1. Cough: Cough is one of the important symptoms in the early stage of lung cancer. Because the pathological changes of lung cancer occur in bronchopulmonary tissue, the tumor mass formed by cancer tissue often irritates the respiratory tract, thus producing irritating cough.
2. hoarseness: hoarseness is also one of the common symptoms in the early stage of lung cancer. This is caused by the tumor mass compressing the recurrent laryngeal nerve.
3. Fever: Fever is a symptom of some patients with early lung cancer. This is mainly caused by cancer tissue necrosis, which is generally low to moderate fever. In this case, antibiotics are ineffective. However, when centripetal lung cancer grows in the bronchus and develops to lumen blockage or semi-blockage, it will lead to obstructive pneumonia and symptoms of general fever. This situation can be treated with antibiotics, but it is essential to remove the blockage, otherwise pneumonia will recur.
4. Chest pain: Chest pain is also a symptom of most lung cancer patients. If the cancer tissue is located near the pleura, there will be irregular dull or dull pain in the chest, while when the cancer tissue erodes the pleura, there will be severe chest pain, which will be aggravated when coughing and breathing deeply.
5. Hemoptysis: Hemoptysis is also an important symptom in the early stage of lung cancer. This is mainly due to the invasion of bronchial mucosa by cancer tissue, which leads to the rupture of capillaries. The amount and duration of expectoration are related to the degree of vascular damage caused by cancer tissue. Hemoptysis is generally persistent, characterized by bloodshot sputum or small blood clots. Bloodshot and blood clots are red or dark red.
6. Joint swelling and pain: Joint swelling and pain is also one of the important symptoms in the early stage of lung cancer. This symptom is mainly due to lung cancer tissue prompting some tissues of the body to produce some special enzymes, antigens and secretions, which are concentrated in some important joints of the body. This kind of swelling and pain mainly appears in the big joints, which is migratory and has nothing to do with weather changes. Many clubbing fingers appear at the same time.
7. Skin changes: Skin changes are early symptoms of lung cancer in some people. The main manifestations are prurigo, dermatomyositis, herpes zoster and other symptoms.
8. Endocrine disorder: Endocrine disorder is also a common symptom in the early stage of lung cancer. Mainly manifested as diabetes, myasthenia, muscular atrophy, edema of lower limbs and other symptoms, male patients will also have breast enlargement, testicular atrophy phenomenon.
9. Phrenic nerve paralysis: Phrenic nerve paralysis is also one of the important symptoms in the early stage of lung cancer. Phrenic nerve paralysis can lead to shortness of breath, chest tightness and other uncomfortable symptoms.
10. Pericardial invasion: Pericardial invasion is also an important symptom of patients with early lung cancer. This is mainly caused by cancer cells eroding the pericardium, which will lead to shortness of breath and arrhythmia in patients.
