Pray for our family

We're not sure what to do. We've been in a particular church close to a year now.I was actually physically healed while being here. But my husband and I feel it is time to move on, for reasons I cannot share. After much prayer and fasting, we asked the Pastor to help us pray. He told us that God sent us to him and if we leave that God would remove His healing hand from me, and the tumor would grow back. I have not seen anywhere in the Word of God where He removes a healing. If there is, please tell me. Please pray that God will have His way with us. We feel broken and confused.
