I’m not sure if I am being unnecessarily anxious or not. I would be grateful for some advice/reassurance? 

I have a hard lump on my right clavicle: it’s not on the joint but a couple of inches along. It has grown slowly over the last three months. I first noticed it when looking in the mirror. 

My GP referred me for an X-ray which showed no bone abnormality. My blood tests were all within normal range. GP then referred me for ultrasound. 

Today I had the scan. The person who did it dismissed it on feeling it as being ‘your bone’. I explained that x ray had ruled out abnormality of the bone. He then checked the x ray and conceded that that there was no bone abnormality. He then scanned my collarbone and was there for some time. Eventually he stopped looking and said it is a ganglion cyst. I queried this because I’m a nurse and the ones I have felt are usually squishy and movable but this isn’t. The clinician said ‘I’m 99% certain it isn’t a tumour because it isn’t vascularised. He advised that if it grows or causes pain to go back to the GP. 

I accepted this and left but his overconfidence left me a bit mistrustful of his clinical skills. 

I am just wondering if ganglion cysts do occur on the collarbone and if they can be hard immovable and able to grow? 

I am worried about malignancy because my we have a lot of cancer in our family on both sides (although neither of my siblings have suffered with it yet). I am also worried because I have been having really bad itching in my left hand which has woken me up at night. The itching on my finger is red now with little blister bumps. It started around the same time as the lump. I’m also having night sweats (but going through menopause). 

I feel ill at ease with just accepting that it is what he said it is because of his overconfidence. Has anyone else had/know of ganglion cysts occurring on the clavicular region?
