Which type of cancer shows the most aggressive growth? Explain.

- A malignant tumor is a growth of tissue that forms an abnormal mass

When studying cell division in tissue samples, scientists often calculate a mitotic index, which is the ratio of dividing cells to the total number of cells in the sample. Scientists often calculate the mitotic index to compare the growth rates of different types of tissue. Which type of tissue would have a higher mitotic index, normal tissue or cancerous tissue? Explain.

- By definition a cancerous cell is a cell that has lost it's ability to control it's growth. Cancer cells keep on growing until there is no more space. It is also possible for them to matastisize when they have greatly expanded. The reason why cancerous cells keep growing is because cancer cells have an enzyme called telomerase, which expands it's telomeres. This will provided the cell with unlimited "life"because its telomeres will never run out.
