Question
CANCER-MITOSIS GONE WRONG!!! . What is Cancer? o Cancer is the uncontrolled growth and division of cells. Cells wil keep growing and dividing, even if your body does not necessarily need them. This means that there is a malfunction in the body in knowing when to start and stop mitosis. The cell usually spends most of its time in interphase and spends a very small amount of time in actual cell dividing phases. However, cancer cells are in a rapid state of cell division and spend much more time out of interphase. How Are Cancer Cells Different Than Regular Cells? o Cancer cells behave differently than normal functioning cells. This also means that they likely have different physical characteristics. Cancer cells often have these traits: . They spend less time in interphase-therefore they are dividing more! " They have uncontrolled mitosis-the means they do not stop division after a certain point. . They grow faster than normal cells They can break away from groups of cells and travel to other places in the body They have a different physical structure- often with parts that allow them to grip and grab onto other cells and tissues "Examples of different cancer cells- with many gripping structures What Are Some Causes of Cancer? o There are many causes of cancer. Allof these things increase the likelihood of ceills becoming mutated. Mutated cells may not be normal and develop an incorrect cycle of mitosis. They will then keep reproducing at a high rate, causing the body to put lots of energy into their production and upkeep. Al of this energy being devoted to these cancer cells causes other normal cells to suffer and can ultimately lead to death o Causes of Cancer (things likely to increase the chance of mutated cells Chemicals- many chemicals cause mutation, leading to problems with mitosis Ultraviolet (UV) Radiation- When tanning or exposed to the sun, you absorb UV light. UV light causes DNA to be mutated which can alter the cell mitosis cydle in the future. Viruses-an example is the HPV virus, which is known to cause cervical cancer in females if they are exposed X-rays -they radiate cells, causing mutations - "Explanation / Answer
Answer
1) Cancer
Cancer is when mitosis, a cell process is uncontrolled. Normal cell of the body spend most of their time in interphase of mitosis.
2) 5 ways in which cancer cells are different from regular cells.
Physically, cancers cells have parts that allows them to get grip and grab onto other cells and tissues.
3) Some causes of cancer
Cancer cells undergo uncontrolled mitosis and keeps on dividing. This activity requires lots of energy. As all the enrdy in the body is lost in production of these cancer cells normals cells do not get adequate energy to function and a person ends up dying.
List of cancer causes
All of these items increase the likelihood of cells becoming mutated, which means that cells may not repair and follow a proper cell division cycle.
4) Tumor
When body is undergoig metastasis, tumor cells spread from their original source to other parts of body.
5) Treatment
In order to determine if a tumor is cancerous, a doctor will take a biopsy of it.
In biopsy, a sample of cancerous cells is removed and analyzed under a microscope. It is done to determine the nature of cell ( benigh or malignant).
