Cancer cells can start in any part of the body, but some sites are more favored. Unfortunately these cells rarely remain where they originate. Clusters or clumps of cancer cells break off and travel in the blood stream to other parts of the body – from the breast to the armpits, for example. This spread of cancer cells is called metastasis.
Cancer cells are definitely different from ordinary cells, and these differences can be observed in tiny sections of tissue examined under a microscope. Identifying cancer cells is an important part of the job of the pathologist.

The main difference between normal and cancer is one of the growth and differentiation: most cancer cells are in their structure more like those of the young organism (fetus) than those of the adult.
They generally grow and divide more rapidly and in a disorganized fashion, but normal cells only divide and grow until they come into contact with adjacent cells and then stop their growth.
Researchers have tried to treat cancers by using drugs which inhibit the division of cells. The most rapidly dividing cancer cells will be affected by these drugs before the more slowly growing normal cells.
The major problem in cancer research now is concentrated on trying to find out the more delicate difference between cancer and normal cells.

Many names have been given to the different cancer cells identified. Most end in the suffix «oma». Thus, for example, carcinoma is cancer of the epithelial tissues (skin, glands, membranes); sarcoma, of connective tissue (bone, muscle); melanoma, of the pigment cells of skin. Leukemia, so-called cancer of the blood, reflects a disturbance in the blood-forming organs, which manufacture so many white blood cells that the essential red blood cells are crowded out.
