Hi jaqui a referral is just a safety check they might not find anything harmful, you don't say what you feel is wrong with you, best wishes... Billy 

Hi billygoat I have a hard lump in my neck, I’m just so worried that it will be bad news. My mum and nan both passed away due to cancer at age 55, I’m now 47. I know I shouldn’t worry but it’s really hard not to. Thank you for replying
