The analysis showed that between these ages, a higher proportion of patients were diagnosed at a late stage of lung cancer compared to patients aged 65-69, researchers said.
People in their 70s are more likely to be diagnosed with early stage disease, they said.
"Our results show that younger patients in their 50s and early 60s are more likely to be diagnosed with advanced lung cancer compared to patients in older age groups," said David Kennedy from Cancer Research UK.
Previous research shows that older patients may be diagnosed with certain cancers such as bladder and lung at an earlier stage compared to younger patients, but this is the first time this relationship has been explored using lung cancer data at a national level.
"The research can lead to a better understanding of who is at an increased risk of different cancers. It can help target resources to the right groups in helping to improve cancer survival," said Julie Sharp from Cancer Research UK.
