Why Type Of Lung Cancer Can You Get From Huffing
What is the avg age of throat or lung cancer? Can you get this at 38 or would it be at a later age?
Yes: The median age for lung ca is 72. This not the avg. It the point where 1/2 are younger and 1/2 are older. The risk of lung ca in 30's is 1.3%. The median age for laryngeal ca is 63. However the number of patients developing. Ca really spikes up at 45 yrs and older. So lung ca at 38 fairly unlikely but laryngeal ca is possible. ...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
Are "A549" lung cancer cells a particular type or sub-type of lung cancer, or is this a generic code for lung cancer cells of all types?
Research cell line: A549 cells are human lung adenocarcinoma cells.The A549 cell line was developed in 1972 through the culturing of cancerous lung tissue. They are responsible for the diffusion of substances, such as water and electrolytes, across the alveoli of lungs. In addition these cells are able to synthesize lecithin and contain high level of unsaturated fatty acids. The A549 cell line is widely used as an in vitro model for drug metabolism and as a transfection host. ...Read moreSee 2 more doctor answers
Are A549 cancer cell lines specific to the Adenocarcinoma sub-type of lung cancer, or does it mean something else?
CA cell line: The A549 cell line originated from a male patients bronchoalveolar lung carcinoma. Cell lines often acquire additional mutations that facilitates their growth in culture. They may not retain all of the characteristics of the original tumor. ...Read more
How common is lung cancer in non smokers? And is it true only a certain type of lung cancer is genetic? And if so which type?
Scientists and: Lung cancer experts are gaga about this: women, non-smoking asians have epidermal growth factor receptor defects maybe 5% of lung cancers, and alk is another molecular detected marker. At the extreme this is about 15%, more likely 5%. Wonderful science. Associated with adenocarcinoma phenotype, not squamous or small cell. It's the tobacco that's the low hanging fruit. ...Read moreSee 2 more doctor answers
Mainly in older peop: There is no specific age in lung cancer, yes it is possible at age 20, but extremely rare, it can happen even in people who never smoked.

There are multiple research projects going on to try to identify genetic/hereditary factors. ...Read moreSee 2 more doctor answers

Often asymptomatic.: This is often asymptomatic with about 5-15% detected from symptoms. Pesistent cough is the usual presenting sign, with hemoptysis, wheeze, dyspnea or difficulty breathing, depending on its site. Hoarseness, and respiratory failure can mean spread beyond the lungs. This occurs most at 55-65 years and since smoking is the most common cause, it likely takes from its start so don't start smoking. ...Read moreSee 2 more doctor answers
Yes...: Both environmental (asbestos, radon, other people's smoke, and many heavy metals and likely pollutants) and genetic ( new molecular based understanding of the epidermal growth factor receptor, path and mutations, and other molecular causes exciting researchers). ...Read moreSee 2 more doctor answers
A half pack per day: Smoker is at high risk for developing many cancers and cardiovascular and pulmonary diseases. Many write on this forum about "how long" can I do tis, or "when" will it happen. It is expensive, dumb and risky to smoke, and a half pack is a lot. Stop now, if you can, and you may find it is already not in your control; it in fact controls you and you are a slave to nicotine. ...Read moreSee 2 more doctor answers
