i am writing a cause and effect essay on cancer (specifically lung cancer)... any help please?................

Answer 1

Cancer is caused by factors (radiation, chemicals, viruses) modifying the cells DNA to an extent where the cell starts to divide rapidly and uncontrollably (hence the tumor). I recommend reading an essay on tumor cell biology and then adapting the information for lung cancer cells.
Lung cancer specifically is most often caused by smoking (radon is a rare cause - I haven't seen a non-smoking patient whose tumor was proven to have been caused by smoking). It takes 20 years of non-smoking for the risk of lung cancer to drop to the level of non-smokers.
Asbestos doesn't cause lung cancer (it does, but in a 50 year career I have an about 50% chance of seeing such a patient) , but mesothelioma - a highly malignant tumor of the tissue covering the lung.
Hope this helped.

Answer 2

There is no such thing as an ABSOLUTELY CONCLUSIVE conclusion in science. This is particulary so when the evidence is largely epidemiological, as in the case of smoking. But keep in mind that there is no absolutely conclusive evidence that gravity causes things to fall down, either. There comes a point where the evidence for something is so overwhelming that it's almost certainly true. The evidence in the case of smoking includes studies that show that lung cancer rates track the incidence of smoking, and a laboratory studies in which animals forced to smoke or painted with tobacco tars develop cancer while control animals do not. It is *possible* that the animal studies don't apply to people and that all the people who smoke are getting cancer for some reason that doesn't have to do with smoking, but the chance is so miniscule that it isn't worth bothering with.

Answer 3

All cancers are caused by repeated assaults on natural cells. Too much sun for skin, too much smoke for lungs, too much liquor and smoke for throat, too much insulin for pancreas. Even in children, too much of something for natural cells to deal with. Lung cancer can be a result of a metastasized cancer from another area and can also be a result of direct assault to the lungs like smoking or breathing in coal dust and asbestos. We still can't say that these things CAUSE cancer, but the statistical evidence is overwhelming in certain case studies. Cancer is a general term and it means the uncontrollable growth of unwelcome cells that interfere with the normal functioning of the being.

Answer 4

From personal experience, it doesn't matter if you smoked and quit, you still are at an increased risk of having lung cancer.

My grandpa smoked for 40 yrs, quit around age 54 and at 74 was diagnosed with lung cancer. He died just under 2 months after his diagnosis. Today marks 3 years since his death.

Answer 5

One of the causes of lung cancer is smoking. And the effect is that your lungs become blackened by it. Another is family history and genetics. Some people are prone to different types of cancer more easily if it runs in the family. There are heaps of other causes and effects, you just have to research them.

Answer 6

One cause of lung cancer is rapidly growing and is giving people cause for concern and that is exposure to asbestos, My dad worked in conditions that exposed him to Asbestos and my dad passed away in May with lung cancer and the coroner recordered that asbestos was present in his lungs therefore cause of death was Industrial Disease

Answer 7

A building with asbestos can cause lung cancer as well.

Answer 8

Don't forget to include undetected radon gas in the home as a major cause.

Answer 9

Would be interested to find out more on this too

Answer 10

I'm curious as well
