What reduces lung cancer mortality?

53,000 people smoking or being heavy smokers in the past were part of the survey. But they became two parties. One group had a hole in the lungs once a year, while the other group had a lung scan once a year.

The scan was found to detect a lung tumor earlier than an X-ray. Medical doctor Christina Berg, near the US National Cancer Institute, said they have clear evidence that lung cancer mortality is the lowest in the scanning group.

Smokers of middle age and old have been examined either by scanner or by lung X - ray once a year.

They were followed for 5 years, and 354 of the examination scans died from lung cancer compared with 442 of those who died in the lung group who had conducted tests with the gythag. This showed that the mortality rate was 20.3% for those who had developed lung scans.

Researchers believe that this discovery can save thousands of lives.

lung cancer is the world's number one killer, killing about a million and two hundred thousand people a year.

If lung cancer is detected early, it can be treated successfully. The problem is that at first it is completely free of symptoms, and when symptoms appear, then cancer has already spread.

Only 15% of cancer patients live 5 years or longer. The fight against smoking is said to be principal in preventing lung cancer.
