How do cancer cells grow and replicate so quickly? Do they reproduce from themselves or somehow change normal cells to cancer cells?

Cancer cells do not proliferate more rapidly than normal cells. The big difference is that normal cells, after they have created a normal tissue, stop multiplying because of signals that they receive that the tissue construction is now complete and that further cell proliferation is inappropriate. Cancer cells, in stark contrast, continue to proliferate even when such proliferation is inappropriate. Thus, they become "deaf" to the signals around them that would normally succeed in preventing them for continuing to proliferate. Cancer cells arise from normal cells when the genes and thus the DNA within these cells, which provides information and guidelines for normal cell behavior, becomes damage -- mutated. The resulting corrupted information includes, among other damaged genes, the oncogenes described above, which function to urge the cell to proliferate relentlessly rather than in measure amounts appropriate for the construction and maintenance of normal tissue.
