Lung cancer, also known as lung carcinoma, 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, which arise from mesenchymal cells. Lymphomas and melanomas can also rarely result in lung cancer.
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans.
A sarcoma is a malignant tumor, a type of cancer that arises from transformed cells of mesenchymal origin. Connective tissue is a broad term that includes bone, cartilage, fat, vascular, or hematopoietic tissues, and sarcomas can arise in any of these types of tissues. As a result, there are many subtypes of sarcoma, which are classified based on the specific tissue and type of cell from which the tumor originates. Sarcomas are primary connective tissue tumors, meaning that they arise in connective tissues. This is in contrast to secondary connective tissue tumors, which occur when a cancer from elsewhere in the body spreads to the connective tissue. The word sarcoma is derived from the Greek σάρκωμα sarkōma "fleshy excrescence or substance", itself from σάρξsarx meaning "flesh".
Pulmonology, pneumology or pneumonology is a medical specialty that deals with diseases involving the respiratory tract. It is also known as respirology, respiratory medicine, or chest medicine in some countries and areas.
Sir William Richard Shaboe Doll was a British physician who became an epidemiologist in the mid-20th century and made important contributions to that discipline. He was a pioneer in research linking smoking to health problems. With Ernst Wynder, Bradford Hill and Evarts Graham, he was credited with being the first to prove that smoking increased the risk of lung cancer and heart disease.
Roswell Park Comprehensive Cancer Center is a cancer research and treatment center located in Buffalo, New York. Founded by Roswell Park in 1898, the center was the first in the United States to specifically focus on cancer research. The center, which conducts clinical research on cancer as well as the development new drugs, provides advanced treatment for all forms of adult and pediatric cancer, and serves as a member of the National Comprehensive Cancer Network. Roswell Park Comprehensive Cancer Center is currently the only upstate New York facility to hold the National Cancer Institute designation of "comprehensive cancer center".
Lung cancer screening refers to cancer screening strategies used to identify early lung cancers before they cause symptoms, at a point where they are more likely to be curable. Lung cancer screening is critically important because of the incidence and prevalence of lung cancer. More than 235,000 new cases of lung cancer are expected in the United States in 2021 with approximately 130,000 deaths expected in 2021. In addition, at the time of diagnosis, 57% of lung cancers are discovered in advanced stages, meaning they are more widespread or aggressive cancers. Because there is a substantially higher probability of long-term survival following treatment of localized (60%) versus advanced stage (6%) lung cancer, lung cancer screening aims to diagnose the disease in the localized stage.
The "war on cancer" is the effort to find a cure for cancer by increased research to improve the understanding of cancer biology and the development of more effective cancer treatments, such as targeted drug therapies. The aim of such efforts is to eradicate cancer as a major cause of death. The signing of the National Cancer Act of 1971 by United States president Richard Nixon is generally viewed as the beginning of this effort, though it was not described as a "war" in the legislation itself.
Joseph W. Cullen was an American cancer prevention and rehabilitation researcher and briefly director of the AMC Cancer Research Center (1989-1990). He previously worked at the VA Hospital in Maryland (1968-1973), the National Institutes of Health (1973), the National Cancer Institute (NCI), and the Jonsson Comprehensive Cancer Center (1976-1982), holding high-level positions such as division director at several. He was a coordinator, creator, and researcher for the Smoking Tobacco and Cancer Program at the NCI, the largest anti-smoking campaign in the world at that time. Cullen wrote more than 90 publications in his lifetime, including four books.
Judith Longstaff Mackay, SBS, OBE, JP, FRCP (Edin), FRCP (Lon) is a British-born and Hong Kong–based medical doctor and international tobacco control advocate who has led a campaign against tobacco in Asia from 1984 onwards, campaigning for tax increases to discourage youth smoking, for the creation of smoke-free areas, and against tobacco promotion. Her main interests are tobacco in low-income countries, women and tobacco, and challenging the transnational tobacco companies.

Electromagnetic navigation bronchoscopy (ENB) is a medical procedure utilizing electromagnetic technology designed to localize and guide endoscopic tools or catheters through the bronchial pathways of the lung. Using a virtual, three-dimensional (3D) bronchial map from a recently computed tomography (CT) chest scan and disposable catheter set, physicians are able to navigate to a desired location within the lung to biopsy lesions, stage lymph nodes, insert markers to guide radiotherapy or guide brachytherapy catheters.
Cancer survival rates vary by the type of cancer, stage at diagnosis, treatment given and many other factors, including country. In general survival rates are improving, although more so for some cancers than others. Survival rate can be measured in several ways, median life expectancy having advantages over others in terms of meaning for people involved, rather than as an epidemiological measure.

Peter B. Bach is a physician and writer at Memorial Sloan-Kettering Cancer Center where he is Director of the Center for Health Policy and Outcomes. His research focuses on healthcare policy, particularly as it relates to Medicare, racial disparities in cancer care quality, and lung cancer.

Childhood cancer is cancer in a child. In the United States, an arbitrarily adopted standard of the ages used are 0–14 years inclusive, that is, up to 14 years 11.9 months of age. However, the definition of childhood cancer sometimes includes adolescents between 15 and 19 years old. Pediatric oncology is the branch of medicine concerned with the diagnosis and treatment of cancer in children.

White Americans, as the largest racial group in the United States, have historically had better health outcomes than other oppressed racial groups in America. However, in recent years, the scholarly discourse has switched from recognition of the immense positive health outcomes of white Americans towards understanding the growing persistence of negative outcomes unique to this racial group. Scholars have discussed the effects of racial prejudice and its negative effect on health outcomes to not only those being oppressed but also those being given privileges. In addition to the effects of living in a racialized society, white Americans have the highest rate of suicide and lifetime psychiatric disorders of any other ethnicity or racial category. In conjunction with these psychiatric issues, the population presents higher rates of alcohol usage alongside lower levels of psychological flourishing. Given this information, the health status of white Americans has gained increasing importance due to the differences in health outcomes between white Americans and white people from other parts of the world.
