How is chemotherapy made?

Chemotherapy refers to the use of cytotoxic drugs in cancer treatment.'Chemo' means medicine or 'drug''therapy' means 'treatment'.

Chemotherapeutic agents or drugs are 'magic bullets' that destroy the fast-dividing cancer cells. However these drugs are unable to differentiate between the normal cells and the cancer cells and they destroy the former too, in their war against cancer. This leads to certain side effects.
