lung cancer
Lung cancer refers to malignant tumors originating in lung tissue and is one of the most common cancers worldwide in terms of both incidence and mortality. Its danger lies in the fact that early stages often present no obvious symptoms, causing many patients to be diagnosed at a middle or advanced stage, which increases the difficulty of treatment and supportive care. Lung cancer can be classified into two main types:
- Non-Small Cell Lung Cancer (NSCLC): Accounts for approximately 80–85% of lung cancers and includes adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. These tumors generally grow more slowly and metastasize at a lower rate, but early detection and personalized supportive care are still essential.
- Small Cell Lung Cancer (SCLC): Makes up about 15–20% of lung cancers. It grows rapidly and easily spreads to lymph nodes, liver, bones, and brain. Due to its fast progression, early diagnosis and proactive supportive care are particularly important.
The development of lung cancer is associated with multiple factors, with smoking being the primary cause. Other risk factors include long-term exposure to air pollution, asbestos, radiation, and certain chemicals, chronic lung diseases, or a family history of lung cancer.
Early symptoms of lung cancer are often subtle and easily overlooked, making regular check-ups and attention to bodily changes very important. As the disease progresses, patients may experience the following signs:
- Persistent or worsening cough: A previously occasional cough may gradually become more frequent and prolonged.
- Coughing up blood or blood-streaked sputum: Some patients may notice blood-tinged mucus or significant coughing of blood.
- Shortness of breath or chest pain: As the tumor grows or lung function is affected, patients may experience breathlessness, chest tightness, or chest pain.
- General symptoms: Unexplained weight loss, fatigue, loss of appetite, or low-grade fever.
- Other manifestations: In some advanced cases, patients may develop hoarseness, difficulty swallowing, bone pain, or neurological symptoms, indicating possible tumor metastasis.
Because these symptoms are similar to those of many respiratory conditions, early-stage lung cancer is often difficult to identify based on clinical symptoms alone, making medical examinations essential.
The diagnosis of lung cancer relies on multiple complementary examinations to ensure accuracy and provide a basis for subsequent care or treatment plans. The main methods include:
Imaging Examinations
Chest X-ray: Provides an initial assessment of lung structure abnormalities but has limited sensitivity for small early-stage lesions.
Chest CT (Computed Tomography): Offers a clearer view of tumor size, location, and involvement of surrounding tissues.
PET-CT (Positron Emission Tomography–Computed Tomography): Evaluates tumor metabolic activity and potential metastasis.
Bronchoscopy
Directly observes lesions inside the airways and allows tissue biopsy.
Suitable for detecting tumors located within or near major airways.
Histological Examination (Biopsy)
Tumor tissue obtained through needle biopsy or endoscopy is examined under a microscope to confirm tumor type.
Can determine whether the lung cancer is non-small cell or small cell, as well as grading and staging.
Molecular and Genetic Testing
Detects specific gene mutations or markers in the tumor, which helps guide personalized care or supportive strategies.
Assesses tumor sensitivity to certain medications or nutritional support regimens.
Lung cancer diagnosis is a systematic process. By combining symptom assessment, imaging, tissue biopsy, and molecular testing, healthcare professionals can design more precise care and support plans tailored to each patient.
Lung Cancer Treatments: Traditional Approaches and Personalized Support Strategies
The goal of lung cancer management is to slow disease progression, improve quality of life, and enhance the body’s resilience:
Surgery
-
Suitable for early-stage tumors; removes lesions and reduces the risk of recurrence.
-
Postoperative nutritional support and care can accelerate recovery.
Radiation and Chemotherapy
-
Used to control tumor growth or metastasis.
-
Can be combined with care plans to minimize side effects and maintain physical function.
Targeted and Immune-Related Support
-
Personalized care plans are developed based on molecular testing results.
-
Nutritional support and immune-enhancing interventions help strengthen the body’s resistance to disease.
Nutritional and Supportive Therapies
-
Includes intravenous therapies such as high-dose vitamin C, glutathione, amino acids, and trace elements.
-
Aims to improve patient energy levels, maintain immune function, and support overall health.
Personalized Monitoring and Care
-
Regular imaging, blood tests, and molecular assessments.
-
Develops individualized care plans, adjusting nutrition, lifestyle, and psychological support as needed.
-
For patients with long-term heavy metal exposure, chronic inflammation, or immune dysfunction, specialized supportive care programs can be provided.
