Lung cancer metastasis

Introduction to lung cancer metastasis In the advanced stage of lung cancer, the transfer of various organs can occur, which can cause corresponding symptoms, often causing great pain to the patient and even threatening life. Lung cancer is the most common malignant tumor in the respiratory system. The incidence of brain metastases in lung cancer can reach 35% to 50%. basic knowledge Sickness ratio: 0.05% Susceptible people: no specific population Mode of infection: non-infectious Complications: nausea and vomiting

Causes of lung cancer metastasis

Causes of lung cancer brain metastasis: This is because there is a large number of anastomotic branches between the cerebral blood vessels and the vertebral artery and the static arterial plexus supplying the brain, so that the lung cancer cells can pass through the heart, the carotid artery and the brain without filtering through the pulmonary capillaries. And blood transfer occurs. Headache, vomiting, visual impairment, and personality and temper changes in patients with brain metastases from lung cancer may be caused by intracranial hypertension or damage to the brain caused by lung cancer metastasis to the brain.

The cause of bone metastasis of lung cancer may be that lung cancer directly invades the chest bones such as ribs, sternum, and scapula, which may cause a significant increase in breast bone metastasis. It may also be that cancer cells are easily transferred into the vertebral body through the vertebral venous system, thus making the spine common. Transfer site. Another possibility may be related to blood supply and lymphatic drainage in high-risk areas of bone metastasis and the biological behavior of cancer cells of various pathological types.

Lung cancer metastasis prevention

Early detection and early diagnosis and early treatment.

Lung cancer metastasis Complications, nausea and vomiting

Complications such as vomiting and muscle weakness may occur.

Symptoms of lung cancer metastasis Common symptoms Local tenderness, headache, vomiting, side limb paralysis, blurred vision

Lung cancer brain metastases are often misdiagnosed as cerebrovascular disease, primary brain tumor, tuberculous meningitis or intracranial hypertension with headache, vomiting, facial paralysis, hemiplegia, blurred vision, aphasia, and muscle weakness.

About 50% of lung cancer patients will eventually have multiple bone metastases. There is usually no symptoms in the early stage of bone metastasis, and bone isotope scans can detect diseased bones. The symptoms of bone metastasis are related to the location and quantity of tumor metastasis. For example, chest pain caused by rib metastasis of lung cancer is often manifested as pain with a clear tender point in the chest wall.

Examination of lung cancer metastasis

A CT scan of the brain can be performed.

Diagnosis and differentiation of lung cancer metastasis

Diagnosis can be performed based on clinical performance and laboratory tests.
