Cancer Notes

 * 10^13 cells in the body
 * cancer cells have DNA damage and become "immortal cells"
 * 2 genes get mutated: proto-oncongene (encourage cell division), and tumor suppressing genes (stop cell division)
 * these two genes damaged in cancer cells
 * after damage, proto-oncogene called oncogene=> and cell division goes crazy
 * tumor suppressor normally inhibits cell division, but when damaged, no longer inhibits.
 * once a cancer cell, have weird properties
 * ends of DNA (telemere) never get shorter
 * nucleus takes up most of cell
 * no function
 * can pile up, don't stop when meet neighboring cell, creating a tumor
