Who Is more Prone to Cancer?

Who is more prone to cancer? How can you tell? These are questions that doctors are working hard to discover. Extensive research has revealed that some people maybe more prone to cancer than another because of their genes that where given to them by their parents. This is the reason that certain forms of cancer run in certain families. Cancer researchers are still working to figure out the exact genes that make certain people more likely to get certain types of cancer. On the other hand, a person can bring cancers, for example lung cancer, on themselves. If a person smokes all their life, they have a pretty good chance of getting lung cancer from their poor lifestyle choice. Lack of healthy diets may cause stomach or even colon cancer. Doctors are certain that there are many other factors that can lead to cancer, but they are still being researched.
