Lung cancer tests
When there was a suspicion of cancer, the question arises: how to make tests showing lung cancer.
What are the tests for the presence of a malignant tumor? How can the lungs be healed when anxiety symptoms appear? Timely testing will help to avoid the risk of disease.
How are tests done for suspected cancer?
In order to determine any disease, a general blood test is done, while the laboratory assistant determines the violations in its composition.
A blood test consists of the following actions:
- Biochemical - in order to find out how the increase in globulin occurs;
- Study of oncological markers for the presence of neuroenolase, cytokeratin (the same as squamous cell carcinoma);
- A blood test for lung cancer shows a decrease in serum albumin levels;
- Tumor markers are considered effective methods for determining the extent of disease;
Contraindications to analyzes
Usually, the symptoms of the disease appear in the late stages, but what tests are taken for lung cancer, patients most often do not know. The most common diagnostic methods help diagnose cancer at an early stage.
At the slightest suspicion of a tumor, the patient needs to take all possible measures for a medical examination. And if the tests carried out gave confirmation of cancer, in order to make sure that the diagnosis is correct, you need to conduct the following examinations:
- A lung biopsy, during which some tissue is removed for examination under a microscope. As a rule, such an analysis is prescribed after a tumor is detected on a chest x-ray or using computed tomography;
- Mediastinoscope - palpation or visual examination of the upper and lower lymph nodes of the trachea. To do this, use a special mirror with an LED;
- Analysis of lung function;
- Ultrasound.
By doing this, it is possible to determine whether the cancer has affected organs near the lungs. A blood test for a disease is the most popular diagnostic method. But in this case, specific changes are not observed, and leukocytosis appears later. In a biochemical study of blood, a reduced level of serum albumin is found and alpha-2 and gamma globulins are increased.
