Does anyone else have blastic process?

jubles

I am a 13 year bc survivor. Two years ago blastic process was found in my left pelvis. The oncologist my GP sent me to told me not to worry about it. I was supposed to have a follow up every 6 months but I moved to another state and forgot to tell my GP about it. I've had 4 strokes so forgetting is normal for me. I just took the pain for granted until it moved to my right pelvis; only worse. My GP sent me for ex-rays and I will get the results tomorrow via televisit. Surely I won't be told not to worry about it again. What, if anything, can be done about it? I would appreciate any feedback as I am really nervous right now.
