I have recently been told that I have gallstones. My CT report indicates layering cholelithiasis. I would not be overly concerned but I am a survivor of 3 primary cancers (two in my reproductive organs - one breast cancer). I understand that gallstones may actually be metastisis. Should I ask my oncologist for an ultrasound to get more info or am I just overly concerned. All of my cancers have been caught very early and were treated with surgery, chemo and radiation. What do you think? Am I overthinking this?
