Cancer

Cancer Biology Overview

Page 1: Cancer

• Cancer is the main topic.

Page 6: Normal Cells vs. Cancer Cells

• Normal Cells

  • Make exact copies through mitosis.

  • Reproduce for about 50-60 divisions.

  • Have specialized functions.

  • Stick together to form masses of cells.

  • Self-destruct when too old or damaged.

• Cancer Cells

  • Do not stop reproducing, considered "immortal."

  • Non-specialized.

  • Do not stick together, behave independently.

  • May move to other body locations.

  • Often have unusual chromosome numbers or mutations.

Page 7: Loss of Normal Growth Control

• Normal cell division involves cell suicide or apoptosis.

• Cancer cell division involves uncontrolled growth due to mutations.

Page 9: Cancer Mutations

• Cancer tends to involve multiple mutations.

• Benign tumor cells grow locally, while malignant cells invade neighboring tissues and metastasize.

• Mutations in proto-oncogenes can lead to the development of oncogenes, causing metastatic disease.
