What is one main difference between a normal cell and a cancer cell

Explanation:

Cancer cells look different from normal cells under a microscope. Normal cells have a large amount of cytoplasm, a single nucleus and nucleolus and fine chromatin. In contrast, cancer cells have a small amount of cytoplasm.

Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive. One important difference is that cancer cells are less specialized than normal cells. That is, whereas normal cells mature into very distinct cell types with specific functions, cancer cells do not.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.
