Lung cancer is difficult to find in its early stages. To date, there is no standard screening process to find early stage lung cancer. Current available detection tests—chest x-rays and sputum tests—are not always accurate in finding early lung cancer.

|
What is NLST? The National Lung Screening Trial (NLST) is a lung cancer screening trial sponsored by the National Cancer Institute (NCI). Screening means testing people to detect a disease before it causes symptoms.
|
|
The National Cancer Institute (NCI), part of the National Institutes of Health, in partnership with the American Cancer Society, has enrolled its goal of 50,000 current or former smokers in the National Lung Screening Trial (NLST). The study, launched in September 2002, was designed to determine if screening with either spiral computed tomography (CT) or chest X-ray before the appearance of symptoms can reduce deaths from lung cancer. Although the trial has reached its 50,000 participant goal, it remains open at select sites to collect blood, urine and phlegm to help doctors identify biomarkers, or tumor markers, of lung cancer.
|
 |
The lack of effective methods for early detection of lung cancer is one of the reasons that most people diagnosed with lung cancer have advanced disease, and fewer than fifteen percent of these patients will survive more than five years.
|
 |
You may not notice signs of lung cancer in its early stages. In fact, many lung cancers are found through a chest X-ray taken for other reasons.
