Front

What is an abnormal mass of unregulated cells that continue dividing called?

Back

Tumor

Front

What is the process called when cancerous cells break off a tumor and spread through the body?

Back

Front

What is the main purpose of the G1 phase in the Cell Cycle?

Back

To allow the cell to grow and prepare for DNA replication.

Front

What is the difference between benign and malignant tumors?

Back

Benign tumors do not spread to other parts of the body, while malignant tumors can invade nearby tissues and spread.

Front

What role do checkpoints play in the Cell Cycle?

Back

Checkpoints help ensure that the cell is ready to proceed to the next phase, preventing errors.

Front

What is apoptosis and why is it important in cancer prevention?

Back

Apoptosis is programmed cell death; it helps eliminate damaged or unnecessary cells.
