Question 1

can ultrasound detect colon cancer?

Accepted Answer

Rarely: Sometimes ultrasound will see a colon mass but this is uncommon. Spread of colon cancer to the lymph nodes or liver would be more common to see than the tumor itself.

Question 2

ct scan showed  spot on liver, have colon cancer but ultrasound came back negative does it mean it was wrong?

Accepted Answer

Spots: There are a variety of things that can be seen in the liver.  Not all of them are metastatic tumors. You can have benign nodules.  However, ct is a better way of viewing the liver.  It is difficult to know what the spot is without reading your radiology reports.  I would clarify with your doctor.

Question 3

sigmoid colon cancer removed surgically. after 10 days ultrasound impression is ' subacute small bowel intestinal obstruction and mild intraperitoneal free fluid collection. is this common?

Accepted Answer

No, not common: Bowel obstruction can occur due to post op adhesions(uncommon) or tumor left behind(this will happen if the cancer was advanced/late stage. Your doctor will have to sort out which of these two possibilities apply to your case.

Question 4

i'm a 28 year old female that has had right sided pelvic pain for a few months. i have had two clear ultrasounds and a clear ct scan with contrast. can right sided pelvic pain be a symptom of colon cancer? or any idea on what may be causing the pain?

Accepted Answer

Right pelvic pain: Have  other GI signs ?, nausea /vomiting? diarrhea? blood in stool? Able to eat? May be GI - gallbladder,   diverticulum ( meckels- but that is  associated with bleeding) ,  CT would note appendicitis and  i assume  kidney stones were considered .  But   I have seen women w/pelvic pain w/vaginal culture  of  ureoplasma/ mycoplasma  and responded to docycycline / or azithromycin f/u /MD

Question 5

would abd ultrasound and full blood count show something is wrong possibly colon cancer? no blood visible only loose stool. diagnosed with ibs.

Accepted Answer

Loose stool: At your age colon cancer would be very rare.  Abd US and full blood count are not the best tests to screen for colon cancer.  A colonoscopy would be the better test.  If your tests thus far are normal but still have symptoms, I would see your doctor for further testing.  Colonoscopy would be the best test as I stated before if all other tests were normal.

Question 6

i am a 47 year old woman 4 years colon cancer in remission. i still get my periods. it has been increasing heavy. my transvaginal ultrasound indicated complex cystic mass. smaller solid cystic mass on left adnexal 3.9cm. any info??

Accepted Answer

: Please see your Gyn for evaluation and treatment. Good luck

Question 7

can an ultra sound or a cat scan detect colon cancer?

Accepted Answer

Other good tests: Early colon cancer is not easily visible on Ultrasound. CT scan is under trials to find out its utility. Right now the best test is Colonoscopy where it is easy to visuallise early colon cancer and precursor lesions. Ask your doctor in case you may need one done. it is recommended for all adults aged 50 years or earlier if there is a family history of colon cancer. Ask your doctor's advice.

Question 8

hi can an abdominal ultrasound check for colon cancer spread? and if its normal dies that mean ca is confined to colon?

Accepted Answer

No: Cancer surveillance is usually done with a CT scan. Ultrasound is unable visualize most of the abdomen effectively. A normal ultrasound would not exclude spread of the cancer.

Question 9

would colon cancer show up on a pelvic or abdominal ultrasound test?

Accepted Answer

May, not reliable: A mass may be detectable, especially if there is large late stage cancer.  Ultrasound is not the prefered way to diagnose colon cancer; colonoscopy is.

Question 10

i had post menopause bleeding. not endometril cancer as biopsy clear. pap smear ok. ultrasound shows slight hyperplasia. but could it be colon cancer?

Accepted Answer

Please clarify...: Are you asking about a source of vaginal bleeding, bleeding per rectum, or are you not sure of the site of bleeding?  At age 51, you certainly qualify for and should undergo a screening colon exam (if you have not already accomplished same within the intervals established by medical convention).
