Thank you so much. I really appreciate your response. In passing this info onto my dad, as he's not tech savvy so relies on me. I'm just relieved he's been referred onto a specialist now, so they'll get some kind of treatment plan in place. He seemed in a better mood this afternoon, despite the bad news, and said he feels better that he knows what it is now. Thank you again for replying, it really means a lot. I've used various forums for my dads bowel cancer and mums lymphoma over the last few years, they're invaluable! Take care Amanda
