A benign tumor differs from a malignant tumor in that a benign tumor

• is cancerous

• spreads from the original site

• does not metastasize

• never causes health problems

A ________________is a critical point where stop and go signals can regulate the cycle

• tumor

• checkpoint

• growth factor

• oncogene

When it occurs at the proper time, programmed cell death (apoptosis)

• will disrupt homeostasis
• may cause defective genetic info to be passed to the next generation of cells
• is an important regulatory process that maintains the health of a multicellular organism
• can contribute to the development of cancer
