Question 1

can a colonoscopy detect anal cancer?

Accepted Answer

Yes: If you are concerned or have symptoms such as blood in your bowl movements of rectal pain consult your doctor

Question 2

would a colonoscopy detect anal cancer? also could anal cancer develop within 8 months after a perfectly clean colonoscopy?

Accepted Answer

Cancer worry: Your concern about anal cancer indicates the need for you to see your doctor.  If and when you have been cleared of that consider seeing a clinical psychologist to be evaluated for health anxiety.  You certainly may not have this but the history is limited here.  Peace and good health.

Question 3

will a colonoscopy detect anal cancer/mass as well colon cancer? is the digital exam done before the colonoscopy is performed?

Accepted Answer

Yes and Yes: A colonoscopy would detect anal, rectal, colon cancer. Typically a rectal/digital exam is done first.

Question 4

can a dr. detect anal cancer through a colonoscopy?

Accepted Answer

Likely yes: As before the colonoscopy is done, a digital rectal examination is performed to visualize & palpate the area. Sometimes a biopsy of a concerning area is also needed though. See & ask your own gastroenterologist to get a better answer to this question as to what they saw during the exam.

Question 5

does a colonoscopy detect the presence of anal cancer? or does it just look at the rectum and colon?

Accepted Answer

: Yes, a colonoscopy along with visual inspection and a digital rectal exam suffice in diagnosing the presence of an anal tumor. A biopsy is needed to seal the diagnosis.

Question 6

i've had a negative colonoscopy and prostate/rectal sonogram, do they both detect anal cancer? is anal cancer common?

Accepted Answer

Anal cancer: can be detected by direct rectal exam or anoscopy, without colonoscopy.  Trananal prostate ultrasound does not detect  anal cancer.  Anal cancer is less common than colorectal cancer.  If digital exam and colonoscopy are both negative, it is unlikely that you have anal cancer.

Question 7

likelyhood anal cancer would be missed in 34yr male after normal colonoscopy 1yr ago? (not even hemorrhoids seen at time of test) have them now tho.

Accepted Answer

Unlikely: It is unlikely that you have anal cancer, but to be safe you should inform your primary care physician about your symptoms and undergo a physical examination.

Question 8

im 27 yrs old, last year i had bleeding when i pop, i went to colonoscopy and its ok, year after blood and itchy comes back.anal cancer or hemrroids?

Accepted Answer

Hemorrhoids more: likely.  Anal cancer is uncommon unless one has been engaging in receptive anal intercourse and got infected with HPV. Even hemorrhoids can lead to sufficient blood loss to cause anemia and you should consult a doctor for treatment.

Question 9

pain between tailbone/anus when sitting + constipation months. colonoscopy reg w/internal hemroids. scared results wrong.my dad passed of anal cancer.

Sounds like you have: Coccydynia,although this needs to be confirmed by a physical exam.You should seek the help of a Spine Surgeon.The condition can be helped by decreasing any pressure to the tender area,physical therapy,steroid injections,and it still may take months to resolve.
