I found a pea sized lump on my left breast last night, and went to the gp today for a breast clinic referral.
Nearly two years ago I had the same experience, had an ultrasound and biopsy and everything was fine. In fact I went for the ultrasound for a lump in my left, which was nothing, and ultrasound picked up one in my right which was the one they checked out.
GP says it's probably nothing to worry about, well he'd probably say that anyway wouldn't he?
My mum had similar experiences at my age, had several scares, but lumps all turned out to be benign.
I'll be a couple of weeks waiting for the referral, but in the meantime am trying to convince myself that I'm just prone to innocent lumps
