Cercetătorii germani au creat un bisturiu care poate detecta prezenţa celulelor maligne în timpul operaţiilor. Cu ajutorul lui, medicii pot fi siguri că au îndepărtat toată tumoarea. Oamenii de ştiinţă au luat un bisturiu electric, care produce fum când taie prin ţesut şi l-au conectat cu un instrument numit spectometru de masă, folosit în laboratoare pentru analize chimice. Fumul chirurgical este absorbit de acest instrument şi analizat pentru a afla dacă ţesutul tăiat este canceros sau nu. Chirurgul primeşte instantaneu această informaţie, iar pe baza ei va şti cât ţesut trebuie să îndepărteze.
