english: 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.
non_english: We kunnen tumoren doen oplichten zoals deze niertumor zodat je precies de grens ziet tussen de niertumor en de nier die je wilt laten zitten. Of de levertumor en de lever die je achter wilt laten.
