Study Notes
Cell Cycle and Cancer
- Genetic mutations and epigenetic changes result in benign and malignant cells.
- The cell cycle consists of three stages: interphase, mitosis, and cytokinesis.
Definition of Cancer and Tumors
- A neoplasm or tumor is an abnormal mass of cells that can be benign or malignant.
- Cancer is defined as a group of diseases characterized by uncontrolled growth and spread of abnormal cells.
- The defining characteristic of cell division in cancer is uncontrolled growth and proliferation.
Dysfunctions in Cancer
- Two major dysfunctions present in the process of cancer are: uncontrolled cell growth and inability to undergo programmed cell death (apoptosis).
- The physiology of cancer involves the development of a tumor, which can invade and metastasize to other parts of the body.
Leading Causes of Death
- Heart disease is the second leading cause of death after cancer.
