What Is The Pathophysiology Of Lung Cancer
Depends: Staging, location, degree of emphysema, co morbidities will determine symptoms on a particular individual. In general, most patients have no symptoms until late. Bloody sputum sometimes occurs. Some tumors may produce hormones. Weight loss may occur with advanced stage. Pneumonia, stridor, bloody pleural effusions, horner's syndrome, chest wall arm pains. Shortness of breath, recurrent pneumonias. ...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
Absolutely: Stage IA lung cancer that is resected with a lobectomy and lymph node sampling has better than an 80% cure rate. Stage IB, IIA and IIB are also frequently curable. Unfortunately 75% of lung cancers are Stage II (difficult to cure) or IV (incurable) at the time they are diagnosed ...Read moreSee 2 more doctor answers
Stage dependent: Odds of surviving lung cancer depend upon the stage (extent/spread) of the cancer at the time of diagnosis. A small tumor that is confined to the lung and has not spread to lymph nodes (stage 1) may be completely cured. An advanced tumor that is large and has spread to lymph nodes and other organs (such as brain/liver/adrenal glands) will be treated but will be challenging to completely cure. ...Read moreSee 2 more doctor answers
Risk factors: Lung cancer is most commonly a long process of years in which the lungs are exposed to damaging substances/"carcinogens". The biggest/best known is smoking.

None in early stages: Lung cancer may not produce any noticeable symptoms in the early stages. In approximately 40 percent of people diagnosed with lung cancer, the diagnosis is made after the disease has advanced. In one third of those diagnosed, the cancer has reached stage 3. Cough, weight loss, blood in sputum, hoarseness, and shortness of breath are some symptoms. ...Read moreSee 1 more doctor answer
Depends on stage...: The best predictor of surviving lung cancer is the stage or extent of the disease at diagnosis. If the cancer is small and has not spread out of the lungs, then much better odds of survival. If the cancer is large and has spread to lymph nodes and other organs (like liver, adrenals, or brain), then long term survival is less likely. ...Read moreSee 1 more doctor answer
From nothing: To terminal. Early on, no symptoms. May be identified on x-ray or ct for something independent. Cough hemoptysis- coughing blood pain in apex or chest wall shortness of breath. Progress from tiny, to small stage 1, to local spread to lymph nodes, to spread with distant metastasis stage 4. ...Read more
Many things: >80% of lung cancer is caused by smoking. However never smokers (defined as <100 cigarettes in lifetime) can get smoking. Risk factors include radon exposure, second hand smoke, and genetic mutations such as egfr activating mutations. For more info: http://bit.Ly/ygfoko. ...Read moreSee 2 more doctor answers
Multiple symptoms: Some people do not know and a small tumor is found on x ray. People with lung cancer can vary most will develop a cough possibly with blood, some will loose weight develop infections of the lung and feel weak even short of breath. At times one can have recurrent pneumonias to find a small tumor mixed into the pneumonia. THe diagnosis is made by biopsy ...Read more
Often limited: Unfortunately, early lung cancer is often asymptomatic. Symptoms may include persistent cough, bloody cough, pain, short of breath. The following link may assist you in the possible symptoms: http://goo.Gl/vvhhy there is screening for appropriate candidates to help find it early. ...Read moreSee 1 more doctor answer
Depends on stage: Lower stage non-small cell lung cancer (nsclc) has better survival based on stage appropriate therapy than later stage tumors. The standard of care therapy for stage i and ii nsclc is surgery. For stage iiia chemoradiation followed by surgery or chemoradiation alone and stage iiib and IV chemotherapy +/- radiation. ...Read moreSee 1 more doctor answer
Several: Possible treatments for lung cancer include surgery, radiation therapy, radiofrequency ablation, conventional chemotherapy, targeted molecular biological therapies, and others. The main determinants of the "best" therapy for a given patient are the stage (extent) of the cancer and the patients underlying health and lung function status. Smoking cessation is very important. Hope that this helps. ...Read more
Multiple: There are multiple types of lung cancers based on cells that cancer originates from. Two broad categories are small cell which tends to be more systemic, and non-small cell that tends to be more localized in the lung to start. There are different variants within these categories. Also many lung lesions are actually from cancers elsewhere in body. Metastatic disease. ...Read more
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
