cancer cells and how they differ from normal cells;genes associated with cancer?

Answer 1

Cancer cells differ from normal cells in that they are rogue cells which are no longer growing in response to normal signals but just grow and grow, spreading and taking over tissue. They start taking over body resources and impede function.There are many genes which control different cells so too many to mention.

Answer 2

Cancer cells tend to be normal cells that did not die when they were suppose to. We call the death of cells - apotosis.

There are genetic propensities toward certain kinds of overgrowth of cells that produce a cancer tumor. However, there are times we see people who have done everything right, and still get cancer.

Therefore, it is not possible to draw any tight conclusions that doing certain things "will" cause cancer. The closest cancer to lifestyle is colon cancer, because we use a lot of high fat, low residue diets. There are some interesting chains of events that may lead to colon cancer.

And then, there is a new suspect in the research world, and that is a lack of vitamin D that naturally comes from the sun. Keep your eyes and ears open for more details

Hope this helps.

Answer 3

Scientists spotted more than 1,000 gene mutations in the cancers' DNA.
Cancer cells mostly divide by meiosis

Answer 4

the theory is that we all have cancer cells and it is controlled by a suppressor gene. so when they are not cancer cells, they are our normal cells. when a trigger (a carcinogen) deactivates the suppressor gene, the normal cells start dividing uncontrollably
