HI, Michelle, Glad to hear your brother got the peg as that will probably make it easier for him [and caregivers] to get the calories and liquids he needs. When you get a report [the lymph node stuff] that you don't understand- ASK for clarification and write it down so that you understand what is being said. When his radiation starts, there will no doubt be some questions we can help with? Is chemo still part of the plan? The fact that he [and your family]is scared is very normal. We've all been there. It will take alot of courage and strenght going forward. Best wishes to your family. Amy in the Ozarks
