What are cancer cells?

Cancer describes any group of diseases that are characterized by uncontrolled cell growth that are destructive to tissues and organs in the body, and can lead to death. Cancer cells are formed when normal cells are damaged and then multiply. It is not uncommon for the cell to form abnormally or become damage, but in most cases the cell is simply self -destructive in a process called apoptosis. The immune system of the body appears to be normal cells of the body and therefore the defense of the body does not attack them.

Most cancer cells multiply and remain located, at least initially, creating a tumor, one of the remarkable exceptions is leukemia. However, not all tumors are cancer. Benign tumors are growth that can share certain properties with cancer tumors, but are self-reverse and non-destructive. Usually they do not return after removal.

Malignant or cancerous tumors form due to mutation or other damage to the genetic material ununormal cell. This occurrence in itself is the timeThat in the body, but almost always stopped when the damaged cell killed itself, which prevents the spread of mutation. Strategic cell death or apoptosis is essential for the growth and survival of all living things. This fact is particularly reflected when apoptosis does not occur. The mutated cell survives to duplicate, and then these two cells are divided and more.

There may be other mutations and the replication continues uncontrollable until the tumor is formed. The normal process of cell division is not like the growth of cancer cells, which is unlimited by apoptosis. These cancer cells are not somehow recognized as harmful natural defense systems of the body and can continue to multiply. If it is not removed, this group of cells may begin to destroy the tissue in which they have been formed and attack other areas of the body.

The

Canco Setting ER usually focuses on the removal and destruction of the cancer cells. They can move from the surgeryGical procedure after removal of tumors, drugs that try to stew the blood supply to the tumor to radiation therapy. Surgery is usually a preferred method of removing localized tumors, and it is also necessary to remove the small edge of healthy tissue, because even one microscopic cancer cell can grow into the tumor. The reasons why mutated cells become cancer is little known, but there are a large number of research to prevent and more effectively treat all types of cancer.
