What is the Most Important Property of a Cancer Cell

Question

What is the most important property of a cancer cell, whether it is in the body or in vitro?
A)its chromosome complement
B)its loss of growth control
C)its size
D)its secretions
E)its inability to divide

Accepted Answer

The most important property of a cancer cell is its loss of growth control, which leads to uncontrolled cell division and proliferation. This is what allows cancer cells to grow and form tumors, and ultimately metastasize to other parts of the body. The other options listed (chromosome complement, size, secretions, inability to divide) may be important characteristics of cancer cells, but they are not as essential as the loss of growth control.
