Radiation high energy radiation is used to shrink tumours and kill cancer cells. Radiation therapy damages dna of both cancerous and non- cancerous cells. Chemotherapy drugs are used to treat cancer. As cancerous cells are dividing rapidly, chemotherapeutic drugs target rapidly dividing cells. As the treatment of cancer involves targeting cell proliferation, an understanding of the cell cycle is essential for understanding the mechanism of drug action. replicate.
