Cancer is a multistep process

  • Tumors originate from one cell, but as a tumor develops the cells within it can start to change / evolve becoming increasingly unstable!

  • 1. How is cancer a multistep process? What are some of the “steps” involved?

  • 2. How does evolution / natural selection relate to cancer?

  • 3. Can cancer be contagious?


Cancer is a multistep process1

  • Increased incidence with age

  • Increased incidence with exposure to environmental carcinogen or inherited mutation

  • Lag time between exposure and cancer development

Cancer s toll

  • 2nd leading cause of death in the U.S.

  • Men have a 1 in 2 lifetime risk of developing cancer; and women have a 1 in 3 risk

  • Only about 25% of all cancers are “hard core”
