What symptoms should be considered as lung cancer? 4 abnormal manifestations, be careful of lung cancer

Although lung cancer is a very common cancer, not many people really know about it. Even if a large number of people have lung cancer, they may not know it because they do not know the symptoms of lung cancer. Therefore, it is very important to understand the symptoms of lung cancer so that the disease can be detected as early as possible.

1. Facial edema and neck swelling: The clinical manifestation of superior vena cava obstruction syndrome is caused by various causes of complete or incomplete superior vena cava obstruction, which results in obstruction of blood return in the superior vena cava, thus causing edema of the upper limbs, neck, face and superficial varicose veins in the upper body. Tumors, inflammation of the mediastinum and thrombosis of the blood vessels themselves can all be the causes, among which bronchial lung cancer is the most common.

2. Difficulty in swallowing: Cancerous lungs invade or compress the esophagus, which can cause difficulty in swallowing hard or large foods. The symptoms are similar to those of esophageal cancer.

3. Morning headache and vomiting: This is a manifestation of lung cancer metastasis to the brain. Most headaches occur at night and in the early morning, especially in the morning when the pain is most obvious, and often wake up from a deep sleep. After getting up and doing some light activities, the headache gradually eases or disappears, so it is called "morning headache". In the early stage, it is often intermittent, with throbbing pain and distending pain, and each attack lasts for several minutes or hours. As the tumor continues to grow, the pain may turn into localized, continuous and gradually worsening pain, accompanied by projectile vomiting, and the headache symptoms worsen when coughing, sneezing, or defecating.

4. Mental abnormality: There are many patients who seek medical treatment for mental symptoms such as tremors, convulsions and abnormal expressions. This is because small cell lung cancer causes an increase in antidiuretic hormone, which causes water retention, dilutional hyponatremia and hypoosmotic encephalopathy. When lung cancer metastasizes to the frontal lobe of the brain, it can destroy the mental activities of the frontal lobe and cause abnormal mental manifestations such as excitement, agitation, depression, repression, amnesia, and fabrication.

5. Abnormal unilateral limb movement: When lung cancer metastasizes to the brain, neurological symptoms such as headache, vomiting, coma, aphasia, and hemiplegia may occur. Because the lung symptoms are not obvious, they are often misdiagnosed as brain diseases such as stroke and brain tumors. If you have the various lung cancer symptoms described above in your life, you must be vigilant, because you may have lung cancer. However, it is best to go to the hospital for an examination and then receive treatment after the condition is confirmed. Don't take medicine blindly, which is not good for your condition.
