Living with Cancer and Chronic Conditions Living with Cancer and Chronic Conditions Presentation Transcript

  • Chapter Ten: Living With Cancer and Other Chronic Conditions
  • Cancer
    • Regulatory genes
      • Genes that control cell specialization, replication, DNA repair, tumor suppression
    • Oncogenes
      • Faulty regulatory genes believed to activate the development of cancer
    • Proto-oncogenes
      • Normal regulatory genes that may become oncogenes
    Cell regulation problem causing abnormal cell growth
  • Oncogene Formation
    • Three mechanisms:
      • Genetic mutations
        • Miscopying of genes during cell division
      • Viral infections
        • HIV
        • HPV
      • Carcinogens
  • The Cancerous Cell
    • Characteristics:
      • Infinite life expectancy due to telomerase
      • Lacks contact inhibition
      • Spreads to distant sites via metastasis
      • Commands the circulatory system to provide additional blood supply ( angiogenesis )
    • Benign tumors do not spread but can be dangerous if they crowd out normal tissues
  • Staging Cancer
    • TNS staging system
      • T = extent of primary tumor
      • N = whether or not it has progressed to regional lymph nodes
      • S = presence or absence of metastasis
    • A numerical system tracks extent of cancer spread
      • I = In situ
      • II = Local
      • III = Regional
      • IV = Distant
  • How Cancer Spreads
  • Types of Cancer
    • Carcinomas: 85% of all cancers (organs, skin, nerves, membranes)
    • Sarcomas: Bone, blood, connective tissue
    • Lymphomas: Immune tissues/system
    • Leukemia: Blood and blood forming tissues
    • Melanoma: Sun exposure affecting the melanin of the skin
    • Neuroblastoma: Originates in the CNS
    • Adenocarcinoma: Cells of the endocrine glands
    • Hepatoma: Originates in the cells of the liver
