Hi, I've had this lump in my neck since late June and it's still not gone away! It's underneath my jaw in the soft skin area. It's hard and doesn't move and isn't painful either! Of course my mind went straight to the thought of cancer. Ever since my nan was diagnosed with breast cancer not long ago I have been suffering with severe health anxiety to the point where I can't sleep. Any reassurance and advice would be greatly appreciated. I'm only 15 so this is quite scary .
