Definition Of Cancer | Diagnosing Cancer

If someone asked you what cancer was, would I be able to give a definition provided in this article? The main feature of cancer is that it starts with a great group of abnormal cells that keep growing and dividing when they reach a certain size, which then invade other cells and repeat the process continues to spread to other areas of the body in a process called metastasis.

The difference between a benign cancerous tumor is a malignant tumor will continue to grow while limiting benign growth a lot of us live comfortably with them for life without even knowing it. Although it is usually a young person's disease, which can occur at any age, is responsible for thirteen percent of all deaths worldwide. Almost all cancers are caused by abnormalities in the genetic material of the transformed cells; these abnormalities may be caused by other toxic substances in the body by the snuff, radiation, chemicals or other infectious agents.

The cause may also be responsible for defective DNA replication or a genetic trait inherited from parents which means that a person can be born with them. Apparently, some people are more susceptible to it than others and may be their genetic makeup and their exposure to certain carcinogens that is responsible.

Because of the global cancer burden, it is regularly studied throughout the world and expand our knowledge on the subject. Once scientists discover the reason why some individuals are more prone to disease than others, we can be closer to creating a cure. Ultimately, even if they find a cure for some time, this research may be able to tell us how to avoid getting cancer in the first place.
