X-ray exam is used to determine if there are lung nodules. Then you have to determine if they are malignant.
The computed tomography of the thorax (CT scan chest cost in Delhi) is a method of imaging by X-rays, which is commonly used for the diagnosis of lung diseases and is the only proven to reduce the number of deaths per test lung cancer, associated with early detection of the disease. The chest CT is indicated in all patients in which a pulmonary pathology is being studied. In recent years, it has also been shown to be effective as a screening method in lung cancer, similar to mammography for breast cancer screening.
It is not an annoying examination and practically does not have risks, except those related to the minimum radiation exposure. The CT, basically takes many pictures of the inside of the body using x-rays, allows to examine in a few minutes the entire thoracic cavity, so, including the necessary preparation, takes between 15 and 30 minutes.
According to the specialist, it is recommended as a lung cancer screening to perform a normal initial chest CT scan and subsequently a low-contrast, no-dose chest CT scan in the follow-up studies.
Tests and studies to detect lung cancer
If your doctor thinks you might have lung cancer based on the results of a screening test or because of the symptoms you have, other tests and tests will be done to confirm the suspicion.
Medical history and physical examination
Your doctor will ask about your medical history to learn more about any symptoms you have and possible risk factors. You will also be tested for signs of lung cancer or other health problems.
If the results of the history and physical examination suggest that you may have lung cancer, more tests will be done.
Tests to detect lung cancer
For this test, a sample of mucus that coughs from the lungs (sputum) is examined under a microscope to determine if it contains cancer cells. The best way to do sputum cytology is to obtain the samples early in the morning for three consecutive days.
If you have symptoms that can cause lung cancer, the chest x-ray will often be the first study that the doctor will order. Simple chest x-rays can be done in imaging centers, hospitals, and even in some doctors' offices. If something looks suspicious, your doctor may order other tests.
A CT (CT scan chest cost in Delhi) uses X- rays to produce detailed cross- sectional images of the body. Instead of taking a picture, like conventional radiography, CT scans take many pictures while a device rotates around you while you lie on a stretcher. Then, a computer combines these photographs to form cross sectional images of the part of the body being studied.
Lung tumors are more likely to be detected on computed tomography (CT) than on conventional chest radiographs. CT scans can also show the size, shape, and position of any tumor in the lung, and can help find enlarged lymph nodes that may contain cancer that has spread from the lung.
