What are the dangers of lung cancer metastasis

Lung cancer is one of the most common malignant tumors. Once cancer cells metastasize and spread, it usually means that the patient's condition has developed to the late stage, which will cause great harm to the patient. Let's take a look at the hazards of lung cancer metastasis.

Lung cancer, also known as bronchial tumor, is one of the most common malignant tumors. The symptoms of lung cancer are closely related to factors such as whether the tumor has metastasized, whether it compresses adjacent organs, location, size, etc. Early symptoms include cough, hemoptysis, chest pain, fever, joint swelling and pain, etc. Once cancer cells metastasize and spread, it usually means that the patient's condition has developed to the late stage, which will cause great harm to the patient.

The dangers of lung cancer brain metastasis

Small cell lung cancer and adenocarcinomas are prone to brain metastasis. The main symptoms of patients are headache, vomiting, visual impairment, etc. Vomiting often occurs when the headache is severe, and visual impairment often indicates that the tumor has compressed or invaded the optic nerve. In addition to the above symptoms, patients with lung cancer brain metastasis will also experience symptoms such as increased blood pressure, slow pulse, diplopia, paroxysmal blackouts, impaired consciousness, etc. In severe cases, respiratory arrest may even occur, posing a serious threat to the patient's life.

The harm of lung cancer bone metastasis

About half of patients with advanced lung cancer will have bone metastases in multiple parts of the body. There are usually no obvious symptoms in the early stages, and bone isotope scanning can detect diseased bones. As the disease progresses, patients will show a series of symptoms of bone metastasis. The symptoms of bone metastasis are related to the site of tumor metastasis. For example, spinal cord metastasis can cause pain in the middle of the back or the site of the lesion; lung cancer rib metastasis often manifests as chest pain, pain that is localized in the chest wall and has clear tenderness points. Bone metastasis is not a direct cause of threat to the patient's life, but if the tumor metastasizes to the lumbar spine, thoracic spine, cervical spine and other weight-bearing parts of the body, it may cause paralysis, causing great inconvenience to the patient's life.

The harm of lung cancer liver metastasis

Clinically, about 28% of lung cancer patients will have liver metastasis, which is mainly manifested by persistent distension and pain in the liver area, accompanied by loss of appetite, indigestion and other manifestations of liver damage. Liver metastasis can be single or multiple nodular metastatic foci, which are tumor cells of primary lung cancer that shed and invade the liver through the blood circulation.
