Vitor Lobo, Son of Grace Brethren Pastor Ray and Nelsa in Belem, Brazil recently found more tumors in his rib, sternum and lung. He has undergone several surgeries for tumors in the last few years, including an amputation of his forearm last January. This meant the loss of his ability to play guitar in the praise and worship band at church and with his own band. Although the tumors have spread they are not considered cancerous, but can be aggressive and sometimes fatal. They are an uncommon type named big cell tumors.
