Question 1

if a cancer cell from outside gets into you and that cell has no mhc on it then how will the persons body recognise that its foreign and should be killed ?

Accepted Answer

: There has been no instance of cancer spread in the fashion you conjure up.
You can reduce your risk of cancer by adopting healthy habits: Eat a mostly vegetarian diet, avoid alcohol, tobacco and street drugs, avoid excessive exposure  to sun, get HPV vaccine, exercise 30 minutes each day, drink enough water so your urine is mostly colorless.

Question 2

how can cancer cells take over?

Accepted Answer

Cancer cells: Have lost most if not all of the control mechanisms normal cells have, so they grow uncontrollably and spread to other organs, ultimately causing irreversible damage to vital systems and death. It is more complex than that, of course, but we have a limited space to answer.

Question 3

what converts normal to cancer cells?

Accepted Answer

Multiple steps: Changes in the dna of cells, some changes may be inherited, increase the growth rate of cells and additional changes to the 'dna develop and select for more growth.  Many incipient cancers probably die out in the process.  As more dna changes promoting growth accumulate the abnormal cells become autonomous, invade and metastasize.  On average a cancer has 90 dna changes/mutations.

Question 4

what can you tell me about cancer cells?

Accepted Answer

One mutant cell: One normal cell inside your body mutates (becomes abnormal), and begins to divide.  The normal "stop" signal that tell a cell to stop dividing doesn't work, so the cells keep dividing.  One cell becomes two, two become four, four become eight, etc.  It takes millions of cancer cells to form a tumor that can be seen on an X-ray or felt on exam.

Question 5

how do you find the different cancer cells?

Accepted Answer

Under the Microscope: Cancer is usually diagnosed by performing a biopsy of the area of suspicion. The tissue is examined by a pathologist for microscopic evaluation, supplemented by special tests to look for proteins associated with certain cancers.

Question 6

can cancer cells continue living after you die?

Accepted Answer

No: They die with the person -- perhaps even a bit faster as they're generally less adaptable.

Question 7

how to know when do cancer cells begin growing?

Accepted Answer

That is a vague ques: Cancer cells are rarely quiet...They are nearly always growing although there is a theory of dormancy which is talked about but it is hard to prove it!

Question 8

please help! what happens in cancer cell biology?

Accepted Answer

Man, there are : ..Entire books meant to answer that.  Cells have instructions in their dna that establish their behavior.  Sometimes those instructions are changed (mutations) and the cells start dividing too much, "learn" how to spread, and bypass their "self destruct" mechanisms. That ultimately leads to a malignancy. It is way more complicated that that but i ain't got space.  Try the acs or the nci websites.

Question 9

are all cancer cells the same regardless of organ?

Accepted Answer

No: Cancer is a general term. Cancers vary depending on the cell of origin.

Question 10

what are the ways that cancer cells begin to grow?

Accepted Answer

Sequential mutations: series of gene changes usually beginning with p53 giving immortality to the cell.  Then genes  induce oncofetal proteins which function to allow fetus to mature and then turn off.  Post translational modifications in the proteins of these genes which have been demethylated by virus or carcinogen lead to cells producing the cancer protein and then phenotypically change to the malignancy.
