I have 3 first degree family members who died from pancreatic cancer. PC is often devastating and fast moving. So I am regularly screened by a gastroenterologist using endoscopic ultrasound to hopefully spot indications early. Recent results showed tiny white specks at the head of the pancreas. Just last year I was diagnosed with DCIS breast cancer using digital mammography which showed tiny white microcalcifications. What followup is recommended? A tisue biopsy? Needle aspiration or other procedure? Please advise.
