Cancer is the result of an improperly regulated cell cycle. describe two reasons why cells can form tumors.

•Continuous cell division

•Too little cell division

Explanation:

Cancer is an abnormal growth in the body that occurs when cell growth is continuous, not stopping and unchecked.

Factors that affects cell division includes

•Nutrients

•Genetics.

•Chemical and toxics,

•Stress.

Process of cell division is controller by mitosis and cytokinesis.

When cell division is too little it can also lead to abnormal cell growth called cancer. this is because inhibitors of the cell cycle helps to control cell division, when the activity of this inhibitors are also small, it could lead to cancer.

Too activated or less active cell division results to cancer.
