Scientists developed fast test to see which drug kills your tumour

Researchers have developed a tiny device that can test several drugs on a tumour at once.

The new implant - around the size of a grain of rice - is injected into the tumour, administering small doses of 16 different chemotherapy drugs.

Researchers at the Massachusetts Institute of Technology say this shows which drug works best without exposing the patient to potential side-effects from higher doses.

After 24 hours, the device is removed with parts of the cancer tissue attached. These are then analysed to see how many of the cells have died from each drug. So far the technique has been used for melanoma and breast and prostate cancer in mice, with results showing it accurately predicts each drug's effectiveness.
