Cancer Cells vs Normal Cells

I found an article about cancer cells vs. normal cells. This article was updated on October 29, 2013 by Lynne Eldridge MD. This article talks about the different functions from cancer cells and normal cells. It talks about the rate of growth and the growth its self of both normal and cancer cells. How the cancer and normal cells interact with other cells. It talks about the repair and cell death of the cancer and normal cells. It talks about the substances that they make to stick together in a group. The ability they have to spread and the appearance under a microscope. It also talks about how they evade the immune system and how they mature. I learned that when we get a cut our cells began to reproduce to repair the cut. Once our cut is cure the cells stop reproducing, because there job is done. Cancer cells also began reproduce to repair the cut, but they don’t stop reproducing once the cut is cure. Cancer cells keep reproducing often causing a cluster of cancer cell that are being form. I learned that this happens because the cancer cells don’t interact with other cells so when the other cells give them the signal to stop growing they don’t stop. On the other hand when normal cell hear the signal to stop growing they do stop. I also learned that normal cells make a substance that adhesion them molecules that helps them stay in the area of the body where they belong. On the other hand the cancer cells aren’t able to make this substance to help them stick so they flow and start to travel through the bloodstream, lymph, and to other regions of the body. Once they arrive in one of the regions of the body they began to grow. That’s way when seen under a microscope they are much larger or smaller than normal cells. I learned that the differences of the normal cells and the cancer cells are because the cancer cells function the opposite way that the normal cells do.
