What are the symptoms of lung metastasis from colorectal cancer

Symptoms of colorectal cancer metastasis to the liver and lungs. As the saying goes, health is the foundation of revolution. Without a healthy body, our normal life and work will be greatly affected. So no matter how busy you are, you must pay attention to your health. Colorectal cancer is one of the more common malignant tumors in society today. As the disease progresses, liver and lung metastasis will occur. The following is an introduction to the symptoms of colorectal cancer lung metastasis. Let's take a look.

Early lung metastasis of cancer usually has no obvious respiratory symptoms. If the lung lesions are extensive, dry cough, blood in sputum and dyspnea may occur. When lung metastasis invades the pleura, main bronchi or adjacent structures, the same symptoms as primary bronchial lung cancer may occur, such as cough, blood in sputum, chest pain, chest tightness, shortness of breath, etc. If accompanied by mediastinal metastasis, the patient may show symptoms of hoarseness, superior vena cava syndrome, diaphragmatic paralysis and esophageal or tracheal compression. Occasionally, the tumor may cause acute pulmonary embolism, which manifests as progressive dyspnea.
The main distant metastasis of colorectal cancer is the liver. Symptoms of liver metastasis include 20% to 25% of newly diagnosed colorectal cancer cases, and 40% to 50% of colorectal cancer cases that have undergone surgical resection will eventually develop liver metastasis. Symptoms of liver metastasis include jaundice, ascites, edema, etc.
