How does the pathophysiology of cancer cells differ from that of normal cells? - Answer
Normal cells:
- grow and divide as the body needs and do not grow when the body does not need
- and if cell is damaged/old, it dies
Cancerous cells:

- if cell is damaged/old, it doesn't die (no apoptosis) - it just continues to divide
- these abnormalities are what cause cancerous tumours
