Really hoping someone can help me and put my mind at ease. I'm 27, female, normal weight, no family history of breast cancer and haven't had kids yet.

6 or 7 months ago, I noticed that I can squeeze a little clear discharge from my nipple (one breast only). I didn't think much of it but I told the GP anyway, and they referred me to the local breast clinic. At the breast clinic, they squeezed a bit out and tested it and said there was blood in it, which seemed to concern the consultant. I was sent for an ultrasound, which showed nothing. Then I was told to return in 6 weeks and they'll have a look again. Came back after 6 weeks and as I hadn't had any discharge in the meantime, they said I'm good to go home, but to keep an eye on it. The doctor also said that if it happens again, the only way to find out would be to remove all my milk ducts in that breast and send them for tests, which would mean I wouldn't be able to breast feed from that breast in the future.

A few weeks ago, I noticed a very very small amount of liquid on the tip of my nipple (like, a tenth of a drop). I squeezed and more came out (maybe 2 or 3 drops), but this time it was no longer clear, it was kind of rusty so it pretty clearly had blood it in. I obviously panicked, called my GP, got referred back to the breast clinic as an emergency (which still means a 3 week wait in my case). Now with my breast appointment getting closer and closer, I'm freaking out and can't think of anything other than this. I really don't want to have surgery because I'm scared and I'd also like to be able to breast feed in the future. 

Has anyone else been through this in their 20s? Is there really nothing else that can be done to avoid the surgery?
