Referred on a two week referral

I found a lump in my breast and I've been having bloody discharge from my nipple. I went to my GP today who has referred me, I am very worried even though the GP doesn't think it is sinister ( she still wants to get me checked as I have a family history of cancer). I'm worried it might be cancer, I know it's unlikely but I just want to know now and get all the tests over with.
