Lung Cancer diagnosis
The tests used to diagnose lung cancer have two purposes. First, they help the oncologist determine the exact type of tumor you have. On the other hand, they allow determining what phase it is. An accurate diagnosis allows determining which will be the most appropriate treatment.
The following are the most commonly used techniques to diagnose lung cancer:
Imaging tests: Imaging tests are used to determine the size, shape, and location of the tumor. They are also used to determine if there is a distant metastasis in some other organ or lymph node of the body
- Chest x-ray
- Computed axial tomography
- Positron emission tomography
- Magnetic resonance
Procedures for staging and obtaining samples: Staging procedures are the diagnostic methods that allow the specialist to see directly the lung and nearby areas and, in addition, obtain samples of lymph nodes or other tissues to be able to analyze them later (biopsy and/or cytology).
- Biopsy with endobronchial ultrasound
Analysis of tissue samples: Tissue samples obtained through the procedures described above are analyzed by a pathologist to determine if cancer cells exist. We must remember that the definitive diagnosis of cancer is provided by the histological study of the tissue obtained by biopsy or cytology.
