Hello

I noticed a dent/dimple under my arm about a week ago and thought nothng of it but at weekend I took photo and could see it didnt look right. Also I have had pain at that spot for about 6 months and under my breast and around shoulder but put it down to exercises I was doing getting older etc! My breast has also grown bigger and is more noticeable now so I made apoointment and saw GP yesterday. Before I went I looked again and thought no I cant see it and Im wasting time but as soon as I laid down the GP said no can clearly see the dimple and other breast changes :( Had blood taken this morning and now waiting for appointment with breast clinc. Anyone else had symptoms like this or what can I expect at clinc, will they do test and if so what kind

thanks
