welcome fellow brit! actually,the best advice as regards this site is just for you to take a look around, read the posts and don't be afraid to ask questions. Feel free to PM me anytime if you like. I'm reasonably knowledgeable, a BC veteran of some 14 years I first got diagnosed at 29 years of age. so maybe it's 15! As far as being a BC newbie goes, that phrase encompasses many stages and states of the disease as people arive at it so it's hard to make a definitive list. I guess a top tip would be to stop smoking if you do as I think most of us are agreed, doctors, scientists and BC patients, that it makes things worse. the next thing I would say is, if you are considering improving your diet to make yourself feel better and fighting fit, then make changes gradually. that has always worked best for me. and make changes with a view to feeling good as a principal motivation. you'll certainly find all kinds of concise info concerning all stages as you browse this very active site.
all the best and welcome
