Answer 1

Answer:

Explanation:

The key difference between cancer cells and normal cells is that the cancer cells divide uncontrollably while normal cells divide in an orderly manner. Normal cells divide in an orderly way to produce more cells only when the body needs them.

A tumor is an abnormal lump or growth of cells. When the cells in the tumor are normal, it is benign. Something just went wrong, and they overgrew and produced a lump. When the cells are abnormal and can grow uncontrollably, they are cancerous cells, and the tumor is malignant.
