Thank you so much for replying to me, I have a huge lump in my upper arm, the doctors told me it was a cyst and scans have comfirmed it is definitely not a fatty lump or cyst and that between the 2 weeks of my ultrasound and mri it has grown, the swollen lymph node I only noticed since the doctor asked me if I had any swollen lymph nodes so no idea how long it has been there! I also have been feeling very unwell and chest pains considering what they are looking for it's very hard not to be worried, I have young children, the only thing that keeps me positive is this couldn't happen to me with young babies and it is so rare, my mum was diagnosed with cancer herself 3 months ago, it's all so much!
