So my daughter who is 21 has developed a lump under her chin started off a small lump a few days ago yesterday it was big today it looks like she has 3 chins. Couldn't get through to the doctor this morning. It's painful when I touch it, it's swollen and it stretches across her neck now. I've read all sorts on line and don't know whether to panic or not. Of course I am because I'm her mum. I'm reading lymphomas and cancers all kinds of words. She's completely freaked out and I'm trying to remain calm. Does it sound scary to anyone?
