How does cancer spread so quickly?

It spreads quickly

because cancer cells

never stop reproducing.• Interphase-the cell chromosomes

duplicate• Mitosis begins. • Prophase-the spindle is beginning to

form and the chromatid pairs are now visible.

• Metaphase- chromatid pairs are lined up in the center of the cell.

• Anaphase-the chromosomes have separated.

• Telophase- In the final step the cytoplasm is beginning to separate.

• Mitosis ends.
