Mitosis is the division of a cell giving rise to two genetically identical daughter cells. It is seperated into five different phases which are interphase, prophase, metaphase, anaphase, and telophase. There is also the phase in which a cell spends most of its life in which is interphase. Interphase divided into three phases which are the G1 phase, S phase, and G2 phase. During the G1 phase the cell will increase in mass to prepare for cell division, there is also the little fact that the G means gap and the 1 mean first so the G1 phase is the first gap phase. The next phase in Interphase is the S phase which is the period in which the DNA synthesized, in most cells there is only a narrow window of time for DNA to be synthesized. The S in the S phase means synthesis. The third phase in Interphase is the G2 phase which is the final phase in Interphase before the beginning of prophase. In the G2 phase the cell will synthesize more proteins and will continue to grow in size, this phase is also known as the second gap phase. One of the last phases in cell divison is Cytokinesis which is the stage in which the cytoplasm of a cell will split resulting in two daughter cells.
Malignant tumors, also known as cancer are the result of uncontrolled cell division and this can occur in organ or tissue. Cells through some form of mutation lose their regulatory functions and begin to divide uncontrollably this can be caused by inheritance, certain infections, and diet and immunity weakness. The reason why it can be present in organs or tissues is because those things are made of cells and in reality tumors is just one big concentration of malfunctioning cells so that means that cancer can show up in any area of the body that is made up of cells such as tissues and organs.
