| Cancer is | uncontrolled cell division |
| Cancer cells have lost the ability to control | cell division |
| Metastasis is when | cancer spreads beyond its original site (like lung cancer spreads to the liver) |
| Surgery, one way of treating cancer, is | when the cancer (tumor) is physically cut out |
| Chemotherapy, one way of treating cancer, is when | drugs are used to kill cells |
| One downside of chemotherapy is that it | kills healthy cells along with cancer cells |
| Radiation, one way of treating cancer, is when | cancer cells are hit with high energy waves that destroy them |
| Angiogenesis is when | new blood vessels form |
| T/F: Cancer cells (tumors) can cause angiogenesis | True |
| Endostatin is a drug used to treat cancer and works by | blocking the formation of new blood vessels so that the cancer "starves" |
| If a tumor can't form new blood vessels it won't be able to | grow or spread |
| A carcinogen is anything that | can cause cancer or increase the risk of developing cancer (ex: sun exposure) |
