i know this looks long but i really need an answer and it will only take like 3 mins to read at the most 
hi can someone answer 3 questions please because im worried about this
1.i have two lumps just under my skin under my chin(under the jaw)
they are moveable,no bigger than my little finger, about 1cm distance apart, firm, but one is softer than the other. i think i might of had them years but i have only really discovered them now. they only hurt if i press them or push my chin into my chest, otherwise they are pretty unnoticable. does anyone know what they could be and if they are dangerous? any info would help please.
2. i also have one that doesnt hurt as much as those but feels the same on the back of my neck just where my hair starts to grow.
3. can you have more than one cancer at the same time? is it possible to have more than one cancer lump in the same area? how long can you have a cancer lump before you start to feel ill?
additional info - im 13,i weigh 9 or 10 stone im reasonably fit, the only serious illness i have ever had before is kidney failure(e-coli) and the only person in my family who has ever had cancer before in my family is my grandma who had breast cancer, but she got over it
please answer because im worrying loads
