What are the systemic symptoms of lung cancer patients? Several systemic symptoms of lung cancer

This is the first symptom in 20% to 30% of cases. There are two reasons for fever caused by lung cancer. One is inflammatory fever. When central lung cancer tumors grow, they often block the segment or bronchial opening first, causing obstructive pneumonia or atelectasis in the corresponding lobe or segment, resulting in fever, but the temperature is usually around 38°C.

The occurrence of cancer can almost destroy a person or a family. Lung cancer is one example. The occurrence of lung cancer is generally closely related to the patient's surroundings, especially smoking, which is disgusting. Stay away from it if possible. The following are the systemic symptoms of lung cancer patients:

1. Fever

This is the first symptom in 20% to 30% of cases. There are two reasons for fever caused by lung cancer. One is inflammatory fever. When central lung cancer tumors grow, they often block the segment or bronchial opening first, causing obstructive pneumonia or atelectasis in the corresponding lobe or segment, resulting in fever, but the temperature is mostly around 38°C and rarely exceeds 39°C. Antibiotic treatment may be effective and the shadow may be absorbed, but due to poor drainage of secretions, it often recurs. About 1/3 of patients may repeatedly develop pneumonia in the same part within a short period of time. Peripheral lung cancer often causes fever in the late stage due to inflammation caused by tumor compression of adjacent lung tissue. The second is cancer fever, which is mostly caused by the absorption of tumor necrotic tissue by the body. This type of fever is ineffective with anti-inflammatory drugs, but hormones or indole drugs have a certain effect.

2. Weight loss and cachexia

In the late stage of lung cancer, due to loss of appetite caused by infection and pain, increased consumption caused by tumor growth and toxins, and increased levels of cytokines such as TNF and Leptin in the body, severe weight loss, anemia, and cachexia may occur.
