We can light up tumors like this kidney tumor, so that you can exactly see where the boundary is between the kidney tumor and the kidney you want to leave behind, or the liver tumor and the liver you want to leave behind.
Podemos iluminar tumores, como este tumor de ril, para saber exactamente onde está o límite entre o tumor e o ril  que queres conservar, ou entre o tumor de fígado e o fígado que queres conservar.
