As I noticed you haven't yet received a reply I just wanted to stop by and welcome you to Cancer Chat.
Hopefullly our members who can relate to what you are going through at the moment will be along shortly to share their experiences with you and give advice, but in the meantime feel free to use the search engine from the left hand side of the blue banner at the top of this page and insert 'gastric cancer' it will show up previous posts which you might find useful to read.
