both type 1 and type 2 can be effectively managed through a combination of healthy habits and medication if needed.-1. Balanced DietA healthy diet plays a crucial role in managing diabetes. It helps regulate blood sugar, maintain a healthy weight, and reduce the risk of complications. Here’s how to make smarter food choices:-●Whole Grains & Vegetables: Opt for whole grains like brown rice and whole wheat, and fill half your plate with non-starchy vegetables. These foods are high in fiber, which helps control blood sugar levels.●Lean Proteins: Include sources like fish, poultry, beans, and tofu. Lean proteins help stabilize blood sugar without adding unhealthy fats.●Limit Sugary Foods & Processed Grains: Reduce sugary snacks, drinks, and processed foods, as they can cause blood sugar spikes. Replace refined grains like white rice with whole grains for better blood sugar control.●Portion Control: Use smaller plates and measure food to avoid overeating. Portion control helps manage calorie intake and blood sugar levels.●Plan Ahead: Preparing meals in advance ensures healthier choices and prevents last-minute unhealthy options. Cooking at home gives you control over ingredients and portion sizes.●Consult a Dietitian: A registered dietitian can provide personalized meal plans and help you manage carb intake and food choices for better diabetes control.-2. Regular Physical ActivityExercise enhances the body's ability to use insulin more effectively. It is recommended to engage in at least 150 minutes of moderate physical activity per week, such as brisk walking, swimming, or cycling. Even small changes, like taking the stairs or walking during lunch breaks, can have a positive impact on blood sugar levels.-3. Medication and InsulinSome individuals with diabetes may require oral medications or insulin therapy to maintain healthy blood sugar levels. A healthcare provider will determine the most appropriate treatment plan. It is important to follow the prescribed regimen and attend regular medical check-ups.-4. Monitoring Blood SugarUsing a home glucose monitor can help individuals understand how different lifestyle choices impact their blood sugar. This enables adjustments to diet, physical activity, or medications to maintain optimal blood sugar control.-5. Regular Check-upAt Blue Care, we offer a diverse range of health screening packagestailored to meet the needs of individuals at different stages of life.

In recent years, Hong Kong's weather has become increasingly hot, with 2024 marking a record-breaking year for high temperatures in the city. According to reports, Hong Kong broke 35 temperature records, reaching highs of 35.7 °C in 2024, making it the hottest year in the city's history . This trend is concerning, especially given the potential risks of heat-related illnesses.-Outdoor workers are particularly vulnerable to these conditions. A survey revealed that 60% of Hong Kong’s outdoor workers experience symptoms of heat stroke. Heat stroke and heat exhaustion are two serious health concerns that can arise from prolonged exposure to extreme heat. Therefore, understanding these conditions can help reduce the risk of heat-related illnesses.-What is Heat Exhaustion?Heat exhaustion is a condition that results from prolonged exposure to high temperatures, typically accompanied by dehydration. It is often seen in situations where a person is exposed to excessive heat for an extended period or engages in strenuous physical activities in hot weather. -What Are the Symptoms of Heat Exhaustion?The body loses a significant amount of water and salt, which can lead to the onset of symptoms such as:·Heavy sweating·Dizziness or light-headedness·Nausea or vomiting·Headache·Fainting or weakness-Several factors can increase the risk of heat exhaustion, including:·High humidity: Elevated humidity levels can prevent sweat from evaporating efficiently, making it harder for the body to cool down.·Strenuous physical activity: Engaging in physical exertion during hot weather, particularly for prolonged periods, places additional strain on the body’s ability to regulate temperature.·Wearing heavy clothing: Clothing that traps heat and prevents the evaporation of sweat can exacerbate the symptoms of heat exhaustion.-If left untreated, heat exhaustion can escalate into more severe heat-related conditions, including heat stroke.-What is Heat Stroke?Heat stroke is a much more severe condition than heat exhaustion. It occurs when the body’s core temperature rises to dangerously high levels, typically above 40°C (104°F) . This condition is a medical emergency and requires immediate intervention. -What Are the Symptoms of Heat Stroke?·Symptoms of heat stroke include:·Confusion or altered mental state· Slurred speech· Rapid or weak pulse· Hot, dry skin (lack of sweating)· Loss of consciousness or fainting-Heat stroke is a life-threatening condition, and if not treated immediately, it can cause organ damage or even be fatal. It typically occurs when heat exhaustion is left untreated, and the body’s cooling mechanisms fail to keep up with the rising temperature.-How to Prevent Heat Stroke & Heat ExhaustionPreventing heat stroke and heat exhaustion is critical, especially during periods of extreme heat. Below are several preventive measures that can help reduce the risks:-Stay hydratedIt is essential to drink plenty of fluids, especially water, to avoid dehydration. Water helps regulate body temperature and replace fluids lost through sweating. Electrolyte-rich drinks can also help maintain the balance of salts and minerals in the body.Wear appropriate clothingLoose-fitting, light-colored clothing allows for better air circulation and helps keep the body cool. Additionally, wearing hats or using sunscreen can protect the skin from the harmful effects of the sun.Limit physical activityAvoid strenuous outdoor activities during the hottest parts of the day, typically between 10 a.m. and 4 p.m. If physical activity is necessary, take frequent breaks and rest in the shade or a cool area.Use fans and air conditioningWhenever possible, stay indoors in air-conditioned spaces or use fans to help cool the environment. This is especially important for vulnerable groups, such as children, the elderly, or individuals with pre-existing health conditions.Monitor vulnerable groupsEnsure that young children, the elderly, and individuals with chronic health conditions are closely monitored during extreme heat. They are more susceptible to heat-related illnesses and may not be able to regulate their body temperature effectively.-What to Do in Case of Heat ExhaustionIf someone shows symptoms of heat exhaustion, it is important to act quickly:Assist the person to a cooler environmentRelocate them to a shaded or air-conditioned area to help lower their body temperature.Provide cool waterOffer small sips of cool water to help rehydrate the individual. Avoid offering drinks that contain caffeine or alcohol, as they can dehydrate the body further.Encourage restAllow the personto rest and recover in a cool environment. Avoid any further physical exertion until they have fully recovered.-If the symptoms worsen or do not improve with these steps, seek medical attention immediately, as heat exhaustion can escalate into heat stroke.-What to Do in Case of Heat StrokeHeat stroke is a medical emergency. If heat stroke is suspected, follow these steps:Call emergency services immediatelyHeat stroke requires urgent medical attention. Call 999 or your local emergency number to get immediate help.Cool the person downWhile waiting for medical help, attempt to cool the person down by moving them to a shaded or air-conditioned area. Use cool water, ice packs, or fans to reduce their body temperature. Ice packs should be placed on areas like the armpits, groin, neck, and wrists, as these areas contain large blood vessels that can help cool the body more effectively.Do not attempt to give fluidsUnlike heat exhaustion, individuals with heat stroke may be unconscious or unable to swallow, so avoid giving them any fluids.-Prompt action is critical to prevent long-term damage or death from heat stroke.-What is the Difference Between Heat Exhaustion and Heat StrokeUnderstanding the key differences between heat stroke and heat exhaustion is crucial for proper identification and effective management of these conditions. The main distinctions lie in core temperature, symptoms, severity, and treatment.-ConditionHeat ExhaustionHeat StrokeCore TemperatureLess than 40°C (104°F) Above 40°C (104°F)SymptomsHeavy sweating, dizziness, nausea, fatigueConfusion, slurred speech, hot skin (lack of sweating),unconsciousnessSeverityLess severe, but can progress to heat strokeLife-threatening, requires immediate medical attentionTreatmentRest, oral hydration, and a cool environmentImmediate medical attention with intravenous fluid, and cooling the body down with ice packs-It is important to note that while heat exhaustion can often be managed with rest and hydration, heat stroke is an emergency situation requiring immediate intervention.-Staying Safe in Extreme Heat: Key TakeawaysRecognizing the symptoms of heat stroke and heat exhaustion, and understanding the differences between these two conditions, is essential to staying safe in extreme heat. Proactive measures, such as staying hydrated, wearing appropriate clothing, and limiting physical activity during the hottest parts of the day, can significantly reduce the risks. In cases where these conditions do occur, swift action is required to prevent further harm. -By being aware of the symptoms and treatment strategies for heat-related illnesses, you can protect yourself and your loved ones from the dangers of heat stroke and heat exhaustion.-Blue Care Consultation ServicesBlue Care Medical Centres staffed with highly qualified family doctors provide family doctor consultation.-For appointment, please contact Blue Care Medical Centre.-Central clinic Tel : 2523 1808Address : 10/F, 33 Des Voeux Road Central, Central, Hong Kong(MTR Central Station Exit “B” or Hong Kong Station Exit “C”)-Kwun Tong clinic Tel : 2523 9383Address: Unit 2802, 28/F, BEA Tower, Millennium City 5, 418 Kwun Tong Road, Kowloon (MTR Kwun Tong Station Exit “A2”)-Reference:1.
