Cancer cells show indefinite cellular division, lack of response to signals and other cells, resistance to apoptosis, and abnormal migration and invasiveness.
Indefinite cell division:
Cancer cells are usually mutants that lack functional forms of checkpoints for cellular division; they hastily pass though the cellular cycle over and over again. The cells usually do not fix mistakes in their DNA and therefore are genetically unstable(more mutations will continue with more divisions).
Lack of response to other cells and their signals:
Normally cells will not stop dividing when they receive signals from neighboring cells or come in physical contact with other cells. Cancer cells have lost that control and continually divide no matter what they bump into or are told to do.
Resistance to apoptosis (programed cell death):
Normal cells can be given external signals by other cells to die. Internal signals to commit suicide are given if cellular machinery is damaged beyond repair or when cellular functions are breaking down. Cancer cells continue to replicate at a fast pace, ignoring these signals to commit suicide and expanding their numbers.
Abnormally invasive / random migration:
Since genes are unstable it is likely that the proteins on the cell's surface that anchor it to the extracellular matrix and other cells will become defective or lost. The cells lose their grip and move to different spots around the body; this is especially dangerous if the cells fall into the blood stream because they can travel all over the body. These cells are also capable of living inside tissues other than where they originated.

What is characteristic of all cancers?
all the petri dishes with cancer cells have been exposed to tobacco smoke.
Do you have dormant cancer cells in your body?
One could argue that all body cells can potentially become cancerous and therefore they are all dormant cancer cells. But by that definition, a dormant cancer cell is just a normal, healthy cell.
Why is it important for the doctors to remove all the cells?
I assume you are referring to cancer treatment - It is important as any cells that are left could form a new colony of cancer cells. This would mean the cancer would return
Does cancer result from genetic mutations-?
Mutating Cells can be a source of Cancer, but not necessarily. All mutating cells do not cause Cancer.
What types of cells display protein fragments produced by the cancer within them?
all nucleated cells.

Why can't cancer cells get cancer?
Cancer cells are already cancer, it is redundant for a cancer cell to get cancer, however, it is true that cancer cells can die, for various reasons. The reason why cancer is so dangerous to the body is that cancer receives all the same support that healthy cells receive, and is not attacked by the immune system. The body takes care of its own cells; the blood supplies all the needs of cellular metabolism. That makes it easy for cells to survive. So even though cancer cells are abnormal and dysfunctional, they can usually survive because it is easy for them to do so.

What effects does cancer have on a cell cycle of a cancerous cell?
It can give cancer to all the other cells, so it causes more cells to be cancerous. It goes all around the body and the number of the cancer cells will get much more than the first.
How is cancer treated?
AnswerRife Machine kills all cancer cells except in the brain.

True or false Natural killer cells kill cancer cells?
True, NK cells are there to protect the body from any type of abnormal growth in all tissues including cancer cells.

What happens to the cells during skin cancer?
The cells die of and it takes a while for the new cells togrow back but if you live through it and the cancer is ALL the way gone then eventually the cells come back! :)
Is cancer communicable?
no, it is not communicable.because it is all about the cells and you cant exchange cells with other people so the answer is no.
What types of cells display protein fragments produced by the cancer within them?
all nucleated cells.
What is atypical cells?
Atypical cells are cells that appear to be abnormal and need further testing to determine why they are abnormal. Sometimes these cells can end up being cancer but not all atypical cells will.
