What is the major of chemotherapy agents in anti-cancer drugs ?

24>Google often gets you people's 'guesses'.





The treatment often varies depending on the type of tumor that is being treated and the suitability of the person to the medication. There are hundreds of options and a list would be pointless.





Broadly, they can be split down into;


*Antimetabolites - these drugs prevent the formation of biomolecular components required for DNA replication and so stop cells dividing


*Alkylating agents (old) - add alkyl groups to many electronegative groups under conditions present in cells. This stops cell division by directly attacking the DNA.


*Genotoxics - Directly damage DNA and prevent cell division.


*Spindle Inhibitors - Prevent the spindle, a part of mitosis, forming, thus preventing cell division.


*Others - (usually, method of action, not clear)
