Is lung cancer passed down in families?

Is lung cancer passed down in families?

Some Types: There is growing evidence that some types of lung cancer can be genetically inherited. These are types of adenocarcinoma that are linked to genetic mutations in a protein called egfr. Often these lung cancers manifest in younger people who are never smokers. ...Read more

Cancer (Definition)

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

Is there a known genetic basis for lung cancer?

Is there a known genetic basis for lung cancer?

Genetic risk...: ...For lung cancer is a hot topic of research and there is a large national consortium studying families with multiple relatives having lung cancer to identigy genes that transmit risk. No one gene has been, or is likely to be, found, but multiple candidate "culprit" genes are under investigation. One barrier is finding families willing to participate. Look this up on cancer.Gov. ...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?

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 more

My aunt just died from lung cancer and it started in her lungs.Just wondering if its genetic and if I have any chance of getting it?

Maybe: There can be a genetic predisposition to develop malignancy. The great majority of lung cancer victims are current or former smokers. Most of the rest of lung cancer is related to radon exposure (a radioactive gas that is the product of the decay of radium) and air pollution. No matter what your genetics might be it is your responsibility to avoid known causative factors to minimize risk. ...Read more

Is lung cancer infectious, dietary, genetic or environmental?

Is lung cancer infectious, dietary, genetic or environmental?

Lung cancer: Cancer is a genetic disease, resulting from changes in the individual cell genetics. Things that cause these basic changes include some known and some unknown factors. We know that smoking tobacco is the biggest risk factor, and that radiation exposure, asbestos exposure and other environmental agents contribute. Infectious agents can cause cancers elsewhere but have only a minimal role in lung ca ...Read more

Both my uncle&my dad had lung cancer&lymphoma at the same time is this rare&could it be genetic?Many males have died from same for generations back!

Unknown: Many genetic predispositions exist that we can't identify. However, lung cancer and leukemia together is unusual and suggests an environmental exposure. Were the victims smokers? Any specific occupation (i.e. Miners or coal workers or other?) i'd be much bore suspicious that your dad and his brother were exposed to something that led to the diseases. ...Read more

Lung (Definition)

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


Genetic (Definition)

From a medical standpoint, "genetic" refers to the potential heritability of various medical conditions. While some conditions are inevitable (at some point in one's life) as a consequence of simple genetic heritability (eg huntington's disease), a large number of medical conditions (including all behaviorial health disorders) are the expressed final pathway of a ...Read more
