Lung cancer is the abnormal growth of tissue in the lungs. When cancer originates in the lungs, it can spread to other organs of the body; the spread of lung cancer to the adrenal glands, for example, may result in electrolyte disturbances....
Lung cancer arises from the cells of the lung tissue. The two primary forms of the disease, small cell and non-small cell lung cancer, differ in their appearance under the microscope and response to various cancer treatments. Medical professionals...
The National Cancer Institute describes lung cancer as cancer that originates in the tissues of the lungs, typically in the cells that line the air passages. There are two different kinds of lung cancer: small cell lung cancer and non-small cell...
Pleural mesothelioma is a rare form of cancer that attacks the membrane that surrounds the organs in the body, called the mesothelium. Each year, approximately 2,000 people in the United States are diagnosed with mesothelioma, according to medical...
Lung cancer can form within the air sacs or within the airways that carry air into the lungs. As the cancer progresses, the cancer eventually spreads throughout the lung tissue and leads to a buildup of fluid around the heart and lungs, called a...
The National Cancer Institute projects that over 155,000 people will die from lung cancer in 2010. End-of-life symptoms of lung cancer relate to the part of the body affected by the cancer. However, lung cancer may spread to the bone, liver and...
Ovarian cancer is cancer of the reproductive glands in women that produce eggs. Staging of cancer is a standardized system of describing the spread and extent of the cancer. Accurate staging is important, especially for ovarian cancer, because...
The lungs are essential to the body, as they are responsible for respiration, bringing in oxygen into the body, and expelling carbon dioxide. Lung cancer forms due to uncontrollable growth of the lung tissues that line the air passageway....
The National Cancer Institute estimates that lung cancer may cause over 157,000 deaths and lead to more than 222,000 new cancer cases in the United States in 2010. Lung cancer can originate from the air sacs of the lungs, the site of oxygen...
Shortness of breath or breathing difficulties can be frightening. They may be temporary or related to a chronic condition. Simple things, such as wearing constrictive clothing or exercise, can cause shortness of breath, but there are also very...
Lung cancer refers to a type of cancer that begins in the lungs, according to the Mayo Clinic. If you have lung cancer, you may experience a chronic cough, unexplained weight loss or wheezing. According to the Merck Manual, lung cancer is the...
Primary bone cancers are relatively rare, accounting for less than 1 percent of cancer cases, reports the National Cancer Institute. Bone cancers develop from specialized bone tissue, leading to the formation of abnormal growths on bone tissue in...
According to the Centers for Disease Control and Prevention (CDC), lung cancer kills more Americans than any other type of cancer. More than 159,000 Americans will die from lung cancer in 2009, according to the National Cancer Institute.
Many lung cancer patients develop a pleural effusion as their cancer progresses. Damage to the lung tissue leads to a buildup of fluid between the lungs and the walls of the chest cavity, causing a decrease in lung capacity. As a result, patients...
Once ovarian cancer is diagnosed, staging occurs. Staging describes the spread and extent of the cancer, and helps to determine prognosis and treatment options. Because the symptoms of ovarian cancer can be vague, approximately 80 percent of...
Ovarian cancer is an insidious cancer that often spreads to other organs before it's detected. Ovarian cancer spreads before it's detected in at least 20 percent of the cases, according to the Mayo Clinic. Ovarian cancer that spreads to the liver,...
The majority of lung cancer patients are diagnosed with non-small cell lung carcinoma. This disease grows more slowly than small cell lung cancer, but it has spread to other parts of the body by the time 40 percent of people with the disease are...
In smokers, symptoms of lung cancer may be more difficult to notice than in nonsmokers. Smokers are used to coughing, having shortness of breath at times, and being susceptible to viral or respiratory infections. Lung cancer does not usually show...
The lungs are used to breathe in vital air for respiration. When they cannot perform this duty, your whole body can suffer. Smoking is a habit that can make this job difficult and it can ultimately lead to lung cancer. Adenocarcinoma is a form of...
Asbestosis is a lung disease caused by inhaling asbestos fibers that can increase the risk of lung cancer, according to the National Heart Lung and Blood Institute. Asbestos fibers cause scarring when they enter the lung, and the scarred tissue...
Hodgkin's disease is a type of cancer involving the lymph nodes, special vessels in the body that are responsible for carrying white blood cells. Specific symptoms of Hodgkin's disease include drenching night sweats, chronic fatigue, trouble...
Lung cancer will claim a staggering 157,000 Americans in 2010, according to the National Cancer Institute. Lung cancer remains a deadly disease partly because early in the disease, it often goes undetected. Lung cancer found in a late stage...
According to a report by the Office of the Surgeon General, the single greatest avoidable cause of death and disease is smoking. One set of diseases smoking can cause are those that affect your respiratory system. Three respiratory diseases...
Once ovarian cancer has been diagnosed, it's surgically staged. In this process, a surgery called a laparotomy is done, and the staging is performed according to the size of the tumors and the spread of the cancer, according to the National Cancer...
The disease process begins when something foreign enters the body, such as a bacterial or viral substance, or when a body system, such as the circulatory, respiratory or digestive system, do not function correctly. Causes of disease include...
Ovarian cancer is the deadliest of all gynecologic cancers, according to the American Cancer Society, and the fifth most common cause of cancer deaths in women. With fewer than 20 percent of ovarian cancer cases caught before they spread past the...
Exposure to asbestos, whether by working in an asbestos industry or through accidental contact with asbestos fibers, can increase the risk of developing cancer. People who worked in an asbestos-related industry for many years are at the highest...
Your doctor may remove (biopsy) tissue samples from your abdomen or pelvis to determine the ovarian cancer stage. The staging could reveal the extent of the primary tumor (T) and whether it has spread to nearby lymph Nodes (N). In an advanced...
Lung cancer is the leading cancer cause of death among people ages 45 to 70, according to the Merck Manual. Cigarette smoke is cited as the most common contributor to lung cancer. Originating in the lung tissue, lung cancer is considered a primary...
