Study Notes
Neoplasia
- Uncontrolled, chaotic growth of cells
- Cancerous cells don't respond to normal growth control mechanisms
- Neoplasm refers to new, abnormal growth
- Cancer in children is rarer than injury or infection
- A leading cause of death in children under 15
- Overall 5-year survival rate for childhood cancer is 83%
- 5-year survival rate for acute lymphoblastic leukemia is 90%
Cell Growth
- Normal cell cycle has an interphase (resting) and mitosis (dividing) phase
- Interphase has 4 stages: GO, GI, S, and G2
- Cell lifespan varies based on tissue type
- Cell cycle speed changes due to factors like hypoxia, genetics, immunity, physical agents, and chemical agents
- Organs have cells in both resting and active states
- Cells recognize their own type
