3. Cancer: What is it? Intro videoclip Intro videoclip Out of control cell growth Normal cells die out Cancer cells create more cancer cells

4. What controls Cell growth? There are 2 factors that control cell growth: CDK & Cyclin CDK & Cyclin Apoptosis=cell destruction if error detected (kills self)

5. Causes of Cancer-Theories of Cancer 1)growth controllers are mutated and create cancer genes 2) tumor suppressor gene turned off 3) Environmental factors/mutations 4) Viruses

9. What is the molecular basis of cancer? What is the molecular basis of cancer? –Cancer is a genetic disease. Mutations in genes result in altered proteins – –During cell division – –External agents – –Random event Most cancers result from mutations in somatic cells Some cancers are caused by mutations in germline cells

Radiation Exposure to ionizing radiation Exposure to ionizing radiation Movement of electrons Movement of electrons Radioactive atoms such as gamma rays are used to irradiate cells Radioactive atoms such as gamma rays are used to irradiate cells Xrays irradiate cells Xrays irradiate cells Bad cells are more susceptible than good cells Bad cells are more susceptible than good cells

26. Chemotherapy (treatment) Chemotherapy (treatment) Usually used after surgery to insure the removal of all cancer growth Usually used after surgery to insure the removal of all cancer growth Chemicals or drugs are used to kill those cells that have left the original tumor (oral or injected) Chemicals or drugs are used to kill those cells that have left the original tumor (oral or injected)

38. Cancer Stages Cancer Stages (1:11) … Cancer Stages Stage 0 = confined to area in which it started Stage 0 = confined to area in which it started Stage 1 = small tumor without penetration into surrounding tissue Stage 1 = small tumor without penetration into surrounding tissue Stage 2 = tumor has penetrated into surrounding tissue (like muscle) Stage 2 = tumor has penetrated into surrounding tissue (like muscle) Stage 3 = tumor has spread to lymph nodes Stage 3 = tumor has spread to lymph nodes Stage 4 = tumor has spread past original area and lymph nodes to other organs Stage 4 = tumor has spread past original area and lymph nodes to other organs
