There are not enough specialist surgeons to treat lung cancer, a new report suggests.
There are "insufficient" specialists to serve the UK's multi-disciplinary lung cancer teams, according to the UK Lung Cancer Coalition (UKLCC).
There are only 70 specialist thoracic surgeons supporting more than 200 teams, the report found.
In addition to the shortage of surgeons, the report claims that specialist lung cancer nurses are overstretched.
"Multi-disciplinary teams (MDTs) have been at the heart of delivering improved care for many cancers," the report states.
"However, in the UK there are insufficient specialists to service effectively the large number of lung cancer MDTs, of which there are currently well over 200."
The report also found that some medics hold a "pessimistic and outdated" view of patient outcomes.
"This is compounded by patients with low expectations who may be reluctant, lack information, or be too poorly to demand better care," it said.
Health Secretary Jeremy Hunt said: "Lung cancer is the UK's biggest cancer killer. We want to make sure that our cancer services are world class and that NHS patients receive the best treatment available - if England's lung cancer survival rates were as good as the best in Europe, we could save 1,300 additional lives per year.
"Multidisciplinary teams remain the cornerstone of cancer treatment and should have the right staff to provide high quality diagnosis, treatment and care for lung cancer patients."
