What is Cancer?

Cancer is a group of abnormal, unhealthy cells.

From a biological perspective, cancer arises from a loss of normal control of cellular growth. (living cells)

 In healthy body tissues, cells grow, divided, and die. The rate of new cell growth and old cell death are kept in balance.

The cellular process is complicated and does not always work with out malfunction. The normal cell becomes abnormal.  The human body contains self-repair mechanisms that recognized damaged cells and work to destroy or control their further growth. However, sometimes defenses do not work properly.

In cancer,  the cellular balance has gone from the usual to the unexpected course.  The normal process becomes abnormal with mutated cells that have not self-destructed.  Without the death of damaged cells, the normal cells with DNA errors experience uncontrolled growth resulting in cancer.  The cancer typeis usually named based on the part of the body where it originally began.
