How do cancer cells differ from health cells?
A
Cancer cells grow uncontrollably, forming tumors
B
Cancer cells grow slowly, forming tumors
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -For instance, cancer cells: grow in the absence of signals telling them to grow. Normal cells only grow when they receive such signals. ignore signals that normally tell cells to stop dividing or to die (a process known as programmed cell death, or apoptosis).

Detailed explanation-2: -Unlike healthy cells, cancer cells don’t carry on maturing or become so specialised. Cells mature so that they are able to carry out their function in the body. This process of maturing is called differentiation. In cancer, the cells often reproduce very quickly and don’t have a chance to mature.

Detailed explanation-3: -Uncontrolled Cell Growth: Cancer Because cancer cells don’t respond appropriately, they grow uncontrollably and can eventually damage the tissues around them. If cancer cells continue to grow, they will eventually form a mass called a tumor.

Detailed explanation-4: -Cancer cells have gene mutations that turn the cell from a normal cell into a cancer cell. These gene mutations may be inherited, develop over time as we get older and genes wear out, or develop if we are around something that damages our genes, like cigarette smoke, alcohol or ultraviolet (UV) radiation from the sun.
