Because most cases are still found late, low-dose CT screening is the other half of the story."},{"id":"sclc","kind":"cancer","name":"Small-cell lung cancer","route":"/cancers/sclc/","tldr":"A fast-growing lung cancer. About a third of cases are confined to one side of the chest and are treated to cure with chemotherapy and radiotherapy together; the rest respond to chemotherapy and relapse quickly. After 30 years without progress, durvalumab consolidation, the T-cell engager tarlatamab and antibody-drug conjugates have each lengthened survival since 2024."},{"id":"lung-lcnec","kind":"cancer","name":"Large cell neuroendocrine carcinoma of the lung","route":"/cancers/lung-lcnec/","tldr":"Large cell neuroendocrine carcinoma is a lung cancer that looks like a large-cell tumour under the microscope but has the neuroendocrine markers and the fast, aggressive behaviour of small-cell lung cancer. It sits between the two halves of the usual split, which is why teams disagree about whether to treat it as one or the other."},{"id":"targeted-lung-health-check","kind":"term","name":"Targeted lung health check","route":"/terms/targeted-lung-health-check/","tldr":"The NHS appointment that decides whether you are offered a lung scan. People aged 55 to 74 whose GP record shows they smoke or used to are asked about their breathing, health and smoking; a risk score then decides who gets a low-dose CT scan, often in a mobile unit in a car park, every two years."},{"id":"pack-year","kind":"term","name":"Pack-year","route":"/terms/pack-year/","tldr":"The unit used to measure how much someone has smoked over a lifetime: one pack-year is twenty cigarettes a day for one year. Twenty a day for thirty years, or forty a day for fifteen, are both thirty pack-years."},{"id":"never-smoker-lung-cancer","kind":"term","name":"Lung cancer in never-smokers","route":"/terms/never-smoker-lung-cancer/","tldr":"Lung cancer in someone who has never smoked. About 15 percent of UK lung cancers and 15 to 25 percent worldwide. It is usually adenocarcinoma, commoner in women, more likely to carry a mutation a drug can target, and invisible to every screening rule, because they all start from smoking history."},{"id":"ebus-tbna","kind":"term","name":"Endobronchial ultrasound (EBUS-TBNA)","route":"/terms/ebus-tbna/","tldr":"A camera with an ultrasound probe on its tip is passed down the windpipe; the ultrasound finds the lymph nodes sitting just outside the airway wall and a needle is passed through the wall to sample them. It is how lung cancer is staged without an operation."},{"id":"tnm-9-lung-cancer","kind":"term","name":"TNM 9: what changed in lung cancer staging","route":"/terms/tnm-9-lung-cancer/","tldr":"Lung cancer has been staged by the ninth edition of TNM since 1 January 2025. The T categories are unchanged; N2 was split into N2a and N2b by how many mediastinal node stations are involved, M1c was split by how many organ systems carry metastases, and several stage groups moved as a result."},{"id":"resectability-lung-cancer","kind":"term","name":"Resectability in lung cancer","route":"/terms/resectability-lung-cancer/","tldr":"Two separate questions are hidden in the word operable. Can the tumour be removed completely with a margin, which is anatomy? And can this person survive the operation and live without the lung tissue it takes, which is physiology? A no to either makes the cancer unresectable, for different reasons and with different alternatives."},{"id":"pneumonitis","kind":"term","name":"Pneumonitis","route":"/terms/pneumonitis/","tldr":"Inflammation of the lung tissue itself, caused by a treatment rather than an infection. It shows up as a new cough, breathlessness on exertion or a fall in oxygen levels, and it is the reason a new breathlessness on immunotherapy, an antibody-drug conjugate or chest radiotherapy is treated as an emergency until proved otherwise."},{"id":"pulmonary-nodule","kind":"term","name":"Pulmonary nodule","route":"/terms/pulmonary-nodule/","tldr":"A small round shadow in the lung on a CT scan, usually under 3 cm. Most are scars or old infections, not cancer. What decides the next step is size, density and whether it grows between scans, which is why so many are simply rescanned rather than biopsied."},{"id":"lung-rads","kind":"term","name":"Lung-RADS and nodule reporting","route":"/terms/lung-rads/","tldr":"The scoring systems that turn a screening CT into an action. Each nodule gets a category from the scan, and the category dictates the next step: rescan in a year, rescan in three months, or go to a lung cancer clinic. They exist so that the same scan gets the same answer in every centre."},{"id":"radon","kind":"term","name":"Radon","route":"/terms/radon/","tldr":"A radioactive gas that seeps out of the ground into buildings, with no smell and no taste. It is the largest natural source of radiation most people meet and the second commonest cause of lung cancer after smoking. A home can be tested with a posted detector and, if the level is high, fixed."},{"id":"asbestos","kind":"term","name":"Asbestos","route":"/terms/asbestos/","tldr":"A mineral once used everywhere in building, whose fibres lodge in the lung when they are breathed in and cause cancer decades later. It causes both mesothelioma, the cancer of the lining around the lung, and lung cancer itself, and the two are different diseases with different pathways."},{"id":"smoking-cessation","kind":"term","name":"Stopping smoking","route":"/terms/smoking-cessation/","tldr":"The single largest thing anyone can do about lung cancer, before or after a diagnosis. Risk falls the longer it is since the last cigarette and falls further the younger someone stops, and the benefit is large even for people who have smoked for decades."},{"id":"haemoptysis","kind":"term","name":"Haemoptysis (coughing up blood)","route":"/terms/haemoptysis/","tldr":"Coughing up blood, or blood-streaked phlegm. It has many causes other than cancer, including chest infection, but it is the one lung symptom that sends a person aged 40 or over straight onto the suspected cancer pathway rather than to an X-ray first."},{"id":"pancoast-tumour","kind":"term","name":"Pancoast (superior sulcus) tumour","route":"/terms/pancoast-tumour/","tldr":"A lung cancer growing at the very top of the lung, where it presses on the nerves going to the arm and the nerves that control the eyelid and pupil. It usually announces itself as shoulder and arm pain rather than as a chest problem, so it is often treated as a shoulder injury first."},{"id":"spread-through-air-spaces","kind":"term","name":"Spread through air spaces (STAS)","route":"/terms/spread-through-air-spaces/","tldr":"Clusters of tumour cells found floating in the air sacs beyond the edge of the main tumour. The 2021 WHO classification recognised it as a real prognostic feature rather than an artefact of cutting the specimen, and it argues against taking out only part of a lobe."},{"id":"ttf1-p40","kind":"term","name":"TTF-1 and p40 (how lung histology is decided)","route":"/terms/ttf1-p40/","tldr":"The two stains that decide whether a poorly differentiated lung cancer is called adenocarcinoma or squamous cell carcinoma. TTF-1 positive with p40 negative means adenocarcinoma; p40 positive with TTF-1 negative means squamous. The answer decides whether the tumour is sequenced and which drugs are safe."},{"id":"mediastinal-lymph-node-stations","kind":"term","name":"Mediastinal lymph node stations","route":"/terms/mediastinal-lymph-node-stations/","tldr":"The lymph nodes in the chest are numbered by position on an agreed map, so that a scan, a needle biopsy and an operation in different hospitals all mean the same thing. Which numbered stations contain cancer decides the N category and therefore whether surgery is on the table."},{"id":"malignant-pleural-effusion","kind":"term","name":"Malignant pleural effusion","route":"/terms/malignant-pleural-effusion/","tldr":"Fluid collecting in the space between the lung and the chest wall because cancer has reached the lining. It makes people breathless, it comes back after it is drained, and the decision is not whether to drain it but how to stop it returning."},{"id":"superior-vena-cava-obstruction","kind":"term","name":"Superior vena cava obstruction","route":"/terms/superior-vena-cava-obstruction/","tldr":"A tumour or clot blocks the large vein that returns blood from the head and arms to the heart, so the face, neck and arms swell and the veins on the chest stand out. It is frightening and looks urgent, but it is usually treatable and rarely an immediate emergency."},{"id":"sublobar-resection","kind":"term","name":"Sublobar resection (segmentectomy and wedge)","route":"/terms/sublobar-resection/","tldr":"Removing part of a lobe of the lung rather than the whole lobe. For small peripheral tumours with lymph nodes shown to be clear, two randomised trials found it as good as taking the whole lobe, and it leaves more lung behind."},{"id":"roy-castle-lung-cancer-foundation","kind":"institution","name":"Roy Castle Lung Cancer Foundation","route":"/institutions/roy-castle-lung-cancer-foundation/","tldr":"The only UK

finds lung cancer early, and whose long follow-up gave the mortality signal that helped justify a national programme."},{"id":"ylst","kind":"trial","name":"YLST","route":"/trials/ylst/","status":"positive","tldr":"The Leeds trial that answered the operational questions a national screening programme actually has to answer: who responds, which risk rule to use, what it costs, and whether stopping smoking can be built into the same appointment."},{"id":"summit-lung","kind":"trial","name":"SUMMIT (lung health check study)","route":"/trials/summit-lung/","status":"positive","tldr":"The biggest single UK lung screening cohort, run across diverse and deprived London boroughs, which showed the

British trial that asked, without enthusiasm or spin, what chemotherapy is actually worth in lung cancer, and found it worth nine weeks in advanced disease and nothing at all after surgery or radiotherapy."},{"id":"violet","kind":"trial","name":"VIOLET","route":"/trials/violet/","status":"positive","tldr":"The UK trial that settled how a lung should be removed: keyhole surgery leaves people functioning better at five weeks and causes fewer serious problems after discharge, with the same survival."},{"id":"tracerx","kind":"trial","name":"TRACERx","route":"/trials/tracerx/","status":"positive","tldr":"The British study that followed lung cancers through time and space, region by

There is no screening programme aimed at survivors anywhere, although some survivor groups have a measured rate above the threshold at which lung screening was shown to save lives, so this is a gap rather than a settled answer."},{"id":"gvhd-lung-bronchiolitis-obliterans","kind":"technology","name":"The lungs after transplant: bronchiolitis obliterans syndrome","route":"/technologies/gvhd-lung-bronchiolitis-obliterans/","status":"established","tldr":"The smallest airways in the lung can scar shut after a donor transplant. It is the form of chronic GvHD that changes the outlook most, and it is usually silent until a lot of lung function has gone. It is found by breathing tests on a schedule rather than by waiting for breathlessness, so asking for spirometry is worth doing."},{"id":"egfr-mutant-nsclc","kind":"cancer","name":"EGFR-mutated non-small-cell lung cancer","route":"/cancers/egfr-mutant-nsclc/","tldr":"EGFR-mutated lung cancer is driven by a single faulty growth receptor and is treated first with a pill rather than chemotherapy. Osimertinib keeps the disease under control for about a year and a half on average, adding chemotherapy or the antibody amivantamab extends that further, and three years of osimertinib after surgery roughly halves the risk of death in early-stage disease."},{"id":"alk-positive-nsclc","kind":"cancer","name":"ALK-positive non-small-cell lung cancer","route":"/cancers/alk-positive-nsclc/","tldr":"ALK-positive lung cancer is driven by a fused ALK gene and is treated with a pill from the start.

No trial exists in the variant alone, so the parent's evidence applies: it is treated as squamous lung cancer by stage, and its high PD-L1 is why checkpoint inhibitors are used."},{"id":"lymphoepithelial-carcinoma-lung","kind":"cancer","name":"Lymphoepithelial carcinoma of the lung","route":"/cancers/lymphoepithelial-carcinoma-lung/","tldr":"Lymphoepithelial carcinoma of the lung is a rare lung cancer, seen mostly in East Asian non-smokers, in which cancer cells sit in a dense crowd of immune cells and usually carry the Epstein-Barr virus, like nasopharyngeal cancer. It is treated as a squamous lung cancer, and its high PD-L1 levels have made immunotherapy a natural choice."},{"id":"pulmonary-blastoma","kind":"cancer","name":"Pulmonary blastoma (adult)","route":"/cancers/pulmonary-blastoma/","tldr":"Pulmonary blastoma is a very rare lung cancer of adults that mixes a fetal-looking gland component with a primitive sarcoma-like component, and so belongs with the sarcomatoid lung cancers. It is different from the pleuropulmonary blastoma of young children. Surgery is the treatment; chemotherapy has no proven benefit and the outlook is poor."}]}
