Long term survival depends on many factors. The younger you are, the better your chances. The more tumor removed, the better your chances. The healthier you were prior to diagnosis, the better your chances. The better you came out of surgery in regards to physical/mental deficits, the better your chances.
Survival statistics are unfortunately quite accurate for the majority of the population, but do not apply to the entire population as evidenced by long term survivors on this forum and others. That's where ATTITUDE comes into play. Believe in God, believe in yourself, be a fighter and just keep going as best you can. Normalcy is important...try as best you can to get back to your normal routine before diagnosis. You CAN be the exception to the statistics. There are others who are, why not you.
