1: something causes a mutation in the DNA of a cell. 2: the cell with a mutation divides uncontrollably creating a tumor. 3:cancer cells break off from the main tumor, enter the bloodstream, and are moved to other parts of the body where they continue to divide

mutation

a change in the DNA that cause the cell to not function properly

cancer

How does cancer begin? 1

cancer begins when mutations change the normal cell cycle causing cells to divide in an uncontrolled way

radiation

cancer is exposed to beams of high energy waves. fast growing cells are more susceptible to being destroyed by radiation

surgery

surgical removal of a tumor. used when a cancerous tumor is detected before the cancer has spread to other parts of the body

chemotherapy

the use of drugs to treat cancer. drugs that kill cancer, or slow their growth, are carried by the bloodstream all over the body

Treating Cancer
