Lung cancer is one of the most common and deadly malignancies worldwide, and a major type of tumor within the respiratory system. With industrialization, population aging, and environmental changes, lung cancer prevention and control have become critical public health priorities.

I. Understanding Lung Cancer: A Common Yet Preventable and Manageable Disease

🫁 Lung cancer originates from epithelial cells in the bronchi or alveoli. It ranks among the leading causes of cancer incidence and mortality globally. Because early symptoms are often subtle, many patients are diagnosed at advanced stages, making public awareness especially important.

Based on pathology, lung cancer is mainly divided into two types:

● Non-Small Cell Lung Cancer (NSCLC): ~85%, including adenocarcinoma and squamous cell carcinoma

● Small Cell Lung Cancer (SCLC): ~15%, highly aggressive and fast-growing

Among these, adenocarcinoma is currently the most common subtype, especially among non-smokers.

II. High-Risk Factors: Are You at Risk?

Lung cancer does not occur by chance—it results from long-term exposure to multiple risk factors:

1. Smoking and Secondhand Smoke

Smoking is the leading cause. Long-term smokers have a significantly higher risk, and passive smoking is also harmful.

2. Air Pollution and Environmental Exposure

Includes PM2.5, industrial emissions, and cooking fumes. Long-term exposure can damage the lungs.

3. Occupational Carcinogens

Substances such as asbestos, arsenic, nickel, and chromium are strongly linked to lung cancer.

4. Genetics and Chronic Lung Diseases

Family history, COPD, and pulmonary fibrosis may increase risk.

⚠️ Notably, lung cancer among non-smokers has been rising, highlighting the role of environmental and genetic factors.

III. Symptoms & Screening: Early Detection Is Key

Common Symptoms

Early-stage lung cancer is often “silent,” but as it progresses, symptoms may include:

●  Persistent or worsening cough

●  Coughing up blood

●  Chest pain or shortness of breath

●  Hoarseness

●  Unexplained weight loss

If these symptoms persist, medical evaluation is essential.

Scientific Screening

1. Low-Dose CT (LDCT)

Recommended for high-risk individuals (e.g., long-term smokers). It helps detect lung cancer early and improves survival rates.

2. Imaging Tests

Chest CT and PET-CT assess tumor size, location, and metastasis.

3. Pathological Diagnosis

Tissue samples obtained via bronchoscopy, biopsy, or surgery remain the gold standard.

4. Molecular Testing

Gene testing (e.g., EGFR, ALK) is crucial for NSCLC patients to guide targeted therapy.

With the rise of precision medicine, genetic testing is becoming an essential part of diagnosis and treatment planning.

IV. Lung Cancer Treatment: From Traditional to Precision Medicine

Treatment has evolved into a multidisciplinary approach, including:

1. Surgery

Best option for early-stage patients with curative potential.

2. Radiotherapy and Chemotherapy

Traditional but still important, especially for advanced stages.

3. Targeted Therapy

Targets specific mutations (e.g., EGFR, ALK), offering higher efficacy and fewer side effects.

4. Immunotherapy

Activates the immune system to fight cancer and has become a major breakthrough in recent years.

In this evolving landscape, companies like Dengyue Pharma are helping improve access to innovative global therapies, enabling patients to benefit from advanced treatment options.

V. Prevention & Future Trends: Proactive Health Management Matters

Preventing lung cancer focuses on reducing risk factors:

● Quit smoking – the most effective measure

● Avoid secondhand smoke

● Reduce air pollution exposure

● Maintain a healthy diet

● Regular health check-ups, especially for high-risk groups

● Occupational protection

Looking ahead, lung cancer management is moving toward:

●  Early screening and diagnosis

●  Precision and personalized treatment

●  Liquid biopsy and AI-assisted diagnostics

●  Development of novel anti-cancer therapies

Conclusion

Although lung cancer is a serious disease, it is preventable and manageable with proper awareness and timely intervention.

For individuals: avoid smoking, pay attention to symptoms, and undergo regular screening.

For society: strengthen education and optimize healthcare resources.With continuous medical advancements and growing health awareness, lung cancer is no longer an untreatable disease—but one that can increasingly be managed and even overcome.
