Diagnosis of lung cancer

For those of you who experience symptoms of lung cancer such as ongoing coughing, coughing up blood, shortness of breath, and chest pain, you should immediately see a doctor.


Early detection of cancer can increase the success of the treatment process. The following are some tests that can be done to ensure a cancer diagnosis.

  • Sputum examination. The phlegm we remove when coughing can be examined in the laboratory with a microscope. Sometimes this examination can be used to see if there are cancer cells in the lungs.
  • Imaging test. The first diagnosis of lung cancer usually uses X-rays. X-ray imaging of the lungs can show an existing tumor. If an X-ray is suspected of lung cancer, further tests need to be done to confirm it.
  • CT scans can show abnormally small ones that cannot be seen with X-rays. By utilizing a CT scan, clearer and more detailed imaging can be obtained.
  • PET-CT Scan can show the location of active cancer cells. This imaging is usually done if the results of a CT scan show that there are cancer cells in the early stages.
  • Biopsy or sampling of lung tissue. This procedure is done after the imaging test and shows that there are cancer cells in the chest. The doctor will take samples of tissue cells from the lungs.
 

    Lung Cancer Stadium

     
    • Stage 1. The cancer is still in the lungs and has not spread to the surrounding lymph nodes. The size of the tumor at this stage is still below 5 cm.
    • Stage 2. Tumors measuring more than 5 cm. However, regardless of size, the tumor can be said to enter stage 2 if cancer has spread to nearby lymph nodes, the muscles, and surrounding tissue, and the respiratory tract (bronchi), cancer causes the lungs to collapse (constrict), there is more than one tumor small in one lung.
    • Stage 3. At this stage, there are cancer cells that have spread to lymph nodes that are far away from the lungs or the cancer attacks other important body parts such as the esophagus (esophagus), trachea, or the main blood vessels in the heart.
    • Stage 4. Cancer has spread to both the lungs or other organs far from the lungs such as the brain and liver. In addition, it can be categorized as stage 4 if cancer causes a buildup of fluid in the lungs.
