Introduction

The significance of the five-item lung cancer test lies in its ability to assist in the diagnosis of early-stage lung cancer, promptly detect recurrence, and monitor treatment response to guide medication use. The five-item lung cancer test is typically performed through blood sampling and mainly includes carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), squamous cell carcinoma-specific antigen (SCC), cytokeratin 19 fragment (CYFRA 21-1), and carbohydrate antigen 125 (CA125).

The significance of the five-item lung cancer screening lies in its ability to assist in the early diagnosis of lung cancer, timely detection of recurrence, and monitoring treatment response to guide medication use.

The five-item lung cancer test is generally performed via blood sampling and mainly includes carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), squamous cell carcinoma antigen (SCC), cytokeratin 19 fragment (CYFRA 21-1), and carbohydrate antigen 125 (CA125). This panel helps improve the detection rate of lung cancer, long-term prognosis, and overall 5-year survival rate. In cases where the five-item test results are elevated before treatment, tumor markers typically decrease following surgery or anti-tumor therapy. Postoperative retesting can serve as one of the key indicators for evaluating treatment effectiveness.

If lung cancer is confirmed, it is recommended to seek prompt treatment at a正规 medical institution, such as through lobectomy or wedge resection procedures. After treatment, regular follow-up examinations should be strictly conducted according to medical advice to continuously monitor recovery. In daily life, patients should abstain from alcohol and tobacco and correct unhealthy lifestyle habits.

If any discomfort occurs, seek timely medical evaluation and treatment at a正规 hospital. In daily life, it is important to maintain a balanced diet with adequate protein and vitamin intake, and to follow a regular sleep schedule, avoiding staying up late.

What does it mean when a late-stage lung cancer patient stops coughing?

In general, the absence of coughing in late-stage lung cancer may be due to reasons such as relieved dryness in the respiratory tract, stabilized emotional state, improvement of chronic bronchitis, atelectasis, or pleural effusion. If any discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. In daily life, ensure indoor air circulation; quit smoking and avoid secondhand smoke.

Which is more severe: novel coronavirus infection or lung cancer?

Novel coronavirus infection and lung cancer are two distinct diseases with different characteristics, and their severity must be evaluated on a case-by-case basis. In daily life, it is essential to quit smoking and avoid polluted environments to reduce irritation to the lungs. Ensure adequate nutritional intake, focusing on high-quality proteins, fresh vegetables, and fruits. Maintain regular作息 (daily routines), avoid overexertion, and engage in moderate exercise to strengthen physical health. Follow a scheduled routine for regular medical check-ups to enable early detection and early intervention of diseases.

Which internal organs can be damaged by smoking?

Smoking is extremely harmful to the human body and generally causes damage to the lungs, heart, liver, kidneys, and stomach. Harmful substances in tobacco smoke directly irritate the respiratory mucosa; long-term exposure can lead to chronic bronchitis, emphysema, and even lung cancer. Smoke also reduces pulmonary ventilation function, resulting in decreased respiratory efficiency and symptoms such as coughing and shortness of breath.

Can lung nodules cause back pain?

If a pulmonary nodule is relatively large in size (diameter exceeding 3 cm) or located close to the pleura, compressing or invading the pleura and surrounding nerve tissues, it may cause back pain. Some malignant nodules (such as early-stage lung cancer) can lead to radiating back pain when local invasion occurs. The pain is often described as dull or aching and may worsen with breathing or coughing, indicating a potential risk of disease progression that requires vigilance.
