Hi ... this is my first post......

I have a fairly complicated gyne history .... the result I'm 29 and on zoladex injections awaiting a hytroectomy 

I found a lump in my left breast  very suddenly its about a inch above my nipple pretty much in the centre of my breast on top its doesnt move it doesn't hurt although if I try to squish it my shoulder and under my arm aches ...its almost eye shaped .... nothing else has changed 

Iv read zoldex is used to treat breast cancer so I'm guessing it can't be cancer ??  bt the gp new this and still did a urgent refferal ??? I also take hrt ? (I was originally told you can't stay on zoldex for more than 6 months I'm just about too have my 13th injection due to covid and delays)  .... could the lump be caused by the zoldex and menopause or the hrt .... it just doesn't sound or feel like any of the benign breast conditions I can find and I'm starting to panic massively don't no how I'm going to get through the next 5 days my brain just  won't function or think about anything else  ... ....just find myself looking for things that  it cld be that wldnt cause any problems ... bt There doesn't seem to be anything that fits 

I have appointment on Thursday..... I can't think straight or concentrate but then get angry at myself because I'm sure it will be nothing and il of ruined everyone's week for nothing 

Any advice or anything appreciated
