Cancer Cells


Cancerous cells develop when conditions for cells are favorable, therefore
allowing the divisions to continually occur, never stopping. When this happens,
a tissue mass of cells called a tumor is formed and does not respond to normal
controls regarding cell growth. Cancer cells have the following characteristics:
profound changes in the plasma and membrane cytoplasm, abnormal growth and
division weakened capacity for adhesion, and lethality. The membrane
permeability is intensified and some proteins may be altered or added. Enzyme
activities may also change and the cytoskeleton shrinks, causing a chaotic
atmosphere. Controls are lost and cell populations will dramatically increase.

New proteins cause abnormal increases in small blood vessels. Due to the high
numbers, the cells can no longer attach itself to the parent tissue. Unless the
cancerous cells are removed, they will kill the individual.
