Hi, I've had a swollen lymph node for a few years now and recently had a biopsy but they didn't get enough of a sample but because it's non reactive, I'm having surgery after Xmas to remove it, it's got 3 nodules on it also and 1 measures 2cm x1cm and are mobile, should I be worried I've also lost 2 stone in weight in last few months that I didn't need to lose and only weigh 7st 2lbs currently, please help any advice welcome
