Symptoms and signs of bone metastasis from lung cancer

summary

I heard that my friend had lung cancer. I went to visit him yesterday. It's very distressing to see his haggard face. The doctor said that he has ascites, which has been under control recently. The patient's recovery is very good, and his mentality is also very good. Now let me talk about the symptoms of bone metastasis of lung cancer.

Symptoms and signs of bone metastasis from lung cancer

Symptom 1: there are no symptoms in the early stage of bone metastasis, and bone isotope scanning can find 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 mostly manifested as pain with definite tenderness points and limited chest wall.

Symptom 2: spinal cord metastases cause pain in the middle of the back or the lesion, while bone metastases in the limbs or trunk cause localized pain.

Symptom 3: bone metastasis is not the direct cause of threatening the life of lung cancer patients, but if the tumor is transferred to the body's load-bearing bone, such as cervical spine, thoracic spine, lumbar spine and other parts, it can cause serious consequences of paralysis. Therefore, patients with bone metastasis of lung cancer should be treated in time.

matters needing attention

Bone metastasis of lung cancer refers to the metastasis of lung cancer cells to the corresponding bone through blood. Bone is the most common site of lung cancer metastasis. The incidence of bone metastasis of lung cancer is related to the location and pathological type of primary cancer. Adenocarcinoma had the highest incidence of bone metastasis, followed by small cell lung cancer and squamous cell carcinoma. Most of the metastatic lesions were multiple. The most common sites were ribs, thoracic vertebrae, lumbar vertebrae and pelvis. The main bone metastasis of lung cancer is adenocarcinoma, which often invades ribs and thoracic vertebrae. The reason may be that adenocarcinoma often occurs in the periphery of the lung, causing direct invasion and involving the ribs and thoracic vertebrae. In addition, tumor cells can reach bone through blood circulation, and grow and propagate easily in trunk bone with red bone marrow, but less in long bone of limbs with yellow bone marrow.
