rectal drainage

7 years ago I had a total colostomy, but anus was not removed.

Then 3 years ago, anus was also removed.

have been experiencing a yellowish mucus draining from rectum for about 3 days - 

need to know why and where it's coming from?

was this due to cancer?

Oh wow ! I'm so sorry to hear about your condition . But how exactly does that work , if there's nothing anymore per your description on your health issue ? Where's the mucus coming out exactly from?

not sure - that's why I'm going to the doctor.

I had a pre-cancerous polyp 7 years ago

Ok , I wish you the best . I hope it won't be a serious thing .

Hello

​Did the surgeon remove your entire colon from a pre-cancerous polyp?  If you don't mind me asking why did they remove your anus too?
