Tumors of the lung

Primary tumors of the lung structure and clinical course can be benign or malignant.
Benign tumors are relatively rare and usually not clinically manifest themselves, are detected by preventive x-ray examination of patients.
The most frequent handsome, located in the peripheral zone of the lung tissue, less frequently, myoma, fibroma, lipoma.
Malignant tumors - sarcoma and cancer.
Sarcoma lungs are rare, they develop from connective tissue.

Cancer lung especially observed in the last 30-35 years mainly among men in large industrial cities. In the etiology of lung cancer play the role of various factors of the external environment: pollution of light dust containing blastomogenic substances (cobalt and others), Smoking. Tobacco smoke is a strong carcinogenic agent. Lung cancer is the frequency in second place after gastric cancer. Take lung cancer more often at the age of 40 - 60 years. Lung cancer can occur in large bronchus (equity, segment) - Central cancer or in the smallest bronchi, in the peripheral zone of the lung tissue - peripheral cancer.
The clinical course of the Central lung cancer is extremely diverse. First, it does not cause functional disorders of the diseased lung. Then appears dry, often hoarse, barking cough. With the growth and decay of the tumor starts to separate sputum with blood. A growing tumor gradually narrows the lumen of the bronchus, resulting hampered the normal ventilation of the relevant part of the lung. There is shortness of breath, chest pain on the affected side. Susceptible to infections, inflammation begins, increased body temperature. All this gives grounds and the patient and the doctor to think about the flu, especially if the temperature increase was preceded by a cooling of the body. Anti-inflammatory treatment soon leads to decreasing the temperature and improving the condition of the patient, but not for long. When x-ray examination of the patient detected changes in the lungs often interpreted as prolonged pneumonia. Despite anti-inflammatory treatment, improvement of patient's condition does not occur. Only a thorough clinical and x-ray examination allows to suspect the tumor in the lung. Peripheral lung cancer is growing slowly and for a long time makes no clinical manifestations, and only radiographically one can determine whether the tumor and make a diagnosis. The tumor manifests itself only after it has reached a considerable size, when squeezes pulmonary parenchyma, the pleura and patients may chest pain, shortness of breath and cough.
In addition to the primary cancer in the lung occurs metastatic cancer - singular and plural. Radiographically determined rounded, well defined shadows.
The lung cancer treatment is primarily surgical removal of the tumor with a proportional share or even with a whole lung. Possible radiation therapy (gamma therapy). Drug therapy is used for patients who cannot surgical care (Endoxan, 5-fluorouracil , and others). The prognosis is unfavorable.
Prevention. The patients, who often experience the symptoms of chronic inflammation of the lungs or the temperature rises to high numbers, should be directed at the cancer clinic for a full clinical examination and diagnosis.
To detect lung cancer at an early stage of great importance systematic x-ray examination of the population.
