In human body, the cell growth and differentiation are highly controlled and regulated, but in cancer cells

there is breakdown of these regulatory mechanisms leading to formation of benign and malignant tumors

controlled cell division and overproduction of genetic material occur

RNA is mutated and produced in less amount

DNA is mutated and produced in less amount

Explanation:

In cancer cells, there is breakdown of these regulatory mechanisms. Normal cells show a property called contact inhibition by virtue of which contact with other cells inhibits their uncontrolled growth. Cancer cells appears to have lost this property. As a result of this, cancerous cells just continue to divide giving rise to masses of cells called tumors. Tumors are of two types: benign and malignant.
