Biology: Cancer & Stem Cells

Metastasis is

• the spread of cancer from one part of the body to another.
• the growth of tumors in the lungs
• cancer of the blood cells
• cancer that is found in connective tissues

Cancer creates abnormal cells by disrupting

• the cell cycle
• red blood cell formation
• DNA replication
• ATP synthesis

Cancer is

• a premature stop in the cell cycle.
• uncontrolled mitosis.
• programmed cell death.

Which type of tumor is being described:

Slow growing Not dangerous Does not spread

• Malignant

• Benign

Which type of tumor is being described below:

Spreads Dangerous Grows quickly

• Benign

• Malignant

Apoptosis is

• Cell division

• Cell growth

• Cell death

• Cell differentiation

A disorder in which some of the body's cells lose the ability to control growth.

• growth factor

• human growth hormone

• cancer

• tumor

Mass of rapidly dividing cells that can damage surrounding tissue.

• growth factor

• human growth hormone

• cancer

• tumor

Apoptosis is

• the process of programmed cell death

• the process of programmed cell growth

• the process of programmed cell birth

• the process of programmed cell regulation

Which type of tumor causes more damage?

• malignant

• benign

• premalignant
