Why cancer cells are difficult to destroy?

Answer 1

When your body's cells replicate, they go through 3 phases. The first being the growth phase. The second being synthesis or replication of the DNA. The third being the phase where it checks over the replicated DNA to check for any errors (or spell check kind of). Cancer is when those body cells that are being replicated, are replicating way too fast for them to go through the 3rd phase and get checked for errors. Usually, when they are replicating this fast, there is some sort of mutation that is causing them to replicate this quickly.

When these cells skip the spell check, they have a mutation and this mutation causes the mutated DNA to take over all of the normal DNA. If the cancer is caught early enough, then there are technologies that can get rid of the small amount of mutated DNA but if noticed too late, the cancer cells have already taken over that persons body, and it would take some extensive treatment to even attempt to get rid of all the cancer cells..

Hopefully this helped answer your question. :)

Answer 2

Good question. Metastatic cancer means that the cancer has moved from it's primary organ to other organs. All it takes is one cancer cell to produce millions and millions of other cancer cells.

Metastatic cancer is difficult to treat because once it enters they blood stream or lymph system, it is like trying to find a "needle in a haystack"

Remember, in order to get rid of cancer, EVERY cancer cell must be removed. Once it has spread, it is very difficult to locate and get rid of them all.

Answer 3

Great question.

Cancer is difficult for the body to fight because cancer is your own cells misbehaving.

Cancer is the unregulated growth of cells. Normal cells receive signals to replicate and go through check points to ensure that everything is normal and healthy. Cancer cells typically replicate very quickly without the checkpoints. This leads to an accumulated mass of cells which is called a tumor.

Our immune systems are programed to find foreign matter, not their own cells. Since Cancer is the bodies own cells the immune system doesn't recognize it as foreign. Many types of cancer cells have also been found to secrete immunosuppressing molecules.

Answer 4

it is difficult because cancer is your own cells, and they have just malformed. they also have to destroy thousands of cells, without injuring you to the point that you cant recover, so it is hard to make sure that they did get all of the cells, so the cancer doesn't come back

Answer 5

because the disease always finds a way to evolve and get around the "cures" they come up with.

Answer 6

Because is starts out simply as a rogue-cell, and any treatment struggles to identify between it and another normal cell!

Answer 7

No, not if it isn't let go. In the first stages it can be removed by getting it cut out in the area where it is found. Not much fun, but it works.
