Introduction

Blood tests, including complete blood count, liver and kidney function, and tumor markers, are performed after blood collection to determine whether the surgery was curative and to monitor for possible recurrence. Lung cancer tends to metastasize to the liver, gallbladder, kidneys, pancreas, etc., so abdominal ultrasound is needed for further evaluation. Contrast-enhanced chest CT allows comprehensive assessment of regional lymph node metastasis or local tumor recurrence. After long-term stability, non-contrast chest CT can be used for follow-up examinations.

Generally, follow-up examinations after lung cancer surgery include blood tests, abdominal ultrasound, and enhanced chest CT scans. Specific details are as follows:

1. Blood Tests

After drawing blood, routine blood tests, liver and kidney function tests, and tumor marker tests are performed to determine whether the patient has been cured after surgery and to detect any signs of recurrence.

2. Abdominal Ultrasound

Lung cancer tends to metastasize to organs such as the liver, gallbladder, kidneys, and pancreas; therefore, an abdominal ultrasound is necessary to further confirm this possibility.

3. Enhanced Chest CT

This allows a comprehensive assessment of regional lymph node metastasis or local tumor recurrence. After long-term stability is achieved, non-contrast chest CT scans can be used for follow-up.

In addition, postoperative follow-up may also include lymph node ultrasound and bone scans. It is recommended to follow the doctor's instructions: have check-ups every three months during the first two years after surgery, and then every six months thereafter.

Why is chemotherapy required after major cancer surgeries?

In general, patients with cancers such as lung cancer, gastric cancer, and breast cancer often require chemotherapy after surgery due to surgical trauma and stress, decreased immune function, minimal residual disease, active cell proliferation, and increased potential for metastasis. 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.
