1. Lung cancer

   Lung cancer, also known as lung carcinoma (since about 98–99% of all lung cancers are carcinomas), is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. Lung carcinomas derive from transformed, malignant cells that originate as epithelial cells, or from tissues composed of epithelial cells. Other lung cancers, such as the rare sarcomas of the lung, are generated by the malignant transformation of connective tissues (i.e. fat, muscle, bone), which arise from mesenchymal cells. Lymphomas and melanomas (from lymphoid and melanocyte cell lineages) can also rarely result in lung cancer. In time, this uncontrolled growth can metastasize (spreading beyond the lung) either by direct extension, by entering the lymphatic circulation, or via hematogenous, bloodborne spread – into nearby tissue or other, more distant parts of the body. Most cancers that originate from within the lungs, known as primary lung cancers, are carcinomas. The two main types are small-cell lung carcinoma (SCLC) and non-small-cell lung carcinoma (NSCLC). The most common symptoms are coughing (including coughing up blood), weight loss, shortness of breath, and chest pains. The vast majority (85%) of cases of lung cancer are due to long-term tobacco smoking. About 10–15% of cases occur in people who have never smoked. These cases are often caused by a combination of genetic factors and exposure to radon gas, asbestos, second-hand smoke, or other forms of air pollution. Lung cancer may be seen on chest radiographs and computed tomography (CT) scans. The diagnosis is confirmed by biopsy, which is usually performed by bronchoscopy or CT-guidance.The major method of prevention is the avoidance of risk factors, including smoking and air pollution. Treatment and long-term outcomes depend on the type of cancer, the stage (degree of spread), and the person's overall health. Most cases are not curable. Common treatments include surgery, chemotherapy, and radiotherapy. NSCLC is sometimes treated with surgery, whereas SCLC usually responds better to chemotherapy and radiotherapy.Worldwide in 2020, lung cancer occurred in 2.2 million people and resulted in 1.8 million deaths. It is the most common cause of cancer-related death in both men and women. The average age at diagnosis is 71 years. In most countries the five-year survival rate is around 10 to 20%, although outcomes typically are worse in the developing world.

1. lung cancer

   Lung cancer is a type of malignant disease characterized by the uncontrolled growth of abnormal cells in one or both lungs, particularly in the cells that line the air passages. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, the abnormal cells can form tumors, impair lung function, and spread to other parts of the body. The two main types of lung cancer are small cell lung cancer and non-small cell lung cancer, which are determined by the size of the cells when viewed under a microscope. Factors like smoking, exposure to radon or asbestos, and a family history of lung cancer can increase the risk of developing this disease.

1. Lung cancer

   Lung cancer is a disease characterized by uncontrolled cell growth in tissues of the lung. If left untreated, this growth can spread beyond the lung in a process called metastasis into nearby tissue or other parts of the body. Most cancers that start in lung, known as primary lung cancers, are carcinomas that derive from epithelial cells. The main types of lung cancer are small-cell lung carcinoma, also called oat cell cancer, and non-small-cell lung carcinoma. The most common symptoms are coughing, weight loss and shortness of breath. The most common cause of lung cancer is long-term exposure to tobacco smoke, which causes 80–90% of lung cancers. Nonsmokers account for 10–15% of lung cancer cases, and these cases are often attributed to a combination of genetic factors, radon gas, asbestos, and air pollution including second-hand smoke. Lung cancer may be seen on chest radiograph and computed tomography. The diagnosis is confirmed with a biopsy which is usually performed by bronchoscopy or CT-guidance. Treatment and long-term outcomes depend on the type of cancer, the stage, and the person's overall health, measured by performance status.

Examples of lung cancer in a Sentence

1. David Hammond:

   Viewing an image of the effects of lung cancer or heart disease communicates the severity of smoking-related disease far more effectively than words alone.

2. Robert Rintoul:

   If you have a lung cancer inside your lung, that cancer is producing a range of chemicals in very, very minute amounts. And this device can collect those samples, those tiny amounts of volatile organic compounds, which we can then analyze in the laboratory. And in effect, it's a bit like a fingerprint. If you have a lung cancer we believe that we can detect these samples and that fingerprint will tell us whether the person has lung cancer or not.

3. Fouad Namouni:

   This marks the end of the chemotherapy era in second-line treatment of lung cancer.

4. Jonathan Parsons:

   It’s pretty rare to have an isolated cough as the only symptom to herald a lung cancer, if you really did have lung cancer, it’s unlikely that you are going to be coughing with no other symptoms for more than 8 weeks—you’re going to develop other things.

5. Otis Brawley:

   It's not whether you have pancreatic cancer, or colon cancer or lung cancer that's going to be important to the treating clinician, what's going to be important to the treating clinician is what's wrong with your tumor at a molecular level.
