Hi, I've had a big lump in left sidemy neck since October. It gets bigger when I eat or get stressed. I've had blood tests, normal. Have a scan on Wednesday butSince the end of January I have felt a growth under left side of tongue. It doesn't hurt to swallow but there is pressure there. I have lost 1st 5lbs in 3 weeks and constantly feel nauseous. I have been having chest pains which move down to stomach pains. Have had 2 periods in the last 3 weeks. I'm so scared. My nan has just died of lung cancer, spread to her brainn
