Diagnosis
Patients can be diagnosed with lung cancer through the following methods:
Chest X-ray | X-rays can detect abnormalities in the lungs, and doctors will observe the location of any shadows or anomalies. |
Sputum Examination for Cancer Cells: | Sputum is examined under a microscope to check for the presence of cancer cells. https://heal-oncology.com/cancer/lung-cancer/ |
Bronchoscopy and Biopsy | After administering anesthesia to the patient, a doctor inserts a tube into the patient's airway to examine the bronchial mucosa and collect a small amount of live tissue for cancer cell analysis. |
Computer Tomography (CT) Scan | This uses X-rays and contrast imaging to reflect the condition of the lungs. Computer analysis of the images helps the doctor determine whether cancer cells are present. |
Low-Dose Lung CT Scan: | This is a medical imaging technique with lower radiation exposure. It uses X-rays to pass through the body and processes images through a computer. It offers a multi-angle and clear view of the internal structures or organs, providing specified sectional or 3D images.

Prevention
To prevent lung cancer, if you are a smoker, it is advisable to quit smoking as soon as possible. For non-smokers, it's important to avoid exposure to secondhand smoke. In daily life, you should also minimize contact with carcinogens. Common lung cancer screening tests include chest X-rays, sputum cell examination, and low-dose CT scans. Individuals with high-risk factors for lung cancer, such as smoking, can consult with healthcare professionals to assess whether they should undergo lung cancer screening. You can learn more about the "Heal Medical Lung Cancer Health Checkup Program" for lung cancer screening.
