Lung cancer is an epithelial malignant neoplasm that is localized to the bronchial glands, bronchial tree, or lung tissue.

Lung cancer: symptoms, causes, treatment

Lung cancer accounts for 85% of all diseases. The tumor is localized in the upper lobe of the lung - this is in 60% of cases, 30% of the lower part and 10% of the middle. Metastases mainly spread along 3 pathways: hematogenous, lymphogenous and implantation.

Why does lung cancer develop?

Risk factors and causes of lung cancer include:

  1. Smoking;
  2. Inhalation of air with substances containing carcinogens;
  3. Radiation.

Types of lung cancer

  1. Squamous;
  2. Small cell;
  3. Large cell;
  4. Glandular.

The clinical picture of lung cancer

The clinic of lung cancer, like all neoplasms, is similar. The most obvious signs are cough in lung cancer with purulent sputum, shortness of breath, fever up to subfebrile numbers, hemoptysis and chest pain.

Also, the symptomatology is characterized by the localization of the tumor process.

Central cancer

With this type, cancer develops in the large bronchus. The manifestation is early enough and well expressed due to impaired bronchial patency. In this case, ventilation of the lung or its segment is impaired. Lung cancer patients experience chest pain and progressive shortness of breath.

When a tumor grows in the bronchi, a cough with blood appears. After a while, cancerous pneumonia develops, which is manifested by purulent sputum, fever and shortness of breath. Quite often, cancerous pneumonia is complicated by hemorrhagic pleurisy.

If the tumor compresses the vagus nerve, then paralysis of the vocal muscles occurs, which is manifested by a hoarse voice.

Peripheral cancer

This type of cancer is asymptomatic in the early stages of development. After a while, sputum with blood appears, hoarseness of the voice, compression of the superior vena cava occurs. As the tumor grows, cancerous pleurisy appears, and the effusion is compressed.

How lung cancer is complicated

In a neglected state, various diseases of the affected organs join lung cancer: pulmonary hemorrhage, atelectasis, bronchial obstruction.

How is lung cancer diagnosed?

  1. General analysis of urine and blood;
  2. Blood chemistry;
  3. Chest x-ray;
  4. Examination of cytological sputum;
  5. Lymphatic vessel biopsy;
  6. Puncture.

How is lung cancer treated?

The main treatment for lung cancer is surgery. It is often combined with chemotherapy and radiation therapy. If it is impossible to carry out the operation, treatment is aimed at alleviating the patient's condition.
