A recommendation for older Canadians with a history of heavy smoking.
CT Scan
The Canadian Task Force on Preventive Health Care`s suggesting those aged 55 to 74, who are at high-risk of lung cancer, should be screened annually over three straight years using low-dose CT scans, not chest x-rays.
The group does not recommend screening for all other adults regardless of their age or smoking history.
It applies to current smokers or those who smoked one pack a day for 30 years or two packs daily for 15 years.
Recent studies, including a clinical trial, found a 15% reduction in lung cancer deaths among those screened with a CT scan compared to an x-ray.
The task force hopes the guideline will help doctors catch more lung cancers at earlier stages.
About 85% of lung cancer cases are linked to smoking.
The screening test is not for those who smoked for a couple years as teens.
The guideline’s published in the Canadian Medical Association Journal.
