Is Lung Cancer Contagious
My father has been diagnosed with prostate/stomach/lung cancer that is widespread. Is this contagious to my young children or type 1 diabetics?
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
I had lung cancer and only have right lung. On a recheck 5 yrs later there’s an opaque fissure in my right lung what does that mean?
Typo: I bet it is an error and "oblique fissure" is meant. ...Read more
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 more
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 more
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 more
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 more
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 more
Early on, no symptoms. May be identified on x-ray or ct for something independent.
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
It depends: On the extent, location, and type of lung cancer. There may be no symptoms with a small tumor. With more extensive involvement, there may be constitutional symptoms such as weight loss. There are numerous non metastatic potential disorders (paraneoplastic syndromes). There may be cough, chest pain, or hemoptysis depending on the local extent. ...Read more
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
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 more
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 more
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
Imaging and biopsy: Most lung cancers are discovered by imaging studies such as chest x-rays or ct scans. These will show mass lesions that should not normally be present. If such a lesion is detected, then it is usually sampled by needle aspiration or bronchoscopy, and cells or pieces of tissue are studied in a laboratory under a microscope to decide if a malignancy is present and to decide what type the tumor is. ...Read more
"from 2006-2010, the median age at death for cancer of the lung and bronchus was 72 years of age. Approximately 0.0% died under age 20; 0.1% between 20 and 34; 1.1% between 35 and 44; 7.8% between 45 and 54; 19.6% between 55 and 64; 30.5% between 65 and 74; 30.1% between 75 and 84; and 10.8% 85+ years of age"

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
