Stage 1colorectal cancer
after removal is unlikely to cause the recurrence after its removal unless the tomor was very close to the resection line. This could be established by endoscopy
only whether it was recurrence. The other cause of per rectal bleeding
might be development of pile. If the blood is mixed with the stools it may be a pile only and if the bleeding is after defecation it might be recurrence. Your endoscopist will definitely establish it.
Regarding blood in urine there are many other causes but if it is established that it ia superficial bladder tomor it might be a new tumor
and has no relation with the colonic tumor.
