Colonoscopy results

[Dixie29]

Hi, I'm not sure if anyone will be able to help, just hoping there may be someone in the know!

My mum had a colonoscopy and a large polyp was found which they could not remove and now she has to have an urgent MRI I think to determine the extent/location of it. They took biopsies as I know is routine.

She is very worried as she has been reading her colonoscopy report and thinks it looks likely she has cancer although the consultant said he thought it looked benign.

It says the lesion was classified as "jnet type 2b". I have tried to Google it but it keeps mentioning cancer and I'm wondering if it's also a way of describing a harmless polyp or if this means it is likely to be a cancerous tumour.

I keep reassuring my mum however I'm not sure why it's been reported in this way.
Anyone know what it means?

Thanks!

They assign a subtype based on how the polyp/lesion appears to the physician performing the endoscopy. Could mean anything from benign to precancerous to having cancerous cells. It's just a classification.

It is not diagnostic though; the biopsy will yield that information. If the consultant thought it looked benign I'd be encouraged by that!

FWIW, my mother had to have a very large bowel polyp removed surgically when she was 80 years old. It ended up being completely benign and she had an uncomplicated recovery. I hope your mother fares just as well as mine did!

AFAIK a Jnet2B polyp is a type that has a low probability of being cancerous. Obviously biopsy will confirm, but try to help your mum not to worry excessively if at all possible. (I’m not a doc.). Sending good wishes.
