Dr Ian Lewis, Director of Research and Policy at Welsh cancer charity Tenovus, says Public Health Wales and the Welsh Government should "promote the signs and symptoms of lung cancer, so that people present earlier at the GP and are more likely to receive successful treatment".
He says that, in addition to a public awareness campaign, there should be more investment in promoting healthier lifestyles, and particularly quitting smoking.
Lung cancer is the biggest cancer killer in Wales, accounting for 22 per cent of all cancer deaths - and a recent European survey ranked Wales 28th out of 29 countries for survival rates.
