What is the difference between a normal cell and a camcer cell

Normal cells listen to signals from neighboring cells and stop growing when they encroach on nearby tissues (something called contact inhibition.) Cancer cells ignore these cells and invade nearby tissues. Benign (non-cancerous) tumors have a fibrous capsule.

Answer: A normal cell grows and develops at a normal rate and only multiplies when it is needed to grow and thrive. Although a cancer cell has uncontrolled growth and is unsafe because then there will be too many cells multiplying and not functioning.
