Verified step by step guidance1
Understand the characteristics of tumor cells: Tumor cells often exhibit certain behaviors that distinguish them from normal cells.
Review the concept of angiogenesis: Tumor cells can stimulate the formation of new blood vessels to supply nutrients and oxygen, a process known as angiogenesis.
Examine genetic stability: Tumor cells are typically genetically unstable, meaning they have a high rate of mutations.
Consider apoptosis: Apoptosis is the process of programmed cell death. Tumor cells often evade apoptosis, allowing them to survive longer than normal cells.
Analyze contact inhibition: Normal cells stop growing when they come into contact with other cells, a phenomenon known as contact inhibition. Tumor cells often lose this ability, allowing them to grow uncontrollably.
