What are the symptoms of lung cancer that need attention? Lung cancer patients should seek medical attention immediately if they have 4 symptoms

We often see some lung cancer patients who come to the hospital for treatment in the middle or late stages. In fact, it is not that they do not want to receive treatment in the early stages, but it is difficult to detect lung cancer in the early stages, and it is very difficult to cure when it is discovered in the middle or late stages. So what symptoms of lung cancer should be taken seriously?

1. Dysphagia:

What symptoms of lung cancer should be taken seriously? First of all, dysphagia may occur. Cancerous lungs invade or compress the esophagus, which can cause difficulty in swallowing hard or large pieces of food, and the symptoms are similar to esophageal cancer.

2. Facial swelling and neck swelling:

Secondly, if the patient has edema in the face and neck, we may need to pay attention, because the clinical manifestations of superior vena cava obstruction syndrome are complete or incomplete obstruction of the superior vena cava caused by various causes, resulting in obstruction of blood return in the superior vena cava, thereby causing edema of the upper limbs, neck, face and superficial varicose veins in the upper body.

3. Morning headache and vomiting:

If the patient has headache and vomiting among the symptoms, you need to pay attention. It 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. People are often awakened by the pain in a deep sleep. After getting up and doing light activities, the headache gradually eases or disappears, so it is called "morning headache".

4. Mental abnormality:

What symptoms of lung cancer require attention? Experts say that there are many patients who seek medical treatment with mental symptoms such as tremors in the limbs, convulsions, and abnormal expressions. This is because small cell lung cancer causes an increase in antidiuretic hormone, which leads to water retention, dilutional hyponatremia, and hypoosmolar encephalopathy.

There are many habits and behaviors in life that we don’t pay attention to when they occur, and we always think that they are not a big deal. In fact, these minor illnesses may be precursors to lung cancer. Therefore, if we find conditions similar to those described above, we must actively do a comprehensive examination to prevent the condition from worsening.
