Brief analysis of four common symptoms of lung cancer

Lung cancer is a malignant tumor with very serious symptoms. It is often caused by air pollution and causes serious damage to the patient's heart and lung health. What are the common symptoms of lung cancer ? Here are some common symptoms of lung cancer.

In general, common symptoms of lung cancer include:

① Cough: It is the most common symptom of lung cancer, and about 2/3 of patients have this symptom. It can be a mild dry cough or a severe cough, with varying amounts of sputum. However, in patients with chronic long-term coughs, once the nature of the cough changes, or the frequency of coughing increases or nighttime coughing occurs, be alert to lung cancer. Continuous, uncontrollable coughing is one of the most painful symptoms of lung cancer.

②Chest pain: 30% to 40% of patients experience pulmonary chest pain, which is generally intermittent and mild chest pain. The symptoms of this type of lung cancer are 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 early lung cancer, the prognosis is poor if the pain recurs later.

③ Hemoptysis: Half of lung cancer patients have this symptom. If a male smoker over 40 years old has blood in his sputum, blood streaks or small blood clots, the possibility of lung cancer is quite high. This is also a common symptom of lung cancer.

④ Fever: Most of the symptoms of this type of lung cancer are caused by inflammation due to bronchial obstruction and poor drainage caused by cancer. Early antibiotic treatment can restore body temperature to normal, but it is easy to relapse. For patients with larger tumors, necrosis occurs in the inflammatory center, and the absorption of toxins often causes a higher body temperature. Sometimes the fever is remitted every day for several months, and repeated anti-inflammatory treatment is ineffective. Once the tumor is removed, the body temperature immediately returns to normal. Lung cancer patients have no obvious inflammation in their bodies, but they have obvious fever, which is often caused by the tumor itself, the so-called "cancer fever", and the body temperature is often below 38°C. Male smokers over 45 years old who have long-term lung inflammation and fever and have poor treatment results should be especially alert to the possibility of lung cancer.

The above is an introduction to the common symptoms of lung cancer. I hope it will be helpful to everyone. Once the symptoms of lung cancer appear, you must go to the hospital for treatment in time to avoid missing the best time for treatment.
