DIPG and DMG are particularly aggressive and difficult-to-treat brain tumors typically found in children.
The cause is not known to be hereditary or environmentally influenced. There is nothing a parent did or did not do that caused DIPG/DMG to occur in their child.
The lifespan for patients with DIPG or DMG varies. Radiation has been shown to improve quality and quantity of life for some but not all. Experimental trials are continuously being initiated in the hopes of prolonging survival.
