What are the common internal and external symptoms of lung cancer? Six common internal and external symptoms of lung cancer

If you know the symptoms of lung cancer and go to the hospital for treatment in time after discovering these symptoms, I believe you can regain your health. Therefore, it is very necessary to understand the common internal and external symptoms of lung cancer. The following experts will give you a detailed introduction on this issue.

1. About 1/3 of early lung cancer cases have no symptoms, but are often found during physical examinations. The early symptoms of early intermediate lung cancer are mostly cough. Its characteristics are: irritating cough, no sputum or a small amount of white foamy sputum. This kind of cough is ineffective with general cough suppressants.

2. Some patients who had chronic bronchitis and chronic cough in the past, after the onset of intermediate lung cancer, the nature of their cough, the regularity of time, and the response to drug treatment are different from the previous "old cough". In this case, fiberoptic bronchoscopy is required to assist in a clear diagnosis.

3. Irritating cough with segmental pneumonia, especially the anterior segment of the upper lobe, the lingual segment or the dorsal segment of the lower lobe, is often a signal of early intermediate lung cancer. Hemoptysis or blood in sputum: Generally, the amount of hemoptysis is very small or there is only a few blood in the sputum.

4. Repeated pneumonia occurs on the same side of the lung, in the same part, and the size of the pneumonia increases over time. The vast majority of patients with early peripheral lung cancer have no symptoms.

5. The first symptom of early peripheral lung cancer is often mild chest pain, which is generally mild and can occur in the chest cavity on the same side as the lung cancer or on the opposite side.

Peripheral lung cancer is easily found on chest X-rays, manifesting as spherical lesions in the lung field, accompanied by small lobes or short spurs. Generally, chest X-rays can detect lesions with a diameter of 1.0 cm, and chest CT scans can detect lesions with a diameter of 0.5 cm. The manifestations outside the lungs, which often appear before the lung manifestations, become early signs of lung cancer. Paying attention to identifying these signals is helpful for the diagnosis of early lung cancer.

1. Clubbing, also known as drumstick finger, is characterized by hypertrophy of the first section of the fingers and toes, protrusion and bending of the nails, and is often accompanied by pain. It is reported that 21% of early lung cancer is accompanied by clubbing, which mostly disappears after lung surgery.

2. Low-grade fever. When the tumor blocks the bronchus, there is often obstruction of the lung lobe, which can be relieved later, but will recur soon. The degree varies, with mild cases having low-grade fever and severe cases having high fever.

3. Bone and joint manifestations are more common. Lung cancer cells can produce certain special endocrine hormones (xenohormones), antigens and enzymes, which act on the bone and joint parts, causing bone and joint swelling and pain, often involving the tibia, radius, ulna, fibula and other bones and joints, often with clubbing, and can first appear when the lung cancer lesions are very small and difficult to be found.

4. Hoarseness. Lung cancer metastasis compresses the laryngeal nerves. Metastasis can appear in the early stage, and metastasis sometimes grows faster than the primary lesion. Therefore, the clinical manifestation of metastasis can appear before the primary lesion. It can cause vocal cord dysfunction and cause hoarseness.

5. Shoulder and back pain Peripheral lung cancer often spreads backward and upward, corroding the pleura, involving the ribs and chest wall tissue, and then causing shoulder and back pain. Such patients rarely have respiratory symptoms. Acanthosis nigricans: mainly thickening and pigmentation of the skin on the flexor surface of the armpits and limbs.

6. Neurological manifestations: Lung cancer brain metastasis can cause headaches, sudden fainting, aphasia, hemiplegia, vomiting and other neurological manifestations. Because the lung manifestations are not obvious, they are often misdiagnosed as cerebral embolism, brain tumors and other diseases.

What you have seen above are the common internal and external symptoms of lung cancer. When you find yourself experiencing one or several of the above symptoms, you must not be careless and should go to a professional and regular hospital for further examination and treatment in time. Finally, I would like to remind everyone not to panic too much when the above symptoms appear, but to face them bravely.
