natural selection would prevent that from happening.
naturally, those without cancer would have a much greater chance of surviving and reproducing. those who have cancer, or are somehow "born" with it, are much less likely to survive and carry on their genes.

Technically, we are born with all of the factors that add up to cancer. Cancer starts with 1 cell. Something in the cell goes awry, and it cannot stop dividing and making copies of itself. So this collection of cells grows and grows and many things change in the cell while this is happening. For instance, the cells become different and start to "let go" of their original surrounding tissue (which they would have never left before) and can enter the blood stream and move to other parts of the body (ie., metastasis) Scientists believe that any cell on any given day can be cancerous at any time in your life. (There is a specific number that represents DNA mutations in a given number of copies, but I don't know it off hand..) However, there are proteins that ensure that these cells do not proceed any farther than certain "checkpoints." Which basically means that our bodies already have "self defense" mechanisms to stop the mutation, and make the bad cell actually "commit suicide," (called apoptosis.) This is why cancer doesn't happen all the time.
So, the human body already has all of the items needed for cancer already. Except those cancers that are linked to some environmental factor. Whether or not you can get "cancer" from your parents is really relative. There are some situations, I am sure, where you can be born with cancer, (can't quote any literature here) in which a mutation in one of the proteins that are responsible for the self defense mechanism, I was speaking about above. However, some of those mutations could be so severe, that a fetus may never come to full term. ie., the baby can't grow and develop without this protein in its normal form.
I hope that I answered your question. It is a difficult process to understand and I am not a cancer scientist.

Cancer is not something you are born with, unless it developed during your development. The mutations that cause cancer give you an increased possibility of developing cancer, but it does not say that you will definitely get cancer. That can only be determined over time, and modulated by the environment.
On the other hand, people with particularly nasty cancer genes never make it to having kids anyway, and therefore the progression ends.

Well, there is a highly possibilities since the rapid development of the world results in the usage with various kinds of chemical substances and radioactive substances which will lead the pollution of the nature. The polluted water that we drink will cause those materials and substances to gather in our bodies subsequently leads to the mutation in the cell division and what happens is that if the cells that involved in productive system are affected, there chances of these mutated cells passed on to the next generation is very high.

Not until genes become carcinogenic. We develop cancer through cancer causing agents such as:
* Benzene (found in some sodas)
* Colbalt Sulfate (coloring agent in paints)
* Sodium Nitrate (makes meat in the store look red)
* MelQx (heterocyclic amine compounds found in meats)
* Teflon (when cooked above 500 degrees)
These are just some of the carcinogenic substances that exist in our everyday lives.

Virtually impossible. It is true that mutations are passed on your children, but cancer is due to abnormal mutations, and our cells possess the capacity to destroy more mutated cells.

Very improbable, almost impossible. Yes, mutationa are passed on. Every single person on Earth has at least one mutated cell/gene in their body, but not all are harmful/bad for you.

that is possible in the near future as now cancer are so popular and there are so many kinds and once a pregant lady is pregant then the child who is born most probably will be contacted.And the circle will keep continuing.

Yes. I have heard that we are but many of the cancers do not form in those of us resistant to it.
