A 41-year-old member asked:

Can an ultrasound really find cancer? Can today's ultrasound tests really locate tumors?

2 doctor answers3 doctors weighed in

That : That depends where the tumor is located. Ultrasound is excellent for evaluation of tumors in the thyroid, gallbladder, testicles, ovaries, and uterus; in fact, ultrasound is usually the preferred method to evaluate these organs. Ultrasound is also used to image the liver, kidneys, and spleen; however, tumors can be overlooked using ultrasound when imaging these organs. Oftentimes, ultrasound is used in conjunction with other modalities including ct and MRI in order to detect and evaluate masses in these and other organs. Ultrasound is not generally used to evaluate tumors in the lungs, stomach, bowel, and colon. Endorectal ultrasound can be used to evaluate the prostate, but the prostate is often evaluated using mri.

Why would my doc order an ab ultrasound when i just found out it wouldn't find colo cancer which is what he ordered it for?

Good question: Perhaps you should discuss this with the doctor who ordered the test. You are correct to wonder why an abdominal ultrasound would be ordered to specifically evaluate for colon cancer. Ultrasound is not a good test for colon cancer or other bowel pathologies. Perhaps the doctor is looking for something else?

A 38-year-old member asked:

Would gynaecologic ultrasound be able to detect everything? Would it detect cancer?

Dr. Wendy Askew

Definitely NOT.: A sonogram is more of a 'screening' tool, it will show changes that may be suggestive of a cancer, but in order to detect cancer some form of tissue sampling is required, (endometrial biopsy, or surgical removal of an organ for the pathologists to evaluate- before a cancer can be definitely diagnosed).
