Cancer+Statistics+EP

cancer is a long process when a cell in an organ or tissue becomes damaged makes it break free from the control of all the cells. misbehaving cells. organs can control eating, and breathing, digesting food, and the movement of our blood tissue: muscle, nervous, epithal, and connective tissue. a normal cell will divide when it gets the signal to do so. process through mitosis. cancer cells will not follow the rules but will divide when ever they want too. normal cells are also told when o stop dividing so there are not to many cells made. cancer cells do not follow these rules either but they keep making cells. contact inhibition nucleus is the brain of the cells chromosomes- 46 chromosomes in each human nucleus. 23 from each parent genes are made of DNA. all cells contain the same information just depends what function they have in the body. mutation can include those of tobacco or artificial services proto-oncogenes lead to the production of oncogene that gives proper signal to mutate. the cell divides without signal. tumor surpressors (they tell the cell to stop dividing). if a single copy of a ts is damaged then the other copy can stop the cell form acting out of function. but if the other one is damaged as well then they will not stop and keep making cells. angiogenesis- means the tumor cells can start to control by getting the body to feed it. metastasis- movement of tumor cells to move throughout the body. once it is fed with blood vessels
