What is Cancer?
* Cancer is many diseases, the different types correlate with the origin of the cells involved.
* The human body is made of millions of cells, grouped together to form specific tissues and organs. The blueprint for cell structure & function is DNA. Genes inside each cell order cells to grow, work, reproduce and die.
* Cancer cells are cells which have lost their original ordered life cycle and characteristics. Something environmental or internally commands the cells to grow and function differently.
* The abnormal growth of these cells eventually develop into a mass.
* Cancer cells can “metastasize” or spread to other parts of the body. They do this by direct invasion or by traveling through the lymph or blood circulation. Two classifications of cancer exist: solid tumor and hematological cancer.
