An average of 250 vials of the breast cancer medicine Herceptin are distributed to patients every month.
All breast cancer patients are given the drug for free once it has been established that it is the best treatment for them.
The government buys about 2,200 Herceptin vials a year.
The drug is administered by means of an injection, normally once every three weeks for a year, according to the needs of the patient. It is given to patients at the third stage of cancer, after they would have undergone surgery.
