Unlike classical chemotherapies, the chemotherapies used for cancer treatment at World Health Network's partner hospitals' medical oncology departments and oncology centres are designed especially for each patient as target-aimed smart medicines, molecules, hormonotherapy, and immunotherapy to ensure the patients' comfort.

Chemotherapy can be applied to minimize the tumour before the surgery or for protective purposes post-surgery. It can also be resorted to before, after or during radiotherapy, which is one of the local treatment techniques.
