Introduction to Cancer Biology

What are the fundamental living units that make up organs and other body parts?

• Tissues

• Molecules

• Cells

• Organelles

What process do normal cells undergo to reproduce their genetic information and divide into two identical daughter cells?

• Meiosis

• Mitosis

• Photosynthesis

• Respiration

How do cancer cells differ from normal cells in terms of division control?

• Cancer cells divide only when signaled, like normal cells.

• Cancer cells divide indefinitely, even without proper signals.

• Cancer cells divide slower than normal cells.

• Cancer cells only divide in response to external threats.

What cellular component is considered the "brain" of the cell and contains the blueprint for an individual?

• Mitochondria

• Cytoplasm

• Nucleus

• Ribosome

What is the consequence if both copies of a tumor suppressor gene are damaged?

• The cell will repair itself automatically.

• The cell will continue to divide abnormally.

• The cell will stop dividing and die.

• The cell will become a normal cell.

What is the process called when a growing tumor sends signals to nearby blood vessels to grow new extensions to deliver food and oxygen?

• Metastasis

• Angiogenesis

• Apoptosis

• Mutation

What is the term for the movement of tumor cells from a primary tumor to other parts of the body to form new tumors?

• Angiogenesis

• Apoptosis

• Metastasis

• Cellular division

What is the orderly process of programmed cell death that eliminates defective cells and helps prevent cancer?

• Metastasis

• Angiogenesis

• Apoptosis

• Mutation
