Early symptoms of lung metastasis from colon cancer

Colon cancer refers to a malignant tumor disease that occurs in the colon. Pulmonary metastasis of colon cancer refers to the spread of the tumor to the lung tissue. The early symptoms of pulmonary metastasis of colon cancer include coughing, expectoration, chest pain, etc. The specific symptoms vary from person to person.

1. Cough: When cancer cells invade lung tissue, it will directly affect the normal metabolism of the lungs, causing secretions to accumulate and the body to produce a stress response, resulting in coughing symptoms.

2. Coughing up phlegm: Patients are more likely to have foamy sputum, and blood may appear in the sputum due to mucosal damage during coughing.

3. Chest pain: After colon cancer metastasizes to the lungs, the cancer cells invade the lung tissue and compress the lung system, which will directly affect the blood circulation and metabolism of the lungs, thus causing chest pain symptoms.

Some patients may also experience more obvious symptoms such as shortness of breath, difficulty breathing, fixed abdominal mass, weight loss, abdominal pain, blood in the stool, etc. If colon cancer has already occurred, you need to seek medical examination and treatment as soon as possible to avoid the spread and metastasis of cancer cells.
