Clinical symptoms of lung cancer?

summary

Among the rare malignant tumors in the lung, the vast majority are peripheral type, and nearly half of the patients have no clinical symptoms. Lymphoma accounts for 41%, carcinosarcoma 20%, mucoepidermoid carcinoma 15%, sarcoma 18%, and the rest are malignant melanoma. Clinical symptoms of lung cancer?

Clinical symptoms of lung cancer?

Primary lung lymphoma non Hodgkin's lymphoma: rare primary lung lymphoma can occur in any part of the lung with normal lymphoid tissue, such as bronchial associated lymphoid tissue and mucosa associated lymphoid tissue, lung stroma or intrapulmonary and subpleural lymph nodes. Intrapulmonary and subpleural lymph nodes were more common, especially in patients over 25 years old. Lymphangiography confirmed that 18% of normal people had intrapulmonary lymph nodes in the lung parenchyma. Lung non Hodgkin's lymphoma stage (Table 1).

CT showed the following features: (1) pulmonary nodules < 1cm; ② Tumor or mass like fusion with or without cavity > 1cm; ③ Alveolar or interstitial exudation; ④ Pleura mass; ⑤ Peribronchial or perivascular thickening with or without atelectasis; ⑥ Pleural effusion; ⑦ Hilar or mediastinal lymph node hyperplasia. More than 68% of the patients can see the above three or more abnormal CT signs at the same time, which can be used to identify other diseases.

Secondary pulmonary lymphoma (44% ～ 70%) involves the lung, from anterior mediastinum or paratracheal mass to adjacent mediastinal lymph nodes, then to hilar lymph nodes, and finally to the lung. Pulmonary involvement can be directly diffused or separated nodules. Pleura, pericardium or chest wall are involved only when large lesions (refers to the mass of anterior mediastinum or paratracheal mass > 30% of the chest diameter). The above mainly refers to Hodgkin's lymphoma. About 50% of non Hodgkin's lymphomas involve the lung at autopsy, and the most common type is large cell type. It can also be seen in patients with recurrence or secondary to lung after treatment.

matters needing attention

Pay attention to eat more fresh vegetables and fruits, such as green, yellow, red vegetables, black fungus, almond dew, water chestnut, asparagus, lemon, red jujube, garlic and so on. Causal vegetables are rich in vitamin C, which is an anti-cancer substance and can block the formation of cancer cells; Can choose to enhance the body's immunity, help drugs inhibit cancer cell function of food, such as turtle, yellow croaker, sweet almond, walnut, jujube, mushroom, etc;
