Worried girl

Hi, 

im 22-23 in March, my family have a very large history of cancer and a couple months ago I found two lumps in my left breast but I was too scared to go the drs,I have been also collapsing a lot for the past year, I get nauseous a lot, I have frequent pain in my left breast and occasionally in my left arm and shoulder  . I have recently been to the GP after having spoken to my mum and they're sending me to the hospital for tests.. I was just wondering what are the chances of me actually having cancer with me being so young.. 

 

Chy..
