Cancer
is a very powerful thing that takes over the lives of many people. While
researching breast cancer and how the mitosis treatments are done, I feel as if
they are getting further into finding the best cure for it. Even though cancer
can come back later on after doing the treatments, people are lucky to be free
of it for the first few months or even years. As you can see later on, mitosis
is a powerful cell that can change someone’s life in just one mistake done by
the cell.
First
off, the definitions of mitosis are“1. Sequential differentiation and segregation of
replicated chromosomes in a cell nucleus that precedes complete cell division.
2. The number of chromosomes is retained in both daughter cells” (Mifflin). These
daughter cells are made up of five stages in cancer. The five stages are these
(in order); Prophase, Prometaphase, Metaphase, Anaphase, and lastly Telophase.
Furthermore,
the five stages are semi complex. Prophase is the chromosomes condense. The
Prometaphase is when chromosomes attach
to splindles (Nuclear
envelope breaks down). Metaphase is when the chromosomes align on the
metaphase plate (cell's
midline). Anaphases are when chromosomes
separate are pulled apart into daughter
chromosomes. Lastly Telophase is finally when the chromosomes relax then
the nucleus re-forms and the cell pinches in two (cytokinesis). (IUPUI
Department of Biology).
All in all, there are various discoveries about cancer cells and treatments,
including how they work. But first you need to know that “The cancer cells
proliferate to form mass of cancer cells called a tumor. As the tumor grows
larger, it begins to release proteins from the cell to attract new blood vessel
growth (this is called "angiogenesis"). At point the tumor contains ~
1 million cells and is about the size of a 'bb'” (IUPUI Department of Biology). So two goals that they use during
the treatment is to remove the primary, or original, tumor usually by giving
surgery to the cancer patient. Then the second goal is to kill off any cancer
cells that might still be in the body (Majure).
Basically what I already knew was that they kill off the cells, good and bad, which
then leads to the patients’ hair loss, because of the cell killing. Yet I feel
as if they could find a way to only kill the specific cells that are causing
the cancer in the person. For now, though, it is fine because of the way it has
saved lives of loved ones. Also because the good cells with come back soon.
Furthermore,
(breast) cancer has a lot of processes that occur during the treatments. More
and more discoveries are happening while scientists get more into the mitosis
cells. So, as you can see, mitosis is a cell that five stages. As well as the
knowledge of the process the treatment is proceeded as.
