What is cancer? The cell cycle is disrupted resulting in too much cell division As a result of cells divide too quickly = tumors

Types of tumors Benign Malignant Abnormal mass of cells remain at original location Malignant Abnormal masses of cells move normal cells and grow and move beyond their original location This movement is called metastasis

Treatment Chemotherapy Chemical agents to stop cancer cells from dividing Interrupt cell cycle before M phase Problem: Can’t tell the difference between cancer cells and normal cells = destroys other fast growing cells Hair and blood cells

Treatment Radiation Energy (Ionizing radiation) kills cancer cells and shrinks tumors Injures/destroys cells by damaging genetic material so they cant grow/divide Problem: Damages both cancer and normal cells but most normal cells can recover Ovaries/Testes
