I'm a 26 year old woman, and for the last 4 or 5 weeks I've been experiencing pain (tenderness, almost like a very sore pulled muscle, with the occasional sharp stabbing sensation) in my right breast and armpit. Tuesday night, while showering, I found a lump close to my nipple, so booked a doctors appointment for this morning.

Today, Friday, the doctor had a feel and said the whole breast was very lumpy. But, in particular, there was a large, solid lump where I found it, and another, deeper one (that she could only feel when I was lying down) where breast and armpit meet.

She seemed quite visibly concerned (which is alarming), and referred me to the breast clinic to be seen within 2 weeks.

I'm petrified.

When I was 20 I found a lump in the same breast (a "breast mouse"),  and had it removed at 22 when it grew too large (8cm!) and too uncomfortable when it came to wearing bras (as it sat right on the cup line). But I never had any long term pain with it, and the texture was much, much smoother than the lump I can feel now. Plus, the bit that worries me the most, with the last lump I was put through as a non urgent referral. The hospital appointment took months. But now my GP wants to get me seen as soon as possible. 

I'm freaking out. My aunt and uncle both died of breast cancer when they were in their late twenties to mid 30s, while my grandmother had it but beat it, so I'm scared I'm doomed to have it too. I can't stop thinking about the worse case scenarios and panicking about treatments or dying and, stupidly and vainly, potentially losing part or all of my breast. I'm already self conscious about the scar and rather large dent that the previous lumpectomy left. I feel like my body is letting me down. 

I have no one I can really talk to as my family don't know about it (they currently have enough issues without me adding to their worries), and my partner knows but isn't exactly... kind. I feel so alone and so frightened. 

Does anyone have any advice?
