A normal cell turns cancerous when there is damage between a few of the genes that are in control of cell growth. These cells will eventually invade the blood supply and kill the host.
Dysplasia
If mitosis goes wrong, cancerous cells forms.
well the cells go through a interesting process that includes cell "reproduction"
Any cell in the body that mutates and loses it's normal 'lifetime' gene which controls it's time of death can be called cancerous if it becomes 'immortal'. Tumours grow at vastly different rates and there are hundreds of types of cancers.
A normal body cell transfers to the testes and become a sex cell.
yes, eg sickel celled animia
A cancerous cell.
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
Before a normal cell becomes too large, it will divide through a process called mitosis to form two identical daughter cells. This allows the cell to maintain a proper size and continue carrying out its normal activities efficiently.
Cancerous cell growth is different from normal cell growth because cancer cells divide uncontrollably and can invade surrounding tissues. Normal cell growth is tightly regulated and stops when the body doesn't need more cells. The key distinctions between the two processes are the uncontrolled division of cancer cells, their ability to spread to other parts of the body, and their resistance to signals that would normally stop cell growth.
Most cancerous tumors are detected at advanced phase of the cell cycle.
