My nephew's son has a rare brain tumor

Please pray for my nephew and his family. A year ago his youngest son ,6 at the time, was rushed to Riley Children's hospital with a brain tumor. It was removed and he spent from Oct 23-Jan 17 in Riley. Came home and in July the tumor had returned. Went to Chicago for proto. Beam radiation. And we just lward the rumor again has returned. It is a very rare turmor. He's 7 now and a fighter. We just need God's hand on this child. He's such a special boy. He had had4 brain surgeries in the last year. The Doctors said they can't keep going in every 4-6 months to remove the tumor.
