Diagnostic Of Lung Cancer Part 2
6. Cytology Sputum microscopy is examined a sample of sputum to see if it contains cancer cells. * Needle biopsy: A needle is inserted into the mass while the lungs are displayed on a computer tomograph. Then a sample of the mass and observed through a microscope for cancer cells.
7. Bronchoscopy: We introduce a flexible, lighted tube through the mouth into the bronchi. This procedure can help find tumors located centrally or obstructions in the lungs. Also be used to take biopsies or remove fluids to be examined with a microscope to see if they contain cancer cells.

Diagnostic Of Lung Cancer Part 1
A biopsy of lung tissue serves to confirm or refute a possible diagnosis of cancer as well as provide valuable information to determine the appropriate treatment.
If it is eventually detected lung cancer, additional tests will be conducted to determine how far the disease has spread, including:
1. Medical history and physical examination: The medical history was recorded risk factors and symptoms of the patient. The physical examination provides information about signs of lung cancer and other health problems.
Test to Detect Lung Cancer
- Chest radiograph with which you can see any mass or spot on the lungs and reasonably set the probability of being a cancer. This test is performed in two projections, one front and one in profile. For more than 95% of cancer cases their results are abnormal.
- TAC: It consists of an X-ray emission from different perspectives and with that seen throughout the body. It is a simple test which usually lasts more than 15-30 minutes. This is more sensitive than radiography and it detects more early-stage cancer. It also serves to check for metastasis to other organs: liver, adrenal glands, brain and so on. It is the most widely used imaging test and profitable in the study of this disease. However, sometimes required to complete the study of CT with other more sensitive tests for specific sites of lung cancer: magnetic resonance imaging (MRI) brain or spine, liver ultrasound, bone scan and so on.
- Magnetic resonance imaging is used to make detailed cross-sectional images. This technique uses magnetic fields and spectra emitted by phosphorus in body tissues and becomes the image. With it you can see the tumor vasculature. They are more accurate images with which one can observe the spread of cancer to the brain or spinal cord. It is often not too useful for exploring the lungs.
Diagnostic Of Lung Cancer
Only 15% of lung cancer is diagnosed in early stages, this is because the symptoms do not appear until the disease is advanced. If no lymph node involvement at the time of surgery, the survival rate five years is 50%. Considering all cases globally, the survival rate is reduced to 14%.
There are various diagnostic tests that visualize the lung tumors at different stages.
The doctor will use a method to detect cancer if there is prior suspicion. The patient’s medical history is the first to be conducted to assess personal and family history. The doctor will ask about the existence of cancer and other diseases in the family, snuff consumption, environmental or occupational exposure to substances that produce lung cancer and respiratory disease or any other suffering the ill.
The physical examination will take into account the symptoms that the patient concerned, and with it, it can obtain data that can help diagnose any disease.
