Study Notes
Characteristics of Cancer
- Cancer is a large group of diseases characterized by uncontrolled growth and spread of abnormal cells
- Cancer involves proliferation (rapid reproduction by cell division) and metastasis (spread or transfer of cancer cells from one organ or part to another not directly connected)
Definition of Aberration
- An aberration is a departure from what is normal, usual, or expected, typically unwanted or unexpected
- Aberrations involve distinctive morphologic alterations of cells and aberration of tissue patterns, resulting in cancer cells
Key Terms Related to Cancer
- Brachytherapy: delivery of radiation therapy through internal implants placed inside or adjacent to tumors
- Carcinogenesis: process of transforming normal cells to malignant cells
- Carcinogens: chemicals, physical factors, and other agents that cause cancers
- Chemotherapy: use of medications to kill tumor cells by interfering with cellular functions and production
- Alopecia: hair loss
- Anaplasia: pattern of growth in which cells lack normal characteristics and differ in shape and organization with respect to their cells of origin
- Angiogenesis: (not explicitly defined in the text, but related to cancer)
- Apoptosis: (not explicitly defined in the text, but related to cancer)
Important Concepts
- Cancer cells develop due to aberrations, which involve deviations from normal cell and tissue patterns
Test your knowledge of cancer by learning about cellular aberration and the characteristics of uncontrolled cell growth, rapid reproduction, and metastasis. Explore the distinctive morphologic alterations of cancer cells and how they deviate from the normal type.
