I had a .6mm removed in 2018 at Johns Hopkins so 1a. They said no slnb due to depth. Over the years I have requested ultrasounds because my underarm nearest arm scar felt “full” but they said not necessary. I requested an ultrasound again last week due to a strange bump in my underarm near the scar and my ultrasound came back today saying suspicious lymph node rated BIRAD 4 biopsy needed. (Interestingly it was not the lump I was having them check.) I am literally devastated, and the doctor who spoke to me provided little reassurance. I am fully assuming at this point that the melanoma has spread to my lymph nodes and perhaps beyond, as it has been four years since my primary. I guess I am hoping for some support and/or advice, although really all I can do is wait. They cannot get me in for the biopsy until end of next week. Thanks for listening as I don’t really know anyone else to talk to about any of this.
