why do cancer cell replicate too fast? do they replicate same as normal cells?

Answer 1

Cancer is characterized by proliferation of abnormal cells which multiply out of control, destroying healthy tissue and endangering life. This unchecked "cancerous" growth spreads throughout the body, interfering with the ability of cells, organs, and other structures to perform their normal functions.

Cancer begins when a cell reproduces for no obvious reason and is not receptive to the normal signal to stop reproducing. These abnormal cancer cells multiply out of control and this unchecked growth spreads through the body, interfering with the ability of cells, organs, and other structures to perform their normal functions.

There are many forms of cancer that affect the human body. Sarcoma cancers affect the blood vessels, bone, fat, muscle and other connective tissues. Carcinoma cancers affect the tissue that covers internal organs. Leukemia cancer grows in blood-forming tissue. Lymphoma cancer starts in the cells of the immune system and then can spread to other parts of the body.-

Answer 2

I believe that cancer cells duplicate just as fast as normal cells, but they don't know when to stop. It leads to crowdedness, causing cells to die.

It's like death from too much life.
