Pancreatic cancer cannot be seen on a negative ultrasound A vaginal ultrasound is a transvaginal ultrasound that is part of a gynecologic ultrasound that examines the uterus, both fallopian tubes, both ovaries, and the pelvic cavity by placing an ultrasound probe into the vagina. A vaginal ultrasound does not require holding urine and is mainly used for women who have had sexual intercourse. The pancreas is located in the supra-abdominal area and left quarter rib area. Abdominal ultrasound testing can examine the pancreas, and in pancreatic cancer, it can show an enlarged pancreas with an irregular shape or a mass in the pancreas, but it is not ideal for diagnosis of tumors less than 2 cm in size. Pancreatic cancer also needs to be diagnosed further based on blood biochemical tests, tumor marker tests such as CA199, CT, transendoscopic retrograde cholangiography, ultrasonic endoscopy, cytology or tissue biopsy. If you need to check your pancreas, it is recommended to go to the hospital for a reasonable examination under the guidance of a physician.
