Hello AK, I'm really sad that you have to be here, your Brother is so young.
However this disease doesn't take any notice of age. I do know that on initial diagnosis one does get sent into a whirlwind of panic and rambling thoughts.
I reiterate what all the above posters have said. Take a deep breath and breathe .
Can not stress enough the importance of being seen at a Comprehensive Cancer Center with the whole team approach. Look through the list Christine has posted and get your Brother to one of them. This disease needs to be treated correctly from the get go to give your brother the very best chance of Cure. Yes, cure. This disease is curable. Hang onto that thought and take it one day at a time.
My very best wishes to you, your Brother and your family.
