Entirely different: You have to wait for final report , don't worry for a pathologist it is as easy as distinguishing an apple from orange. Lymphoid follicles are normal lymph tissue common at that site.

Is carcinoid syndrome hereditary? My died at age 42 & i've already got bad stomach problems & colon polyps.

Is carcinoid syndrome hereditary? My died at age 42 & i've already got bad stomach problems & colon polyps.

Other neuroendocrine tumors are usually present in this syndrome, though. Familial carcinoids are more erratic in heritability. There is no formal test for suspected familial carcinoid. Symptoms of carcinoid syndrome include chronic flushing and diarrhea. ...Read more

Had a tubulovillous adenoma w/hgd removed via right-hemicoloectomy. Why does a repeat colonoscopy have to be done in a year if polyps grow slow?

Had a tubulovillous adenoma w/hgd removed via right-hemicoloectomy.  Why does a repeat colonoscopy have to be done  in a year if polyps grow slow?

A history of dysplastic polyps puts you at high risk of forming new polyps and the pace of growth is uncertain, especially in a young age group. There are clear guidelines put out by the american cancer society on the suggested followup for colon polyps. If your next colonscopy shows no polyps, they will extend the time interval. ...Read more

Colonoscopy 1 yr ago found 5 polyps; two Tubular adenoma under 2cm, two 2-5cm, one Tubulovillous 10-20CM. successfully removed. When should I go back?

Five years: Recommendations are that if you have adenomas five to ten years. Normal ten years. two small adenomas should not change this UNLESS you have risk factors such as a positive family history. In your case I think it reasonable and consistent with the guideliines to repeat in five years. ...Read more
