Hello!

I hope you're okay, it is a horrible thing to have to go through. I like you am in my 20s (21), statistically in our age group it is unlikely to get a diagnosis of cancer. However your symptoms of a lump in your breast and lymph nodes means you are showing more than one symptom which is why you would have been referred as suspected cancer. What i've learnt is that it is really difficult to predict what is going to happen. Throughout my whole process i've been getting told that my lump is very likely to be a fibroadenoma (benign), but at my breast clinic appointment the way the tumour looked on ultrasound meant that they wanted to do a biopsy to determine if its cancer or not (I was originally referred as a non cancer suspected patient!). 

It can be useful to remember when you have tests, that the majority of biopsies come back benign, and in our age group that chance is even more likely. It is also useful to remember that fibroadenomas are most common in women in their 20s/30s. However I completely understand preparing yourself for the worst as I am doing the same. I'm not really sure about the lymph nodes, whether that can also be caused by hormones or not as thats a symptom i don't have, but i'm sure you will be told by the consultant. Upon examination my consultant told me that my lump was mobile and moved around a lot which is a good sign (fibroadenomas are often referred to as breast mice because of this), so that might be worth asking about too.

Good luck I really hope it all goes okay for you xx
