I hope someone can help me. I am writing a book in which the main character dies. I want him to know that he is dying and that he has very little time left. However I want the death to occur very suddenly when he is about to board a plane. I thought of the possibility of a Brain Tumour and have done some research into this possibility. The problem is I don't know if there is a type of brain tumour that would exibit few physical syptoms so close to death. I would be very grateful if any experts could help me and they would have course be thanked in the books credits.
Hopefully, Emma
