Lung cancer bone metastasis

With the continuous development of modern industry, environmental pollution is becoming more and more serious. In addition, modern people generally travel by car, and the exhaust gas emitted by cars and factories containing harmful substances such as benzopyrene carcinogenic hydrocarbons seriously pollutes the air we need for survival. This has led to a continuous increase in the incidence of lung cancer. However, the lungs are the place where air is exchanged, and lung diseases can easily spread throughout the body.

Yes, the cancer cells of lung cancer patients can generally be transferred through the blood and lymphatic channels, which can cause cancer in multiple organs of the body, and the most common site of cancer is the bone marrow. Bone metastasis of lung cancer is the most common complication in patients with lung cancer. Below, let us understand the basic situation of bone metastasis of lung cancer.

Bone is a common site for lung cancer metastasis, and the incidence of lung cancer bone metastasis is related to the site and pathological type of the primary cancer. Adenocarcinoma has the highest incidence of bone metastasis, followed by small cell lung cancer and squamous cell carcinoma. The lesions of bone metastasis are mainly multiple. The most common sites of occurrence are: ribs, thoracic vertebrae, lumbar vertebrae, and pelvis; adenocarcinoma mainly metastasizes to the chest and pelvis. The main bone metastasis of lung cancer is adenocarcinoma, which often invades the ribs and thoracic vertebrae. The reason may be that adenocarcinoma often occurs in the periphery of the lungs, which can easily cause direct invasion and involve the ribs and thoracic vertebrae. In addition, tumor cells reach the bones through the blood circulation and tend to grow and multiply in the trunk bones containing red bone marrow, but rarely grow in the long bones of the limbs containing yellow bone marrow.

There are generally no symptoms in the early stages of bone metastasis, but bone isotope scanning can reveal diseased bones. The symptoms of bone metastasis are related to the location and number of tumor metastases. For example, chest pain caused by rib metastasis of lung cancer is often manifested as pain localized in the chest wall with clear tenderness points. Spinal cord metastases cause pain in the middle or lesion area of ​​the back, while bone metastases in the limbs or trunk cause localized pain in that area. Bone metastasis is not a direct cause of threat to the life of lung cancer patients, but if the tumor metastasizes to the body's weight-bearing bones such as the cervical vertebrae, thoracic vertebrae, lumbar vertebrae, etc., it can cause serious consequences such as paralysis. Therefore, patients with bone metastasis of lung cancer should be treated in a timely manner.

The above is the basic situation of lung cancer bone metastasis. From it we can see that lung cancer bone metastasis is actually a common complication of lung cancer. Moreover, bone metastasis of lung cancer will greatly increase the difficulty of treatment. Therefore, patients with lung cancer should receive timely treatment to avoid the occurrence of bone metastasis of lung cancer due to untimely treatment.
