Personalised medicine is becoming precision medicine n the fight against cancer. The present concern is with combining the several drugs that the patient may require into a cocktail to fight their disease. How these drugs interact with each other and how they then affect the patient as a result, is unknown. Lab tests only go so far, so MIT researches believe that they have found a way to test the efficacy and the interactions of a cocktail of cancer drugs in the patient’s actual tumour. They have invented a device the size of a rice grain that can hold several doses and slowly release these into the surrounding tumour.
