Which of the following best describes the development of cancer in cells from both biological and external factors? CHOOSE 2.

• a. Cancer develops only as a result of poor lifestyle choices, like smoking tobacco or a poor diet.

• b. Viruses cannot influence the development of cancer in cells.

• c. Cancer cells grow faster than normal cells, so they usually just die off when they run out of resources.

• d. Mutations in DNA caused by inherited genetic factors can lead to uncontrolled cell division

• e. Exposure to harmful chemicals can damage cellular DNA and trigger cancer.
