A cancer charity concluded that there has been a massive increase in the number of deaths caused by lung cancer in Scotland.

More than 1.3 million cases of lung cancer are registered each year and almost 80% people die within a year of treatment. People detected in the early stages of cancer survived it gradually.

Although smoking is largely responsible for causing lung cancer but nearly 4,000 patients, who never smoked a cigarette had lung cancer. A large number of people die due to delayed treatment or insufficient services provided by the hospitals.

UK experts claim that a lot of people can be saved with the help of CT scans as it helps in detecting the cancer early.

Dr. Michael Peake, the national clinical lead for lung cancer at NHS Cancer Improvement, said: "This is the first time that lung cancer screening has shown a positive impact on survival rates. Targeted screening, together with increased awareness about the symptoms, and improved standards of hospital care could save 10,000 lives a year".

A study on 50,000 people conducted by the US National Cancer Institute (NCI) concluded that lung cancer death rate has declined up to 20%. The participants were checked with CT scans. Researchers added that 70% of lung cancer sufferers can survive for 5 years if operated on time.
