Lung cancer in non-smokers can be harder to detect early

Lung cancer in non-smokers can be harder to detect early

Pope Leo XIV had an early lung adenocarcinoma and underwent surgery to remove a nodule and the lower lobe of his right lung.

People who have smoked fewer than 100 cigarettes in their lifetime are classified as non-smokers in the account, and this group makes up up to 20% of lung cancer diagnoses.

Lung cancer in non-smokers is more often adenocarcinoma, while smoking is more closely linked to small-cell and squamous-cell cancers.

Non-smokers are diagnosed at an average age of 67, compared with 70 for smokers, but their cancer is often detected later because symptoms may not raise suspicion and they are not included in screening programs for people with a substantial smoking history.

Some non-smokers’ tumors have changes such as EGFR or ALK, which can help doctors choose targeted treatments.

In the United States, new lung cancer cases have fallen by an average of 2% a year since 2014, while deaths have declined by about 4% a year.
