  3. Tumors • Benign • Remain in one location • Single, well-defined mass • May be surrounded by connective tissue • Cancerous • Abnormal cell structure; may appear undifferentiated • May spread • Edge of tumor not clearly defined

  4. Malignant Tumor Development PLAY Animation—Cancer Figure 18.2

  5. How Cancer Develops • Apoptosis • Mutated or damaged genes • Proto-oncogenes • Normal regulatory genes • Oncogenes • Mutated or damaged proto-oncogenes • Tumor suppressor genes • Regulatory genes slow cell division, • TS genes may be turned off, damaged, or mutated in cancers

  6. Factors Contributing to Cancer • Viruses and bacteria • Chemicals in the environment • Tobacco • Radiation • Dietary factors • Internal Factors • Free Radicals

  7. Cancer Treatments • Conventional treatments • Surgery • Radiation • Chemotherapy
