What are the symptoms of lung tumors

Lung tumors are the most common respiratory tumors. Lung tumors are systemic diseases. Local treatments such as surgery and radiotherapy are difficult to achieve ideal results. Surgical treatment of lung tumors is prone to recurrence and metastasis, and postoperative care is particularly important. The best treatment period for lung tumors is the early stage, so it is important to understand the symptoms of lung tumors. So, what are the symptoms of lung tumors?

Lung cancer is a type of lung cancer, including lung cancer, but not necessarily lung cancer. Benign lung tumors refer to tumor cells that are similar to normal cells, but their tissue structure is different from the normal tissue structure, and they do not have the function of normal tissues. The cells proliferate abnormally and accumulate into masses to form tumor-like deformities. However, these cells proliferate slowly, do not spread throughout the body, and do not metastasize. Hamartoma is a more common benign tumor in the lungs. The name of the tumor indicates that it is caused by the disordered growth of tissue structure. Hamartoma can be composed of different proportions of cartilage, glands, smooth muscle, blood vessels, fat, and fibrous tissue in different patients. Sometimes only a small piece of tissue is taken for examination, which can be distinguished from benign tumors such as chondroma, leiomyoma, hemangioma, lymphangioma, lipoma, fibroma, neurogenic tumor, benign teratoma, etc.

In addition, there are rare benign mesenchymal cell tumors such as inflammatory pseudotumor, sclerosing hemangioma, tuberculoma, and sarcoidosis like tumor, bronchopulmonary cyst and other granulomatous diseases. In addition to lung cancer, lung malignancies include malignant lymphoma, lung carcinoma (squamous cell carcinoma and fibrosarcoma-like components), lung tumors, lung sarcomas (including leiomyosarcoma, fibrosarcoma, rhabdomyosarcoma, liposarcoma, angiosarcoma, chondrosarcoma, malignant papilloma-like hyperplasia, mesothelial cell carcinoma, malignant neurogenic tumors and malignant teratomas and hamartomas, etc.

What are the early symptoms of lung cancer?

Cough, mostly sporadic dry cough, little or no sputum, may contain a little white foamy sputum, often occurs after fatigue. Coughing time is not fixed.

Chest tightness is more common in the middle and late stages of lung cancer, but if the tumor is located near the pleura, chest pain may appear earlier, manifesting as irregular dull pain or dull pain. When the tumor directly invades the pleura, there may be severe chest pain, which is aggravated by coughing or breathing.

Hemoptysis or bloody sputum is caused by ruptured capillaries caused by tumor tissue necrosis and ulceration. The amount of hemoptysis or bloody sputum is generally small. In a few cases, tumor erosion of large blood vessels can cause large amounts of hemoptysis. If you experience this symptom, please go to the hospital for examination and medical treatment in time.

Fever. Fever is rarely an early symptom of lung tumors, but when tumor tissue necrosis occurs, it can cause low to moderate fever, which is ineffective for antibiotic treatment. When the lesion near the hilum of the central lung cancer causes bronchial obstruction or semi-blockage, it will lead to obstructive pneumonia and cause systemic fever. The temperature at this time is usually around 38°C. It can be treated with antipyretics and antibiotics, but if the obstructive lesions are not removed, pneumonia can attack repeatedly.

Joint swelling and pain, mainly in large joints, mainly in the ankle and second wrist joints, without wandering, and unrelated to weather changes, may occur locally, except for occasional periosteum thickening, most X-rays show no other abnormalities. Patients are reminded not to treat joint swelling and pain as joint disease.

Skin changes: a few people experience early itchy skin rash, dermatomyositis, herpes zoster, etc.

Endocrine system disorders. A small number of patients may also experience progressive muscle weakness, muscle atrophy, diabetes, lower limb swelling, male breast enlargement, testicular atrophy, etc. These are also common early symptoms of lung cancer.

Weight loss and emaciation are common symptoms of cancer. If your girlfriend suddenly loses weight and is unhappy about her own successful weight loss, the best thing to do is to go to the hospital for a check-up.

(1) Coughs are mostly occasional dry coughs with little or no sputum, and may contain a small amount of white foamy sputum, which often occurs after exertion. The coughing time is irregular and has nothing to do with body position.

(2) Hemoptysis or bloody sputum is caused by rupture of capillaries due to necrosis and ulceration of tumor tissue. The amount of hemoptysis and the duration of hemoptysis are related to the degree of vascular damage in the tumor tissue. It is usually persistent, with blood streaks or small blood clots in the sputum, and the blood is bright red or dark red. It is generally difficult to control with treatment. The amount of blood in hemoptysis or bloody sputum is generally small. In a few cases, tumor swelling corrodes large blood vessels, which can cause massive hemoptysis.

(3) Chest pain usually occurs in the middle or late stages of lung cancer. However, if the tumor is located around the pleura, chest pain may occur earlier and manifest as irregular dull pain or pain. When the tumor directly invades the pleura, there may be sharp chest pain, which worsens when coughing or breathing.

(4) Fever: Fever is rare in the early stage of lung tumors, but when the tumor tissue is necrotic, it can cause low or moderate fever, which is ineffective for antibiotic treatment. When the central lung tumor with lesions close to the hilum of the lung grows in the bronchus and develops to the point of obstruction or semi-obstruction of the bronchial lumen, it can cause obstructive pneumonia and systemic fever. At this time, the body temperature is generally around 38°C. The fever can be reduced by antibiotic treatment, but if the obstructive lesions are not removed, pneumonia may recur.

Through the above introduction, everyone should have understood the basic symptoms of lung tumors. Once symptoms of suspected lung tumors appear in life, you must pay more attention and go to the hospital for examination and treatment as soon as possible. In addition, everyone should pay more attention to lung care in life. Take precautions before going out in foggy weather to reduce the inhalation of dust mites, and eat more foods that clear and moisten the lungs.
