Question

Quizplus · Accepted Answer

Abnormal, undifferentiated tumor cells are often produced by a process called anaplasia, which is the loss of structural and functional differentiation of normal cells. Hyperplasia refers to an increase in the number of cells in an organ or tissue, metastasis is the spread of cancer from one part of the body to another, and edema is the accumulation of excess fluid in the tissue. None of these processes directly produce undifferentiated tumor cells.
