Chemotherapy
- Treatment of cancer cells with the use of chemical agents that damages cell
DNA and regulation. Systemic effects but can cause damage to normal health
cells.
Alkylating Agents
- Inhibits cell division
Antimetabolites
- Counterfeit metabolites that fool cancer cells impairs cell division
Antimitotic Agents
- Interfere with the formation and actions of microtubules so cells cannot
complete mitosis during cell division
Anti-tumor Agents
- Drugs that were originally developed as antibiotics that have effects on
cancer cells. they damage the cell's DNA and interrupt DNA/RNA synthesis
Topoisomerase inhibitors
- Disrupt the enzyme (topoisomerase); this leads to DNA breakage and cell
death
Other chemotherapeutic agents
- Those with mechanisms of action that are either unknown or don't fit other
categories
Surgical classification types
- Prophylaxis, diagnosis, cure, control, palliation, assessing therapy
effectiveness and reconstruction
Prophylactic surgery for cancer
- Removes potentially cancerous tissue as a prevention of cancer development
