Brain surgeon Dr. Andrew Parsa dies at 48 I am shocked by the news. Dr Parsa was one of the brightest stars in the brain tumor world. I was just talking to him at a conference recently about his vaccine work - he was so excited that his vaccine was going to have a big impact on the fight against brain cancer. He came so far and unfortunately won't be able to see the impact he made on the field. My condolences to the family.
