Within the framework of this program, researchers around the world have tested more than 31,000 high-risk individuals (addicted or ever addicted to smoking) from 1993 to 2005. As a result, 92% of those affected Diagnosed lung cancer has an additional 10-year chance of life if diagnosed early with CT scan and surgical intervention immediately after diagnosis.

Studies conducted in the 1970s have demonstrated that regular chest X-ray photography does not improve survival, because this technique often causes false alarms. Until 1990, this technique was replaced by CT scan technology. The scanner uses a special X-ray device to capture information from different angles, then process this information by computer to create a cut-off image of many tissues and organs. check.

Lung cancer is the disease with the highest mortality rate in the world. According to studies, this year there will be 1 million people worldwide diagnosed with this disease. Most patients will die due to the late diagnosis for effective treatment.
