G1G1 G2G2 M S Cell cycle G 1 checkpoint G 2 checkpoint Metaphase checkpoint Are all the chromosomes attached to microtubules? Are sufficient nutrients available? Is the cell large enough? Are growth factors present? Is cell division necessary? Is the cell large enough? Was DNA replicated correctly? Tumor suppressors- stop Growth factors- go

Cell Cycle Control and Mutation - Many Mutations Are Required for Cancer to Develop  Progression from benign tumor to cancer requires many mutations.  Immortalization  Loss of contact inhibition  Angiogenesis  Loss of anchorage dependence

Class Data 1.Does Family History play a pivotal role in the development of cancer? Explain 2.What were the top three cancers? In your opinion why were these cancers the most popular? 3.What was the most common possible risk factor? 4.Cancer is often described as the disease of the aged. This statement may be inconsistent with your class data. What explanation can you offer in support of this statement?
