Understanding Human Biology and Cancer

What is the primary difference between cancer cells and normal cells regarding division?

• Cancer cells use mitosis, not meiosis

• Cancer cells divide slower

• Cancer cells require more signals

• Cancer cells divide without needing signals

What is angiogenesis in the context of cancer?

• Cell mutation

• Cell death

• Formation of new blood vessels

• Decrease of blood supply

What is metastasis?

• Repair of cellular damage

• Spread of tumors to distant locations

• Decrease in tumor size

• Process of cell division

What can cause mutations in cells?

• High sugar intake

• Consumption of vitamins

• Exposure to radiation

• Lack of exercise

What is the role of tumor suppressor genes?

• Enhance oxygen uptake

• Suppress cell division

• Increase nutrient absorption

• Promote cell division

What happens if both copies of a tumor suppressor gene are damaged?

• Cell becomes immune to cancer

• The cell dies immediately

• The cell stops dividing

• Uncontrolled cell division

What is apoptosis?

• A growth factor

• A type of cancer

• Cellular suicide

• Cellular repair mechanism

What are proto-oncogenes?

• Genes that repair DNA

• Genes that cause cancer

• Normal genes involved in cell division

• Genes that prevent cancer

How do cancer cells differ in their response to drugs?

• They are all resistant

• All respond the same

• They cannot be treated

• Different cells may respond differently

What typically initiates the process of cancer development?

• Hormonal imbalance

• Excess nutrient absorption

• Damage or alteration in a cell

• Cellular overgrowth
