Lung cancer is a disease in which uncontrolled abnormal cell growth begins in the lungs. This eMedTV article offers an overview of lung cancer, including information about causes, types, and symptoms of the disease.
As explained in this eMedTV resource, there are two basic types of lung cancer: non-small cell lung cancer and small cell lung cancer. Within these two groups are more specific forms of lung cancer, such as squamous cell carcinoma.
Non-small cell lung cancer is the more common of the two general types of lung cancer. This section of the eMedTV library discusses the specific types of non-small cell lung cancer and provides information about tests used to diagnose the disease.
Small cell lung cancer is a general type of lung cancer that grows and spreads quickly. This eMedTV article defines the three types of small cell lung cancer, lists symptoms of the disease, and explains how it is diagnosed and treated.
The most common causes of lung cancer are linked to tobacco smoke, pollution, and lung diseases. This part of the eMedTV archives describes various causes of lung cancer and offers information on the latest research on cancer causes.
As explained in this eMedTV article, early symptoms of lung cancer do not always develop. In fact, about a quarter of the people with the disease exhibit no early symptoms of lung cancer -- including some people with advanced cases of lung cancer.
Loss of appetite, fatigue, and a cough that doesn't go away are some of the symptoms of lung cancer. This eMedTV resource takes a look at lung cancer symptoms and explains how not everyone with the disease will have symptoms at the time of diagnosis.
To make a lung cancer diagnosis, the doctor will ask questions, conduct a physical exam, and order certain tests. This eMedTV Web page describes tests and procedures, such as sputum cytology, that may be used to reach a lung cancer diagnosis.
Lung cancer staging is conducted to find out whether the cancer has spread, and if so, to what parts of the body. This eMedTV article explains tests used in lung cancer staging (such as CT scan and MRI) and links to additional information.
The different stages of lung cancer are used to measure if a cancer has spread, and if so, how far. This eMedTV article takes an in-depth look at small and non-small lung cancer stages, and includes detailed definitions.
Types of treatment for lung cancer can include surgery, chemotherapy, photodynamic therapy, and radiation therapy. This eMedTV segment discusses various aspects of lung cancer treatment, including second opinions, side effects, and nutrition.
A lung cancer prognosis is an informed medical opinion about the outcome of the disease in a patient. This eMedTV resource explains the factors (such as the stage and type of lung cancer) that affect a patient's prognosis.
Lung cancer screening is used to detect cancer before symptoms develop. This eMedTV Web page explains the benefits and risks associated with lung cancer screening, which is normally done with chest x-rays or a procedure known as sputum cytology.
Preventing lung cancer involves eliminating or reducing the risk factors for the disease, such as cigarette smoking. This eMedTV resource discusses lung cancer prevention strategies and offers information about quitting smoking.
As this eMedTV article explains, lung cancer and Hodgkin's disease are often linked. Data on lung cancer and Hodgkin's disease indicate that people with Hodgkin's who receive chemotherapy or radiotherapy are at high risk of developing lung cancer.
New research shows that a lung cancer gene is a potential cause of lung cancer. This eMedTV article further explores the lung cancer gene and provides an explanation of this inherited component for lung cancer.
As explained in this eMedTV segment, lung cancer research is being conducted to assess the effectiveness of using biological therapy to treat the disease. This article also discusses other research being done to improve how the disease is treated.
Lung cancer statistics indicate that, in 2002, 90,121 men and 67,509 women died from the disease in the US. This eMedTV resource provides lung cancer statistics on death rates, race and ethnicity, and comparisons to other leading causes of death.
