What Is The Difference Between Lung Cancer And Lung Disease
Different things: Emphysema is destruction of lung tissue from (most often) smoking. Lung cancer is an abnormal growth of lung tissue that can cause destruction of many tissues, not just lung. They are completely different diseases. But, because the most common cause of lung cancer is smoking, many times patients with lung cancer have emphysema and vice versa. ...Read moreSee 1 more doctor answer
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Different: Non small cell lung cancer mainstay of therapy is surgical resection for appropiate lesions. 5yr survival for stage i nsclc after surgical resection is about 70%, stage ii about 30%. Chronic lung disease is emphysema, bronchitis, asthma, obviously a totally different diagnosis. Patients may develop lung cancer with or without chronic lung disease but more common in smokers. ...Read moreSee 1 more doctor answer
COPD versus cancer: In emphysema the air sacs of the lung (alveoli) are damaged. The result is the lung "traps air in the damaged sacs and it becomes hard to exhale. The lung becomes over inflated. Breathing (getting oxygen in and carbon dioxide out) are progressively harder. In lung cancer a cell is damaged and can not regulate its growth, ( ie becomes cancerous) with tumor formation. Both are linked to smoking. ...Read moreSee 1 more doctor answer
Cause and Effect: Lung disease can be caused by many factors like cigarette smoking, tuberculosis, lung cancer, asthma, and others. Lung injury could occur from lung disease, trauma to the chest wall/lungs, or inhalation of toxic substance. So, a lung injury can happen from an isolated sudden accident or it could happen as a result of a disease process. I hope this helps. ...Read more
Different cell types: lsmall cell cancer of the ung is a neuroendocrine tumor responding to chemo such as the adriamycins (doxorubicin). Non small cell cancer represents the adenocarcinomas and squamous cell cancers requiring a different groujp of drugs that usually include the platinums and the newer monoclonal antibodies. ...Read more
Location, Incidence: Colon cancer arises from a site involving the large intestine commonly called the colon (ascending, transverse, descending, sigmoid). Intestinal cancer usually refers to small intestinal cancer that arises from the duodenum, jejunum or ileum. Colon cancer is much more common compared to cancer arising from the small intestines which is considered rare. ...Read moreSee 1 more doctor answer
HERE IT IS: 1st: nothing such as thoracic or chest cancer. Both are anatomical descriptions of the area above the diaphgram. There are many cancers that can occur in this area ei: esophageal, lung, lymphoma and thymoma to name a few. So the only correlation is that lung cancer occurs and is found in the thoracic/chest area. ...Read moreSee 1 more doctor answer
Be careful: If you hear this, you are probably talking to a charlatan, perhaps a peroxide advocate. Cancers develop a relatively anaerobic internal milieu by natural selection over time and this accounts for some of the real science that these folks use in support of their claims. ...Read more
Breast & Lung Cancer: Breast Cancer and Lung Cancer arise from different parts of the body. Breast cancer almost always arises from the ducts of the breast. Lung cancer usually arises from the lining of the lung. The two cancer have different natural histories. Breast cancer may metastasize or spread to other part of the body, including the lungs ...Read more
A lot: Stage refers to extent of cancer: generally stage 1 & 2 are early cancers; stage 3 involves spread to the nodes or structures in the middle of the chest; stage 4 involves spread to both lungs or other organs. Grade refers to the degree of abnormal appearance of the cancer when seen under the microscope- usually grades range from 1-3. ...Read moreSee 2 more doctor answers
Entirely different: Different types of cancer. Small cell multiplies fast and is considered spread at the time of diagnosis. Because of that, it may also respond better to chemotherapy. Non-small-cell grows more slowly and if found in an early stage, may be curative by surgery. ...Read moreSee 1 more doctor answer
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
