What are the common clinical symptoms of lung cancer? Lung cancer patients have five clinical manifestations

Lung cancer is a disease of the respiratory system. Clinically, most patients with lung cancer have a history of smoking. Clinical research has found that patients with lung cancer of different causes have common clinical manifestations. The following are the five common clinical manifestations of lung cancer patients that experts will tell you about. Let us take a closer look.

Symptom 1: Fever: When the tumor blocks the bronchus, there is often an obstructive lung lobe with varying degrees. Mild cases only have low fever, while severe cases have high fever. The condition may temporarily improve after taking medication, but will relapse soon.

Symptom 2: Blood in sputum: Coughing is often accompanied by varying degrees of sputum. In some cases, blood may be present in the sputum. When tumor inflammation causes necrosis or capillary damage, there will be a small amount of bleeding, which is often mixed with sputum and appears intermittently or intermittently. Many lung cancer patients seek medical treatment because of blood in sputum.

Symptom three includes unexplained hoarseness and wheezing, obvious swelling on one side of the neck, smaller palpebral fissure on one side, drooping eyelids, and constricted pupils, etc., which may sometimes occur when lung symptoms are not yet obvious.

Symptom 4: Chest pain: 30% to 40% of lung cancer patients will experience pulmonary chest pain, which is generally intermittent, non-severe chest pain. It mainly manifests as dull pain or drilling pain, which can last from minutes to hours. If the tumor invades the pleura, the pain will be more severe, continuous and fixed. If chest pain recurs in the early stage of lung cancer, the recurrence of pain in the future indicates a poor prognosis.

Symptoms 5. Joint swelling and pain: The pain is mainly in the large joints, mostly the iliac joints, and secondarily the wrist joints. It is not migratory and has nothing to do with weather changes. Local swelling may occur. X-rays show no other abnormalities except occasional thickening of the periosteum. Some patients may have rod-like fingers (toes).

The above is just an overview of the common clinical manifestations of lung cancer patients. If you want to learn more about this disease, you can consult experts who study lung cancer. At the same time, the experts' explanations are simple and clear, which is also conducive to popularizing the knowledge of basic diseases and improving the physical fitness of citizens.
