What are the symptoms of early lung tumors

Early lung tumors may present with symptoms of emaciation, usually accompanied by coughing, chest pain, bloody sputum, difficulty breathing, and fatigue. The early symptoms of lung tumors are mainly caused by factors such as tumor compression, metabolic abnormalities, immune response, endocrine disorders, and nutrient depletion.

proliferation of tumor cells can accelerate the body's energy consumption and significantly increase the basal metabolic rate. The release of substances such as tumor necrosis factor can interfere with normal metabolic processes, leading to accelerated muscle breakdown. This abnormal metabolic state can cause sustained weight loss.

3. Immune Response

The body's immune response to tumors may trigger systemic symptoms such as low-grade fever and night sweats. The excessive release of inflammatory factors can affect the appetite center, leading to a decrease in food intake. Long term immune activation can consume a large amount of energy and worsen the degree of emaciation.

insufficient nutrient intake due to decreased appetite and difficulty eating.
