Help me save my brother's eye!

My brother has been diagnosed with Stage 3 Ocular Cancer.  He has 2 options at this point. He can have radiation treatment for the eye which can only be done in the US or Australia.  The 2nd option is to do the PET scan to ensure that the cancer has not spread to the rest of his body before removing his eyeball. I am trying my best to help him save his eyesight. He currently lives in Singapore with his wife and 2 sons. Please help me raise money for my brother as I wish to have him come here to the US to seek treatment and I have accomodations waiting for him here but I really need help with his medical needs.
