In the first part of the Cancer and Cell Division Lab, you will learn about normal cell division and will compare it to cell division that occurs in cancer cells. You will then visit a website to find out more information about cancer. You will learn why it occurs, why it kills, and new treatments that are being tested and used to treat cancer.
