LOS ANGELES-Diagnosed with a life-threatening brain tumor 8 years ago, Mario del Valle chose not to be physically defeated. His artist mother, Pilar del Valle, helped inspire him to learn to use his left hand. Mr. del Valle, born in Colombia and now living in Northridge, California, overcame vision and other obstacles to produce watercolors such as the two shown above. Mr. del Valle is a participant in the UCLA Neuro-Oncology Program’s Art of the Brain, which encourages brain cancer patients and their caregivers to use creativity to regain self-worth and personal power. Timothy Cloughsey, MD, is director of the UCLA Neuro-Oncology Program
