What are the obvious symptoms of lung cancer? Several clinical symptoms of lung cancer

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.

Lung cancer is actually a disease that makes many people very painful. Most lung cancer patients are already in the middle and late stages when the disease is discovered. Therefore, the treatment time of the disease is very critical. To treat the disease, everyone should first understand the symptoms of lung cancer and go to a regular hospital for treatment as soon as possible. Below I will introduce several clinical symptoms of lung cancer.

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.

Nowadays, there are more and more patients with lung cancer, which has a lot to do with our living and eating habits. As a patient with lung cancer, the most important thing is to grasp the best treatment time. At the same time, patients should also adjust their diet and do a good job of their own care.
