What are the symptoms of lung cancer

What are the symptoms of lung cancer?

The occurrence of dry cough does not mean the presence of lung cancer, but relatively speaking, the probability of developing cancer is relatively high, and the earliest symptoms are not very obvious, so it is easy to be confused by everyone and miss the best treatment opportunity.

1. No symptoms in the early stage

Nearly two-thirds of lung cancer patients were in stage III or IV at the time of consultation. Clinical examination results of 95% of patients showed that primary tumor, metastasis, systemic symptoms or tumor-related symptoms were the main symptoms of the patients.

2. Obvious chest pain

Studies have shown that early lung cancer may cause significant pain in bones, joints and nerves. This pain is not continuous but may be intermittent. Early lung cancer lesions compressing the brachial plexus can cause pain in the ipsilateral shoulder and arm, making it impossible to lift the arm, and can directly radiate to the shoulder and other parts, accompanied by significant muscle atrophy.

3. Obvious fever

Male smokers over 45 years old who have symptoms of pneumonia may also have a fever. At this time, they can basically return to normal after antibiotic treatment, but they are also prone to relapse. At this time, you should pay attention to the possibility of lung cancer.

After lung cancer, it will cause bronchitis and grass obstruction. Mild patients will also have a low fever. If the situation is more serious, a high fever may occur. Although medication can improve the condition, the probability of recurrence is very high, and the body temperature basically exceeds 39 degrees.

4. Mild chest tightness

Lung cancer often causes chest tightness in the early stages, often with mild chest tightness. If it involves the parietal pleura or directly invades the chest wall, it can cause persistent pain. It should be emphasized that there are no special symptoms in the early stages of lung cancer. If the respiratory symptoms or primary symptoms worsen after more than 2 weeks of treatment, we should be alert to the possibility of lung cancer. These diseases can only bring more advantages when they are initially treated.
