More than half of lung cancer diagnoses occur at stage IV.
Measuring lung cancer control
Lung cancer is the leading cause of death for both men and women in Canada. While considerable progress has been made in the management of many other types of cancer, the survival rate for lung cancer has improved only slightly over the last 15 years.. This is primarily because the majority of lung cancers are diagnosed in an advanced stage. Although emerging evidence has shown that screening current or former heavy smokers decreases mortality rates, more investigation is still needed in the areas of over-diagnosis, net benefit versus harm, and at-risk populations to screen.
