Lung cancer is a disease of uncontrolled cell growth in tissues of the lung. This growth may lead to metastasis, which is the invasion of adjacent tissue and infiltration beyond the lungs. The vast majority of primary lung cancers are carcinomas of the lung, derived from epithelial cells. Lung cancer, the most common cause of cancer-related death in men and women, is responsible for 1.3 million deaths worldwide annually, as of 2004.[1] The most common symptoms are shortness of breath, coughing (including coughing up blood), and weight loss.[2]

The main types of lung cancer are small cell lung carcinoma and non-small cell lung carcinoma. This distinction is important, because the treatment varies; non-small cell lung carcinoma (NSCLC) is sometimes treated with surgery, while small cell lung carcinoma (SCLC) usually responds better to chemotherapy and radiation.[3] The most common cause of lung cancer is long-term exposure to tobacco smoke.[4] The occurrence of lung cancer in nonsmokers, who account for as many as 15% of cases,[5] is often attributed to a combination of genetic factors,[6][7] radon gas,[8] asbestos,[9] and air pollution[10][11][12] including secondhand smoke.[13][14]

Lung cancer may be seen on chest radiograph and computed tomography (CT scan). The diagnosis is confirmed with a biopsy. This is usually performed by bronchoscopy or CT-guided biopsy. Treatment and prognosis depend upon the histological type of cancer, the stage (degree of spread), and the patient's performance status. Possible treatments include surgery, chemotherapy, and radiotherapy. Depending on the stage and treatment, the five-year survival rate is 14%.[2]

About diseases

A disease is an abnormal condition affecting the body of an organism. It is often construed to be a medical condition associated with specific symptoms and signs.[1][2][3] It may be caused by external factors, such as infectious disease, or it may be caused by internal disfunctions, such as autoimmune diseases. Ecologically, disease is defined as maladjustment of a body with environment.

In humans, "disease" is often used more broadly to refer to any condition that causes pain, dysfunction, distress, social problems, and/or death to the person afflicted, or similar problems for those in contact with the person. In this broader sense, it sometimes includes injuries, disabilities, disorders, syndromes, infections. Isolated symptoms, deviant behaviors, and atypical variations of structure and function, while in other contexts and for other purposes these may be considered distinguishable categories. A diseased body is quite often not only because of some dysfunction of a particular organ but can also be because of a state of mind of the affected person who is not at ease with a particular state of its body.

Death due to disease is called death by natural causes. There are four main types of disease: pathogenic disease, deficiency disease, hereditary disease, and physiological disease.

Aspartame (or APM) (pronounced /ˈæspərteɪm/ or /əˈspɑrteɪm/) is an artificial, non-saccharide sweetener used as a sugar substitute in some foods and beverages. In the European Union, it is codified as E951. Aspartame is a methyl ester of the aspartic acid/phenylalanine dipeptide. It was first synthesized in 1965.

The safety of aspartame has been the subject of several political and medical controversies, Congressional hearings and internet hoaxes since its initial approval for use in food products by the U.S. Food and Drug Administration (FDA) in 1974. A 2007 medical review on the subject concluded that "the weight of existing scientific evidence indicates that aspartame is safe at current levels of consumption as a non-nutritive sweetener".[3] However, because its breakdown products include phenylalanine, aspartame must be avoided by people with the genetic condition phenylketonuria (PKU).
