True
False
The term localized describes which type of tumor?
Malignant
Benign
All of these are things cancer cells do EXCEPT...
Divide uncontrollably

Do not undergo normal cell death
Can be spread from person to person
Telomeres get longer when the cell divides
True
False
Stem cells are important for:
growth
development
repair
all of the answers are correct

True
False
Cancer cells do not enter apoptosis for two main reasons:
Maintain telomeres
Ignore Signals
Divide Rapidly
Metastasis
