Detailed explanation-1: -Unlike healthy cells, cancer cells don’t carry on maturing or become so specialised. Cells mature so that they are able to carry out their function in the body. This process of maturing is called differentiation. In cancer, the cells often reproduce very quickly and don’t have a chance to mature.
Detailed explanation-2: -The major differences between normal cells and cancer cells relate to growth, communication, cell repair and death, “stickiness” and spread, appearance, maturation, evasion of the immune system, function and blood supply.
Detailed explanation-3: -The normal cell loses its ability to divide after certain rounds of cell division. But a cancer cell continues to divide even after endless rounds of cell division. A normal cell has the ability to contact inhibition which inhibits its division after contact with other cells.
