Hi, 

I found a lump on my upper breast / pectoral muscle in November 2021. At the time I had it investigated via ultrasound and it showed normal breast tissue. I still have this lump almost a year on and it doesn't seem to have changed, but I'm really anxious not knowing what it is and whether it was misdiagnosed. 

Does anyone else have experience of this? It is about 5-7cm, firm and non moving. It seems to be in a fixed position on my chest rather than in my breast. I also have PCOS which I started taking the estrogen based pill to sort out, and was hoping the lump was hormone related but its not going away. 

Any advice would be really appreciated. 

Thanks
