The first official international guide recommends using chest CT as a screening test in people who have a high risk of developing lung cancer. This could save many lives, as it is estimated that each year more than one million people around the world because of this neoplasm.
A chest CT low radiation to detect the presence of tumor-when it is still in its initial phase-in 85% of cases
A study, which published The New England Journal of Medicine, and in which more than 53,000 smokers participated demonstrated the efficacy of low-dose chest CT versus traditional chest radiography, and thanks to this test is effective in reducing deaths lung cancer by 20%.
Low radiation CT is performed mainly in private schools because it is expensive, but if we look at the cost benefit that involves diagnosis of lung cancer when it can still be cured with ease, the balance is positive, since detecting the disease in advanced stages means more spending, more expensive treatment than stage initially, it is also inefficient, because even with the therapy most patients die within five years.
